+
+UHD software comes with several self-calibration utilities for
+minimizing IQ imbalance and DC offset. These utilities perform
+calibration sweeps using transmit leakage into the receive path (special
+equipment is not required). The results from a calibration are written

+the API allows the RX and TX LOs to be individually set, a change of one
+LO setting will be reflected in the other LO setting.
+
+The XCVR2450 does not support full-duplex mode, attempting to operate in
+full-duplex will result in transmit-only operation.

+
+\subsection dboards_dbsrxmod DBSRX - Modifying for other boards that USRP1
+
+Due to different clocking capabilities, the DBSRX will require
+modifications to operate on a non-USRP1 motherboard. On a USRP1
+motherboard, a divided clock is provided from an FPGA pin because the
+standard daughterboard clock lines cannot provided a divided clock.
+However, on other USRP motherboards, the divided clock is provided over
+the standard daughterboard clock lines.
+
+\subsubsection dboards_dbsrxmod_1 Step 1: Move the clock configuration resistor
+
+Remove **R193** (which is 10 Ohms, 0603 size), and put it on **R194**,
+which is empty. This is made somewhat more complicated by the fact that
+the silkscreen is not clear in that area. **R193** is on the back,
+immediately below the large beige connector, **J2**. **R194** is just
+below, and to the left of **R193**. The silkscreen for **R193** is ok,
+but for **R194**, it is upside down, and partially cut off. If you lose
+**R193**, you can use anything from 0 to 10 Ohms there.
+
+\subsubsection dboards_dbsrxmod_1 Step 2: Burn a new daughterboard id into the EEPROM
+
+With the daughterboard plugged-in, run the following commands:
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_db_eeprom --id=0x000d --unit=RX --args=<args> --slot=<slot>
+
+- **\<args\>** are device address arguments (optional if only one USRP
+ device is on your machine)
+- **\<slot\>** is the name of the daughterboard slot (optional if the
+ USRP device has only one slot)
+
+\subsection dboards_rfxmod RFX - Modify to use motherboard oscillator
+
+Older RFX boards require modifications to use the motherboard
+oscillator. If this is the case, UHD software will print a warning about
+the modification. Please follow the modification procedures below:
+
+- Step 1: Disable the daughterboard clocks**
+
+Move **R64** to **R84**. Move **R142** to **R153**.
+
+- Step 2: Connect the motherboard blocks
+
+Move **R35** to **R36**. Move **R117** to **R115**. These are all 0-Ohm,
+so if you lose one, just short across the appropriate pads.
+
+- Step 3: Burn the appropriate daughterboard ID into the EEPROM
+
+With the daughterboard plugged in, run the following commands: :
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_db_eeprom --id=<rx_id> --unit=RX --args=<args> --slot=<slot>
+ ./usrp_burn_db_eeprom --id=<tx_id> --unit=TX --args=<args> --slot=<slot>
+
+- `<rx_id>` choose the appropriate RX ID for your daughterboard
+ - **RFX400:** 0x0024
+ - **RFX900:** 0x0025
+ - **RFX1800:** 0x0034
+ - **RFX1200:** 0x0026
+ - **RFX2400:** 0x0027
+- `<tx_id>` choose the appropriate TX ID for your daughterboard
+ - **RFX400:** 0x0028
+ - **RFX900:** 0x0029
+ - **RFX1800:** 0x0035
+ - **RFX1200:** 0x002a
+ - **RFX2400:** 0x002b
+- `<args>` are device address arguments (optional if only one USRP device is on your machine)
+- `<slot>` is the name of the daughterboard slot (optional if the USRP device has only one slot)

-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-DBSRX - Mod
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Due to different clocking capabilities,
-the DBSRX will require modifications to operate on a non-USRP1 motherboard.
-On a USRP1 motherboard, a divided clock is provided from an FPGA pin
-because the standard daughterboard clock lines cannot provided a divided clock.
-However, on other USRP motherboards, the divided clock is provided
-over the standard daughterboard clock lines.
-
-**Step 1: Move the clock configuration resistor**
-
-Remove **R193** (which is 10 Ohms, 0603 size), and put it on **R194**, which is empty.
-This is made somewhat more complicated by the fact that the silkscreen is not clear in that area.
-**R193** is on the back, immediately below the large beige connector, **J2**.
-**R194** is just below, and to the left of **R193**.
-The silkscreen for **R193** is ok, but for **R194**,
-it is upside down, and partially cut off.
-If you lose **R193**, you can use anything from 0 to 10 Ohms there.
-
-**Step 2: Burn a new daughterboard id into the EEPROM**
-
-With the daughterboard plugged-in, run the following commands:
-::
-
- cd <install-path>/lib/uhd/utils
- ./usrp_burn_db_eeprom --id=0x000d --unit=RX --args=<args> --slot=<slot>
-
-* **<args>** are device address arguments (optional if only one USRP device is on your machine)
-* **<slot>** is the name of the daughterboard slot (optional if the USRP device has only one slot)
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-RFX - Mod
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Older RFX boards require modifications to use the motherboard oscillator.
-If this is the case, UHD software will print a warning about the modification.
-Please follow the modification procedures below:
-
-**Step 1: Disable the daughterboard clocks**
-
-Move **R64** to **R84**. Move **R142** to **R153**.
-
-**Step 2: Connect the motherboard blocks**
-
-Move **R35** to **R36**. Move **R117** to **R115**.
-These are all 0-Ohm, so if you lose one, just short across the appropriate pads.
-
-**Step 3: Burn the appropriate daughterboard ID into the EEPROM**
-
-With the daughterboard plugged-in, run the following commands:
-::
-
- cd <install-path>/lib/uhd/utils
- ./usrp_burn_db_eeprom --id=<rx_id> --unit=RX --args=<args> --slot=<slot>
- ./usrp_burn_db_eeprom --id=<tx_id> --unit=TX --args=<args> --slot=<slot>
-
-* **<rx_id>** choose the appropriate RX ID for your daughterboard

+\section general_tuning Tuning Notes
+
+\subsection general_tuning_process Two-stage tuning process
+
+A USRP device has two stages of tuning:
+
+- RF front-end: translates bewteen RF and IF
+- DSP: translates between IF and baseband
+
+In a typical use-case, the user specifies an overall center frequency
+for the signal chain. The RF front-end will be tuned as close as
+possible to the center frequency, and the DSP will account for the error
+in tuning between target frequency and actual frequency. The user may
+also explicitly control both stages of tuning through through the **tune_request_t** object, which allows for more advanced tuning.
+
+In general, Using UHD software's advanced tuning is highly recommended
+as it makes it easy to move the DC component out of your
+band-of-interest. This can be done by passing your desired LO offset to
+the **tune_request_t** object, and letting the UHD software handle the
+rest.
+
+The **tune_request_t** object can also be used with certain
+daughterboards to use Integer-N tuning instead of the default fractional
+tuning, allowing for better spur performance. The daughterboards that
+support this functionality are:
+
+- WBX (all revisions)
+- WBX-120
+- SBX (all revisions)
+- SBX-120
+- CBX
+- CBX-120
+
+\subsubsection general_tuning_rxchain Tuning the receive chain:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+//tuning to a desired center frequency
+usrp->set_rx_freq(target_frequency_in_hz);
+
+--OR--
+
+//advanced tuning with tune_request_t uhd::tune_request_t
+tune_req(target_frequency_in_hz, desired_lo_offset);
+tune_req.args = uhd::device_addr_t("mode_n=integer"); //to use Int-N tuning
+//fill in any additional/optional tune request fields...
+usrp->set_rx_freq(tune_req);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+More information can be found in uhd::tune_request_t.
+
+\subsection general_tuning_rfsettling RF front-end settling time
+
+After tuning, the RF front-end will need time to settle into a usable
+state. Typically, this means that the local oscillators must be given
+time to lock before streaming begins. Lock time is not consistent; it
+varies depending upon the device and requested settings. After tuning
+and before streaming, the user should wait for the **lo_locked** sensor
+to become true or sleep for a conservative amount of time (perhaps a
+second).
+
+\subsubsection general_tuning_waitcode Pseudo-code for dealing with settling time after tuning on receive:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->set_rx_freq(...);
+ sleep(1);
+ usrp->issue_stream_command(...);
+
+ --OR--
+
+ usrp->set_rx_freq(...);
+ while (not usrp->get_rx_sensor("lo_locked").to_bool()){
+ //sleep for a short time in milliseconds
+ }
+ usrp->issue_stream_command(...);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\section general_subdev Specifying the Subdevice to Use
+
+A subdevice specification string for USRP family devices is composed of:
+
+ <motherboard slot name>:<daughterboard frontend name>
+
+Ex: The subdev spec markup string to select a WBX on slot B.
+
+ B:0
+
+Ex: The subdev spec markup string to select a BasicRX on slot B.
+
+ B:AB
+
+ -- OR --
+
+ B:A
+
+ -- OR --
+
+ B:B
+
+\subsection general_subdev_slotnames USRP Family Motherboard Slot Names
+
+All USRP family motherboards have a first slot named **A:**. The USRP1 and the X3x0
+have two daughterboard subdevice slots, known as **A:** and **B:**.
+
+\subsection general_subdev_dbnames Daughterboard Frontend Names
+
+Daughterboard frontend names can be used to specify which signal path is
+used from a daughterboard. Most daughterboards have only one frontend **:0**.
+A few daughterboards (Basic, LF and TVRX2) have multiple
+frontend names available. The frontend names are documented in \ref page_dboards.
+
+\section general_ounotes Overflow/Underflow Notes
+
+<b>Note:</b> The following overflow/underflow notes do not apply to USRP1,
+which does not support the advanced features available in newer
+products.
+
+\subsection general_ounotes_overflow Overflow notes
+
+When receiving, the device produces samples at a constant rate.
+Overflows occurs when the host does not consume data fast enough. When
+UHD software detects the overflow, it prints an "O" or "D" to stdout,
+and pushes an inline message packet into the receive stream.
+
+<b>Network-based devices</b>: The host does not back-pressure the receive
+stream. When the kernel's socket buffer becomes full, it will drop
+subsequent packets. UHD software detects the overflow as a discontinuity
+in the packet's sequence numbers, and pushes an inline message packet
+into the receive stream. In this case the character "D" is printed to
+stdout as an indication.
+
+<b>Other devices</b>: The host back-pressures the receive stream.
+Therefore, overflows always occur in the device itself. When the
+device's internal buffers become full, streaming is shut off, and an
+inline message packet is sent to the host. In this case the character
+"O" is printed to stdout as an indication. If the device was in
+continuous streaming mode, the UHD software will automatically restart
+streaming when the buffer has space again.
+
+\subsection general_ounotes_underrun Underrun notes
+
+When transmitting, the device consumes samples at a constant rate.
+Underflow occurs when the host does not produce data fast enough. When
+UHD software detects the underflow, it prints a "U" to stdout, and
+pushes a message packet into the async message stream.
+
+<b>Note:</b> "O" and "U" message are generally harmless, and just mean the host machine can't keep up with the requested rates.
+
+\section general_threading Threading Notes
+
+\subsection general_threading_safety Thread safety notes
+
+For the most part, UHD software is thread-safe. Please observe the
+following limitations:
+
+<b>Fast-path thread requirements:</b> There are three fast-path methods for
+a device: `send()`, `recv()`, and `recv_async_msg()`. All three
+methods are thread-safe and can be called from different thread
+contexts. For performance, the user should call each method from a
+separate thread context. These methods can also be used in a
+non-blocking fashion by using a timeout of zero.
+
+<b>Slow-path thread requirements:</b> It is safe to change multiple
+settings simultaneously. However, this could leave the settings for a
+device in an uncertain state. This is because changing one setting could
+have an impact on how a call affects other settings. Example: setting
+the channel mapping affects how the antennas are set. It is recommended
+to use at most one thread context for manipulating device settings.
+
+\subsection general_threading_prio Thread priority scheduling
+
+When UHD software spawns a new thread, it may try to boost the thread's
+scheduling priority. If setting the new priority fails, the UHD software
+prints a warning to the console, as shown below. This warning is harmless;
+it simply means that the thread will retain a normal or default scheduling priority.
+
+ UHD Warning:
+ Unable to set the thread priority. Performance may be negatively affected.
+ Please see the general application notes in the manual for instructions.
+ EnvironmentError: OSError: error in pthread_setschedparam
+
+<b>Linux Notes:</b>
+
+Non-privileged users need special permission to change the scheduling
+priority. Add the following line to the file `/etc/security/limits.conf`:
+
+ @GROUP - rtprio 99
+
+Replace `GROUP` with a group in which your user is a member. You may need
+to log out and log back into the account for the settings to take effect.
+In most Linux distributions, a list of groups and group members can be found in the file `/etc/group`.
+
+\section general_misc Miscellaneous Notes
+
+\subsection general_misc_dynamic Support for dynamically loadable modules
+
+For a module to be loaded at runtime, it must be:
+
+- found in the `UHD_MODULE_PATH` environment variable,
+- installed into the `\<install-path\>/share/uhd/modules` directory,
+- or installed into `/usr/share/uhd/modules` directory (UNIX only).
+
+\subsection general_misc_prints Disabling or redirecting prints to stdout
+
+The user can disable the UHD library from printing directly to stdout by
+registering a custom message handler. The handler will intercept all
+messages, which can be dropped or redirected. Only one handler can be
+registered at a time. Make **register_handler** your first call into
+the UHD library:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+#include <uhd/utils/msg.hpp>
+
+void my_handler(uhd::msg::type_t type, const std::string &msg){
+//handle the message...
+}
+
+uhd::msg::register_handler(&my_handler);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-**Fast-path thread requirements:**
-There are three fast-path methods for a device: **send()**, **recv()**, and **recv_async_msg()**.
-All three methods are thread-safe and can be called from different thread contexts.
-For performance, the user should call each method from a separate thread context.
-These methods can also be used in a non-blocking fashion by using a timeout of zero.
-
-**Slow-path thread requirements:**
-It is safe to change multiple settings simultaneously. However,
-this could leave the settings for a device in an uncertain state.
-This is because changing one setting could have an impact on how a call affects other settings.
-Example: setting the channel mapping affects how the antennas are set.
-It is recommended to use at most one thread context for manipulating device settings.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-Thread priority scheduling
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-When UHD software spawns a new thread it may try to boost the thread's scheduling priority.
-When setting the priority fails, the UHD software prints out an error.
-This error is harmless; it simply means that the thread will have a normal scheduling priority.
-
-**Linux Notes:**
-
-Non-privileged users need special permission to change the scheduling priority.
-Add the following line to **/etc/security/limits.conf**:
-::::::::::::::::::::::::::::::::::::::::::::::::::::::::
-
- @<my_group> - rtprio 99
-
-Replace **<my_group>** with a group to which your user belongs.
-Settings will not take effect until the user is in a different login session.
-
--------------------
-Miscellaneous Notes
--------------------
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Support for dynamically loadable modules
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-For a module to be loaded at runtime, it must be:
-
-* found in the **UHD_MODULE_PATH** environment variable,
-* installed into the **<install-path>/share/uhd/modules** directory,
-* or installed into **/usr/share/uhd/modules** directory (UNIX only).
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Disabling or redirecting prints to stdout
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-The user can disable the UHD library from printing directly to stdout by registering a custom message handler.
-The handler will intercept all messages, which can be dropped or redirected.
-Only one handler can be registered at a time.
-Make **register_handler** your first call into the UHD library:
-
-::
-
- #include <uhd/utils/msg.hpp>
-
- void my_handler(uhd::msg::type_t type, const std::string &msg){
- //handle the message...
- }
-
- uhd::msg::register_handler(&my_handler);

+\section xgpio_fpanel The X3x0 Front Panel GPIO
+
+The X3x0 is the first USRP device to offer an auxiliary GPIO connection
+on the motherboard itself (independent of the daughterboards). These
+GPIO pins are controlled directly by the FPGA, where they are controlled
+by an ATR (Automatic Transmit / Receive). This allows them to be toggled
+simultaneously with other radio-level changes (e.g., enabling or
+disabling a TX or RX mixer).

+\subsection xgpio_fpanel_atr Explaining ATR
+
+ATR works by defining the value of the GPIO pins for certain states of
+the radio. This is the "automatic" part of it. For example, you can tell
+UHD that when the radio is transmitting and receiving (full duplex),
+GPIO6 should be high, but when it is only transmitting, GPI06 should be
+low. This state machine is set up using a series of GPIO attributes,
+with paired values and a mask, which you will want to define for the
+GPIO pins you intend to use. To set up the ATR, you use uhd::usrp::multi_usrp::set_gpio_attr().
+
+- **CTRL**: Is this pin controlled by ATR (automatic), or by manual
+ control only?
+- **DDR**: "Data Direction Register" - defines whether or not a GPIO
+ is an output or an input.
+- **OUT**: Manually set the value of a pin (only to be used in non-ATR
+ mode).
+- **ATR_0X**: The status of the pins when the radio is **idle**.
+- **ATR_RX**: The status of the pins when the radio is only
+ **receiving**.
+- **ATR_TX**: The status of the pins when the radio is only
+ **transmitting**.
+- **ATR_XX**: The status of the pins when the radio is in
+ **full-duplex** mode.
+
+The counterpart to setting the ATR (the "getter"), is called
+uhd::usrp::multi_usrp::get_gpio_attr().
+t has the exact same attributes as above, and has
+one more:
+
+- **READBACK**: Readback the GPIOs marked as inputs.
+
+\subsection xgpio_fpanel_xample An Example
+
+The front panel X3x0 GPIO bank is enumerated in the motherboard property
+tree (`*<mb_path>/gpio/FP0/*`), and so is easily accessible through
+the standard uhd::usrp::multi_usrp UHD interface.
+
+You can discover this using the uhd::usrp::multi_usrp::get_gpio_banks() function.
+This will tell you that there is a GPIO bank on your
+X3x0 called "FP0". This is the bank we want to set-up.
+
+Let's say we want to use GPIO6 for an external amp. We want it to be
+automatically controlled by ATR as an output, and we want it to be high
+when we are transmitting, and low in all other cases. We are also using
+GPIO4, which we want to control manually, as an output. We can set this
+up with the following code:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ // set up our masks, defining the pin numbers
+ #define AMP_GPIO_MASK (1 << 6)
+ #define MAN_GPIO_MASK (1 << 4)
+
+ #define ATR_MASKS (AMP_GPIO_MASK | MAN_GPIO_MASK)
+
+ // set up our values for ATR control: 1 for ATR, 0 for manual
+ #define ATR_CONTROL (AMP_GPIO_MASK & ~MAN_GPIO_MASK)
+
+ // set up the GPIO directions: 1 for output, 0 for input
+ #define GPIO_DDR (AMP_GPIO_MASK & ~MAN_GPIO_MASK)
+
+ // assume an existing USRP device handle, called "usrp_x300"
+
+ // now, let's do the basic ATR setup
+ usrp_x300->set_gpio_attr("FP0", "CTRL", ATR_CONTROL, ATR_MASKS);
+ usrp_x300->set_gpio_attr("FP0", "DDR", GPIO_DDR, ATR_MASKS);
+
+ // let's manually set GPIO4 high
+ usrp_x300->set_gpio_attr("FP0", "OUT", 1, MAN_GPIO_MASK);
+
+ // finally, let's set up GPIO6 as we described above
+ usrp_x300->set_gpio_attr("FP0", "ATR_0X", 0, AMP_GPIO_MASK);
+ usrp_x300->set_gpio_attr("FP0", "ATR_RX", 0, AMP_GPIO_MASK);
+ usrp_x300->set_gpio_attr("FP0", "ATR_TX", 0, AMP_GPIO_MASK);
+ usrp_x300->set_gpio_attr("FP0", "ATR_XX", 0, AMP_GPIO_MASK);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After the above code is run, the ATR in the FPGA will automatically
+control GPIO6, as we have described, based on the radio state, and we
+have direct manual control over GPIO4.

+
+The GPSDO is capable of supplying a 3V for active GPS antennas or

+
+\section gpsdo_install Installation Instructions
+
+Instructions for mounting the GPSDO kit onto your USRP device can be
+found here: http://www.ettus.com/content/files/gpsdo-kit_2.pdf
+
+\subsection gspdo_install_post Post-installation Task (N-Series only)
+
+<b>Note:</b> The following instructions are only necessary for UHD 3.4.\*
+and below.
+
+This is necessary if you require absolute GPS time in your application
+or need to communicate with the GPSDO to obtain location, satellite
+info, etc. If you only require 10 MHz and PPS signals for reference or
+MIMO use (see \ref page_sync), it is not necessary to perform this step.
+
+To configure the USRP to communicate with the GPSDO, use the
+`usrp_burn_mb_eeprom` utility:
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="gpsdo=internal"
+
+ -- restore original setting --
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="gpsdo=internal"
+
+\section gpsdo_use Using the GPSDO in Your Application
+
+By default, if a GPSDO is detected at startup, the USRP will be
+configured to use it as a frequency and time reference. The internal
+VITA timestamp will be initialized to the GPS time, and the internal
+oscillator will be phase-locked to the 10 MHz GPSDO reference. If the
+GPSDO is not locked to satellites, the VITA time will not be
+initialized.
+
+GPS data is obtained through the **mboard_sensors** interface. To
+retrieve the current GPS time, use the **gps_time** sensor:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->get_mboard_sensor("gps_time");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The returned value will be the current epoch time, in seconds since
+January 1, 1970. This value is readily converted into human-readable
+format using the **time.h** library in C, **boost::posix_time** in C++,
+etc.
+
+Other information can be fetched as well. You can query the lock status
+with the **gps_locked** sensor, as well as obtain raw NMEA sentences
+using the **gps_gprmc**, and **gps_gpgga** sensors. Location
+information can be parsed out of the **gps_gpgga** sensor by using **gpsd**
+or another NMEA parser.

+To install the GPSDO, you must insert it into the slot on the board near
+the 10 MHz Reference SMA. Keep in mind that the two sides of the GPSDO
+have a different number of pins. When inserting the GPSDO, make sure to
+press down firmly and evenly. When turning on the USRP X3x0 device, a
+green LED should illuminate on the GPSDO. This signifies that the unit
+has successfully been placed.
+
+<b>NOTE: The pins on the GPSDO are very fragile. Be sure to press down
+evenly, or the pins may bend or break. Once the GPSDO is in place, we
+very highly discourage further removal, as this also risks damaging the
+pins.</b>
+
+\section gpsdox_using Using the GPSDO in Your Application
+
+By default, if a GPSDO is detected at startup, the USRP will be
+configured to use it as a frequency and time reference. The internal
+VITA timestamp will be initialized to the GPS time, and the internal
+oscillator will be phase-locked to the 10MHz GPSDO reference. If the
+GPSDO is not locked to satellites, the VITA time will not be
+initialized.
+
+GPS data is obtained through the **mboard_sensors** interface. To
+retrieve the current GPS time, use the **gps_time** sensor:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->get_mboard_sensor("gps_time");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The returned value will be the current epoch time, in seconds since
+January 1, 1970. This value is readily converted into human-readable
+format using the **time.h** library in C, **boost::posix_time** in C++,
+etc.
+
+Other information can be fetched as well. You can query the lock status
+with the **gps_locked** sensor, as well as obtain raw NMEA sentences
+using the **gps_gprmc**, and **gps_gpgga** sensors. Location
+information can be parsed out of the **gps_gpgga** sensor by using **gpsd**
+or another NMEA parser.

+/*! \page page_identification Device Identification Notes
+
+\tableofcontents
+
+\section id_identifying Identifying USRP Devices
+
+Devices are addressed through key/value string pairs. These string pairs
+can be used to narrow down the search for a specific device or group of
+devices. Most UHD utility applications and examples have an `--args`
+parameter that takes a device address, which is expressed as a delimited
+string.
+
+See device_addr.hpp for reference.
+
+\subsection id_identifying_common Common device identifiers
+
+Every device has several ways of identifying it on the host system:
+
+Identifier | Key | Notes | Example
+-----------|----------|-----------------------------------------------------------|---------------------------------
+Serial | serial | globally unique identifier | 12345678
+Address | addr | unique identifier on a network | 192.168.10.2
+Resource | resource | unique identifier for USRP RIO devices (over PCI Express) | RIO0
+Name | name | optional user-set identifier | my_usrp1 (User-defined value)
+Type | type | hardware series identifier | usrp1, usrp2, b200, x300, ...
+
+\subsection id_identifying_cmdline Device discovery via command line
+
+Devices attached to your system can be discovered using the
+`uhd_find_devices` program. This program scans your system for
+supported devices and prints out an enumerated list of discovered
+devices and their addresses. The list of discovered devices can be
+narrowed down by specifying device address args.
+
+ uhd_find_devices
+
+Device address arguments can be supplied to narrow the scope of the
+search.
+
+ uhd_find_devices --args="type=usrp1"
+
+ -- OR --
+
+ uhd_find_devices --args="serial=12345678"
+
+\subsection id_identifying_api Device discovery through the API
+
+The device::find() API call searches for devices and returns a list
+of discovered devices.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ uhd::device_addr_t hint; //an empty hint discovers all devices
+ uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The `hint` argument can be populated to narrow the scope of the search.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ uhd::device_addr_t hint;
+ hint["type"] = "usrp1";
+ uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+
+ -- OR --
+
+ uhd::device_addr_t hint;
+ hint["serial"] = "12345678";
+ uhd::device_addrs_t dev_addrs = uhd::device::find(hint);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\subsection id_identifying_props Device properties
+
+Properties of devices attached to your system can be probed with the
+`uhd_usrp_probe` program. This program constructs an instance of the
+device and prints out its properties, such as detected daughterboards,
+frequency range, gain ranges, etc...
+
+<b>Usage:</b>
+
+ uhd_usrp_probe --args <device-specific-address-args>
+
+\section id_naming Naming a USRP Device
+
+For convenience purposes, users may assign a custom name to their USRP
+device. The USRP device can then be identified via name, rather than a
+difficult to remember serial or address.
+
+A name has the following properties:
+
+- is composed of ASCII characters
+- is 0-20 characters
+- is not required to be unique
+
+\subsection id_naming_set Set a custom name
+
+Run the following commands:
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="name=lab1_xcvr"
+
+\subsection id_naming_discovery Discovery via name
+
+The keyword `name` can be used to narrow the scope of the search.
+Example with the find devices utility:
+
+ uhd_find_devices --args="name=lab1_xcvr"
+
+ -- OR --
+
+ uhd_find_devices --args="type=usrp1, name=lab1_xcvr"

+\subsection bootloader OctoClock bootloader
+
+If you purchased your OctoClock device before Ethernet functionality was introduced, or if your unit's

+the primary firmware.
+
+To load the bootloader onto the OctoClock, two things are needed:
+
+- AVR programmer
+- AVRdude software
+
+Connect the AVR programmer to J108, as specified on the <a href="http://files.ettus.com/schematics/octoclock/octoclock.pdf">
+schematics</a>. Once you verify that the programmer is properly connected, run the following commands to burn the firmware:

+
+**Note:** On Linux, **sudo** must be used with the **avrdude** command.
+
+Once the bootloader has been burned, power-cycle your OctoClock device and refer to the below instructions on burning the OctoClock's
+primary firmware.
+
+\subsection application Primary Octoclock firmware
+
+To load firmware onto the OctoClock, you must use the *octoclock_firmware_burner* utility, specifying the IP
+address of the OctoClock device, as follows:
+
+ octoclock_firmware_burner --addr=192.168.10.3
+
+\section octoclock_network Setting Up Networking
+
+\subsection host_interface Setting up the host interface
+
+The OctoClock communicates with the host machine at the UDP layer over Gigabit Ethernet. The default device
+of the OctoClock is **192.168.10.3**. You will need to configure the host machine's Ethernet interface with
+a static IP address to enable communication. An address of **192.168.10.1** and a subnet mask of
+**255.255.255.0** is recommended.
+
+**Note:** When using UHD software, if an IP address for the OctoClock is not specified, the software will
+use UDP broadcast packets to locate the OctoClock. On some systems, the firewall will block UDP broadcast
+packets. It is recommended that you change your firewall settings.
+
+\subsection changing_ip Changing the OctoClock's IP address
+
+You may need to change the OctoClock's IP address for various reasons.
+
+- To satisfy your particular network configuration
+- To use multiple OctoClocks on the same host computer
+
+To change the OctoClock's IP address, run the following commands (using the default IP address as an example):
+
+ cd <install path>/lib/uhd/utils
+ ./octoclock_burn_eeprom --args="<optional device args>" --values="ip-addr=192.168.10.3"
+
+\section addressing Addressing the Device
+
+There are two ways to address the OctoClock from UHD software: the IP address, and the serial.
+
+To use the IP address, address it as follows:
+
+ "addr=<ip address>"
+
+If you want to use multiple OctoClock devices, address it as follows:
+
+ "addr0=<ip address 1>,addr1=<ip address 2>"
+
+To use the serial, address it as follows:
+
+ "serial=<serial>"
+
+\section hardware_setup Hardware Setup Notes
+
+\subsection front_panel_leds Front Panel LEDs
+
+The LEDs on the front panel show the current status of the device. Each LED is described below:
+
+- **Internal:** the device is using the internal GPSDO
+- **External:** the device is using an external reference
+- **Status:** the device is successfully distributing a 10 MHz and PPS signal
+- **PPS:** lights up when a PPS signal is detected
+- **GPS Lock:** the internal GPSDO has achieved a lock (not necessary to distribute the signals)
+- **Power:** the device is receiving power
+
+\subsection front_panel_switch Front Panel Switch
+
+The front panel switch, marked **Primary Ref** determines which reference the OctoClock will prefer to use. If it is receiving
+both an internal and external reference, the device will use whichever one the switch specifies.
+
+However, if it is only receiving an internal reference, it will use this reference no matter what position the switch is in.
+The same applies for an external signal.
+
+\section misc Miscellaneous
+
+\subsection available_sensors Available Sensors
+
+The following sensors are available on both the OctoClock and Octoclock-G; these can be queried through the
+<a href="classuhd_1_1octoclock.html">API</a>.
+
+- **ext_ref_detected:** whether or not the device detects an external reference
+- **gps_detected:** whether or not the device detects an internal GPSDO
+- **using_ref:** which reference the device is using (internal or external)
+- **switch_pos:** the position of the front switch (internal or external)
+
+On the OctoClock-G, the following sensors are added:
+
+- **gps_gpgga:** the latest GPGGA string sent by the GPSDO
+- **gps_gprmc:** the latest GPRMC string sent by the GPSDO
+- **gps_time:** the time reported by the GPSDO
+- **gps_locked:** whether or not the GPSDO is locked (true/false)
+- **gps_servo:** the latest debug trace information sent by the GPSDO

+\section stream_intro Introduction to Streaming
+
+The concept of streaming refers to the transportation of samples between
+host and device. A stream is an object that facilitates streaming
+between host application and device. An RX stream allows the user to
+receive samples from the device. A TX stream allows the user to transmit
+samples to the device.
+
+\section stream_lle Link Layer Encapsulation
+
+The VITA49 standard provides encapsulation for sample data across a link
+layer. On all second generation hardware (and later), samples are
+encapsulated into VRT IF data packets. These packets also provide sample
+decoration such as stream time and burst flags. Sample decoration is
+exposed to the user in the form of RX and TX metadata structs.
+
+The length of an IF data packet can be limited by several factors:
+
+- **MTU of the link layer:** network card, network switch
+- **Buffering on the host:** frame size in a ring buffer
+- **Buffering on the device:** size of BRAM FIFOs
+
+\section stream_datatypes Data Types
+
+There are two important data types to consider when streaming:
+
+- The data type of the samples used on the host for processing
+- The data type of the samples sent through the link-layer
+
+\subsection stream_datatypes_cpu The host/CPU data type
+
+The host data type refers to the format of samples used in the host for
+baseband processing. Typically, the data type is complex baseband such

+
+\subsection stream_datatypes_otw The link-layer data type
+
+The link-layer or "over-the-wire" data type refers to the format of the
+samples sent through the link. Typically, this data type is **complex-int16**.
+However, to increase throughput over the link-layer,
+at the expense of precision, **complex-int8** may be used.
+
+\subsection stream_datatypes_conv Conversion

+/*! \page page_sync Synchronization Application Notes
+
+\tableofcontents
+
+The following application notes explain how to synchronize multiple USRP
+devices with the goal of transmitting or receiving time-aligned samples
+for MIMO or other applications requiring multiple USRP devices operating
+synchronously.
+
+<b>Note:</b> The following synchronization notes do not apply to USRP1,
+which does not support the advanced features available in newer
+products.
+
+\section sync_commonref Common Reference Signals
+
+USRP devices take two reference signals in order to synchronize clocks
+and time:
+
+- A 10MHz reference to provide a single frequency reference for both
+ devices.
+- A pulse-per-second (PPS) to synchronize the sample time across
+ devices.
+- A MIMO cable transmits an encoded time message from one device to
+ another.
+
+\subsection sync_commonref_pps PPS and 10 MHz reference signals
+
+Connect the front panel SMA connectors to the reference sources.
+Typically, these signals are provided by an external GPSDO. However,
+some USRP models can provide these signals from an optional internal
+GPSDO.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+usrp->set_clock_source("external");
+usrp->set_time_source("external");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+<b>Note:</b> Sometimes the delay on the PPS signal will cause it to arrive
+inside the timing margin the FPGA sampling clock, causing PPS edges to
+be separated by less or more than 100 million cycles of the FPGA clock.
+If this is the case, you can change the edge reference of the PPS signal
+with this parameter:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+usrp->set_time_source("_external_");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+<b>Note2:</b> For users generating their own signals for the external SMA
+connectors, the PPS should be clocked from the 10MHz reference. See the
+application notes for your device for specific signal requirements.
+
+\subsection sync_commonref_mimo MIMO cable reference signals
+
+Use the MIMO expansion cable to share reference sources (USRP2 and
+N-Series). The MIMO cable can be used synchronize one device to another
+device. Users of the MIMO cable may use Method 1 (explained below) to
+synchronize multiple pairs of devices.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->set_clock_source("mimo");
+ usrp->set_time_source("mimo");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\section sync_time Synchronizing the Device Time
+
+The purpose of the PPS signal is to synchronously latch a time into the
+device. You can use the `set_time_next_pps(...)` function to either
+initialize the sample time to 0 or an absolute time, such as GPS time or
+UTC time. For the purposes of synchronizing devices, it doesn't matter
+what time you initialize to when using `set_time_next_pps(...)`.
+
+\subsection sync_time_reg Method 1 - poll the USRP time registers
+
+One way to initialize the PPS edge is to poll the "last PPS" time from
+the USRP device. When the last PPS time increments, the user can
+determine that a PPS has occurred:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ const uhd::time_spec_t last_pps_time = usrp->get_time_last_pps();
+ while (last_pps_time == usrp->get_time_last_pps()){
+ //sleep 100 milliseconds (give or take)
+ }
+ usrp->set_time_next_pps(uhd::time_spec_t(0.0));
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\subsection sync_time_gpsdo Method 2 - query the GPSDO for seconds
+
+Most GPSDOs can be configured to output a NMEA string over the serial
+port once every PPS. The user can wait for this string to determine the
+PPS edge, and the user can also parse this string to determine GPS time:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ //call user's function to wait for NMEA message...
+ usrp->set_time_next_pps(uhd::time_spec_t(0.0));
+
+ -- OR --
+
+ //call user's function to wait for NMEA message...
+ //call user's function to parse the NMEA message...
+ usrp->set_time_next_pps(uhd::time_spec_t(gps_time+1));
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\subsection sync_time_internalgps Method 3 - internal GPSDO
+
+USRP devices with internal GPSDOs properly configured will automatically
+configure themselves to set the VITA time to current UTC time. See \ref page_gpsdo
+for more details.
+
+\subsection sync_time_mimocable Method 4 - MIMO cable
+
+A USRP device can synchronize its time to another USRP device via the
+MIMO cable. Unlike the other methods, this does not use a real "pulse
+per second". Rather, the USRP device sends an encoded time message over
+the MIMO cable. The slave device will automatically synchronize to the
+time on the master device. See \ref usrp2_mimocable for more detail.
+
+\section sync_phase Synchronizing Channel Phase
+
+\subsection sync_phase_cordics Align CORDICs in the DSP
+
+In order to achieve phase alignment between USRP devices, the CORDICS in
+both devices must be aligned with respect to each other. This is easily
+achieved by issuing stream commands with a time spec property, which
+instructs the streaming to begin at a specified time. Since the devices
+are already synchronized via the 10 MHz and PPS inputs, the streaming
+will start at exactly the same time on both devices. The CORDICs are
+reset at each start-of-burst command, so users should ensure that every
+start-of-burst also has a time spec set.
+
+For receive, a burst is started when the user issues a stream command.
+This stream command should have a time spec set:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ uhd::stream_cmd_t stream_cmd(uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_DONE);
+ stream_cmd.num_samps = samps_to_recv;
+ stream_cmd.stream_now = false;
+ stream_cmd.time_spec = time_to_recv;
+ usrp->issue_stream_cmd(stream_cmd);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For transmit, a burst is started when the user calls send(). The
+metadata should have a time spec set: :
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ uhd::tx_metadata_t md;
+ md.start_of_burst = true;
+ md.end_of_burst = false;
+ md.has_time_spec = true;
+ md.time_spec = time_to_send;
+
+ //send a single packet
+ size_t num_tx_samps = tx_streamer->send(buffs, samps_to_send, md);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\subsection sync_phase_lo Align LOs in the front-end (SBX, WBX, CBX)
+
+Using timed commands, multiple frontends can be tuned at a specific
+time. This timed-tuning ensures that the phase offsets between VCO/PLL
+chains will remain constant after each re-tune. See notes below:
+
+- There is a random phase offset between any two frontends
+- This phase offset is different for different LO frequencies
+- This phase offset remains constant after retuning
+ - Due to a divider, WBX phase offset will be randomly +/- 180 deg after re-tune
+- This phase offset will drift over time due to thermal and other characteristics
+- Periodic calibration will be necessary for phase-coherent applications
+
+Code snippet example, tuning with timed commands: :
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ //we will tune the frontends in 100ms from now
+ uhd::time_spec_t cmd_time = usrp->get_time_now() + uhd::time_spec_t(0.1);
+
+ //sets command time on all devices
+ //the next commands are all timed
+ usrp->set_command_time(cmd_time);
+
+ //tune channel 0 and channel 1
+ usrp->set_rx_freq(1.03e9, 0); // Channel 0
+ usrp->set_rx_freq(1.03e9, 1); // Channel 1
+
+ //end timed commands
+ usrp->clear_command_time();
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\subsection sync_phase_lootherfe Align LOs in the front-end (others)
+
+After tuning the RF front-ends, each local oscillator may have a random
+phase offset due to the dividers in the VCO/PLL chains. This offset will
+remain constant after the device has been initialized, and will remain
+constant until the device is closed or re-tuned. This phase offset is
+typically removed by the user in MIMO applications, using a training
+sequence to estimate the offset. It will be necessary to re-align the
+LOs after each tune command.

+\section transport_intro Introduction
+
+A transport is the layer between the packet interface and a device IO
+interface. The advanced user can pass optional parameters into the
+underlying transport layer through the device address. These optional
+parameters control how the transport object allocates memory, resizes
+kernel buffers, spawns threads, etc. When not spcified, the transport
+layer will use values for these parameters that are known to perform
+well on a variety of systems. The transport parameters are defined below
+for the various transports in the UHD software:
+
+\section transport_udp UDP Transport (Sockets)
+
+The UDP transport is implemented with user-space sockets. This means
+standard Berkeley sockets API using send()/recv().
+
+\subsection transport_udp_params Transport parameters
+
+The following parameters can be used to alter the transport's default
+behavior:
+
+- `recv_frame_size:` The size of a single receive buffer in bytes
+- `num_recv_frames:` The number of receive buffers to allocate
+- `send_frame_size:` The size of a single send buffer in bytes
+- `num_send_frames:` The number of send buffers to allocate
+
+<b>Notes:</b>
+- `num_recv_frames` does not affect performance.
+- `num_send_frames` does not affect performance.
+- `recv_frame_size` and `send_frame_size` can be used
+ to increase or decrease the maximum number of samples per packet. The
+ frame sizes default to an MTU of 1472 bytes per IP/UDP packet and may be
+ increased if permitted by your network hardware.
+
+\subsection transport_udp_flow Flow control parameters
+
+The host-based flow control expects periodic update packets from the
+device. These update packets inform the host of the last packet consumed
+by the device, which allows the host to determine throttling conditions
+for the transmission of packets. The following mechanisms affect the
+transmission of periodic update packets:
+
+- `ups_per_fifo:` The number of update packets for each FIFO's
+ worth of bytes sent into the device
+- `ups_per_sec:` The number of update packets per second (defaults
+ to 20 updates per second)
+
+\subsection transport_udp_sockbufs Resize socket buffers
+
+It may be useful to increase the size of the socket buffers to move the
+burden of buffering samples into the kernel or to buffer incoming
+samples faster than they can be processed. However, if your application
+cannot process samples fast enough, no amount of buffering can save you.
+The following parameters can be used to alter socket's buffer sizes:
+
+- `recv_buff_size:` The desired size of the receive buffer in
+ bytes
+- `send_buff_size:` The desired size of the send buffer in bytes
+
+<b>Note:</b> Large send buffers tend to decrease transmit performance.
+
+\subsection transport_udp_latency Latency Optimization
+
+Latency is a measurement of the time it takes a sample to travel between
+the host and device. Most computer hardware and software is bandwidth
+optimized, which may negatively affect latency. If your application has
+strict latency requirements, please consider the following notes:
+
+<b>Note1:</b> The time taken by the device to populate a packet is
+proportional to the sample rate. Therefore, to improve receive latency,
+configure the transport for a smaller frame size.
+
+<b>Note2:</b> For overall latency improvements, look for "Interrupt
+Coalescing" settings for your OS and ethernet chipset. It seems the
+Intel ethernet chipsets offer fine-grained control in Linux. Also,
+consult:
+
+- <http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.prftungd/doc/prftungd/interrupt_coal.htm>
+
+\subsection transport_udp_linux Linux specific notes
+
+On Linux, the maximum buffer sizes are capped by the sysctl values
+`net.core.rmem_max` and `net.core.wmem_max`. To change the maximum
+values, run the following commands: :
+
+ sudo sysctl -w net.core.rmem_max=<new value>
+ sudo sysctl -w net.core.wmem_max=<new value>
+
+Set the values permanently by editing `/etc/sysctl.conf`.
+
+\subsection transport_udp_windows Windows specific notes
+
+**UDP send fast-path:** It is important to change the default UDP
+behavior such that 1500 byte packets still travel through the fast path
+of the sockets stack. This can be adjusted with the
+FastSendDatagramThreshold registry key:
+
+- FastSendDatagramThreshold registry key documented here:
+
+ - <http://www.microsoft.com/windows/windowsmedia/howto/articles/optimize_web.aspx#appendix_e>
+
+- Double click and run
+ `<install-path>/share/uhd/FastSendDatagramThreshold.reg`
+- A system reboot is recommended after the registry key change.
+
+<b>Power profile:</b> The Windows power profile can seriously impact
+instantaneous bandwidth. Application can take time to ramp-up to full
+performance capability. It is recommended that users set the power
+profile to "high performance".
+
+\section transport_usb USB Transport (LibUSB)
+
+The USB transport is implemented with LibUSB. LibUSB provides an
+asynchronous API for USB bulk transfers.
+
+\subsection transport_usb_params Transport parameters
+
+The following parameters can be used to alter the transport's default
+behavior:
+
+- `recv_frame_size:` The size of a single receive transfers in
+ bytes
+- `num_recv_frames:` The number of simultaneous receive transfers
+- `send_frame_size:` The size of a single send transfers in bytes
+- `num_send_frames:` The number of simultaneous send transfers
+
+\subsection transport_usb_udev Setup Udev for USB (Linux)
+
+On Linux, Udev handles USB plug and unplug events. The following
+commands install a Udev rule so that non-root users may access the
+device:
+
+ cd <install-path>/lib/uhd/utils
+ sudo cp uhd-usrp.rules /etc/udev/rules.d/
+ sudo udevadm control --reload-rules
+ sudo udevadm trigger
+
+\subsection transport_usb_installwin Install USB driver (Windows)
+
+A driver package must be installed to use a USB-based product with UHD
+software:
+
+- Download the driver from the UHD wiki page
+ <a href="http://files.ettus.com/binaries/misc/erllc_uhd_winusb_driver.zip">here</a>.
+- Unzip the file into a known location. We will refer to this as the `<directory>`.
+- Open the device manager and plug in the USRP device. You will see an

+ usrp_n2xx_simple_net_burner --addr=<IP address> --fw=<firmware path> --fpga=<FPGA path>
+
+<b>Note:</b> Different hardware revisions require different FPGA images.
+Determine the revision number from the sticker on the rear of the
+chassis. Use this number to select the correct FPGA image for your
+device.
+
+For users who would prefer a graphical utility, a Python-based
+alternative exists.
+
+\subsection usrp2_loadflash_gui Use the graphical net burner tool (Linux)
+
+ <install-path>/lib/uhd/utils/usrp_n2xx_net_burner_gui.py
+
+\subsection usrp2_loadflash_guiwin Use the graphical net burner tool (Windows)
+
+ <path_to_python.exe> <install-path>/lib/uhd/utils/usrp_n2xx_net_burner_gui.py
+
+\subsection usrp2_loadflash_brick Device recovery and bricking
+
+Its possible to put the device into an unusable state by loading bad
+images. Fortunately, the USRP-N Series can be booted into a safe
+(read-only) image. Once booted into the safe image, the user can once
+again load images onto the device.
+
+The safe-mode button is a pushbutton switch (S2) located inside the
+enclosure. To boot into the safe image, hold-down the safe-mode button
+while power-cycling the device. Continue to hold-down the button until
+the front-panel LEDs blink and remain solid.
+
+When in safe-mode, the USRP-N device will always have the IP address **192.168.10.2**.
+
+\section usrp2_network Setup Networking
+
+The USRP2 only supports Gigabit Ethernet and will not work with a 10/100
+Mbps interface. However, a 10/100 Mbps interface can be connected
+indirectly to a USRP2 through a Gigabit Ethernet switch.
+
+\subsection usrp2_network_setuphost Setup the host interface
+
+The USRP2 communicates at the IP/UDP layer over the gigabit ethernet.
+The default IP address of the USRP2 is **192.168.10.2**. You will need
+to configure the host's Ethernet interface with a static IP address to
+enable communication. An address of **192.168.10.1** and a subnet mask
+of **255.255.255.0** is recommended.
+
+On a Linux system, you can set a static IP address very easily by using
+the 'ifconfig' command:
+
+ sudo ifconfig <interface> 192.168.10.1
+
+Note that `interface` is usually something like **eth0**. You can
+discover the names of the network interfaces in your computer by running **ifconfig**
+without any parameters:
+
+ ifconfig -a
+
+<b>Note:</b> When using UHD software, if an IP address for the USRP2 is not
+specified, the software will use UDP broadcast packets to locate the
+USRP2. On some systems, the firewall will block UDP broadcast packets.
+It is recommended that you change or disable your firewall settings.
+
+\subsection usrp2_network_multidev Multiple devices per host
+
+For maximum throughput, one Ethernet interface per USRP2 is recommended,
+although multiple devices may be connected via a Gigabit Ethernet
+switch. In any case, each Ethernet interface should have its own subnet,
+and the corresponding USRP2 device should be assigned an address in that
+subnet. Example:
+
+- Configuration for USRP2 device 0:
+ - Ethernet interface IPv4 address: **192.168.10.1**
+ - Ethernet interface subnet mask: **255.255.255.0**
+ - USRP2 device IPv4 address: **192.168.10.2**
+
+- Configuration for USRP2 device 1:
+ - Ethernet interface IPv4 address: **192.168.20.1**
+ - Ethernet interface subnet mask: **255.255.255.0**
+ - USRP2 device IPv4 address: **192.168.20.2**
+
+\subsection usrp2_network_changeip Change the USRP2's IP address
+
+You may need to change the USRP2's IP address for several reasons:
+- to satisfy your particular network configuration
+- to use multiple USRP2s on the same host computer
+- to set a known IP address into USRP2 (in case you forgot)
+
+#### Method 1
+
+To change the USRP2's IP address, you must know the
+current address of the USRP2, and the network must be setup properly as
+described above. Run the following commands: :
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="ip-addr=192.168.10.3"
+
+#### Method 2 (Linux Only)
+
+This method assumes that you do not know the
+IP address of your USRP2. It uses raw Ethernet packets to bypass the
+IP/UDP layer to communicate with the USRP2. Run the following commands:
+
+ cd <install-path>/lib/uhd/utils
+ sudo ./usrp2_recovery.py --ifc=eth0 --new-ip=192.168.10.3
+
+\section usrp2_commprob Communication Problems
+
+When setting up a development machine for the first time, you may have
+various difficulties communicating with the USRP device. The following
+tips are designed to help narrow down and diagnose the problem.
+
+\subsection usrp2_commprob_ctrlresponse RuntimeError: no control response
+
+This is a common error that occurs when you have set the subnet of your
+network interface to a different subnet than the network interface of
+the USRP device. For example, if your network interface is set to **192.168.20.1**,
+and the USRP device is **192.168.10.2** (note the
+difference in the third numbers of the IP addresses), you will likely
+see a 'no control response' error message.
+
+Fixing this is simple - just set the your host PC's IP address to the
+same subnet as that of your USRP device. Instructions for setting your
+IP address are in the previous section of this documentation.
+
+\subsection usrp2_commprob_firewall Firewall issues
+
+When the IP address is not specified, the device discovery broadcasts
+UDP packets from each ethernet interface. Many firewalls will block the
+replies to these broadcast packets. If disabling your system's firewall
+or specifying the IP address yields a discovered device, then your
+firewall may be blocking replies to UDP broadcast packets. If this is
+the case, we recommend that you disable the firewall or create a rule to
+allow all incoming packets with UDP source port **49152**.
+
+\subsection usrp2_commprob_ping Ping the device
+
+The USRP device will reply to ICMP echo requests. A successful ping
+response means that the device has booted properly and that it is using
+the expected IP address.
+
+ ping 192.168.10.2
+
+\subsection usrp2_commprob_uart Monitor the serial output
+
+Read the serial port to get debug verbose output from the embedded
+microcontroller. The microcontroller prints useful information about IP
+addresses, MAC addresses, control packets, fast-path settings, and
+bootloading. Use a standard USB to 3.3v-level serial converter at 230400
+baud. Connect **GND** to the converter ground, and connect **TXD** to
+the converter receive. The **RXD** pin can be left unconnected as this
+is only a one-way communication.
+
+- **USRP2:** Serial port located on the rear edge
+- **N210:** Serial port located on the left side
+
+\subsection usrp2_commprob_wireshark Monitor the host network traffic
+
+Use Wireshark to monitor packets sent to and received from the device.
+
+\section usrp2_addr Addressing the Device
+
+\subsection usrp2_addr_single Single device configuration
+
+In a single-device configuration, the USRP device must have a unique
+IPv4 address on the host computer. The USRP can be identified through
+its IPv4 address, resolvable hostname, or by other means. See the
+application notes on \ref page_identification.
+Please note that this addressing scheme should also be used with the **multi_usrp**
+interface.
+
+Example device address string representation for a USRP2 with IPv4
+address **192.168.10.2**:
+
+ addr=192.168.10.2
+
+\subsection usrp2_ Multiple device configuration
+
+In a multi-device configuration, each USRP device must have a unique
+IPv4 address on the host computer. The device address parameter keys
+must be suffixed with the device index. Each parameter key should be of
+the format \<key\>\<index\>. Use this addressing scheme with the uhd::usrp::multi_usrp
+interface.
+
+- The order in which devices are indexed corresponds to the indexing
+ of the transmit and receive channels.
+- The key indexing provides the same granularity of device
+ identification as in the single device case.
+
+Example device address string representation for 2 USRP2s with IPv4
+addresses **192.168.10.2** and **192.168.20.2**:
+
+ addr0=192.168.10.2, addr1=192.168.20.2
+
+\section usrp2_mimocable Using the MIMO Cable
+
+The MIMO cable allows two USRP devices to share reference clocks, time
+synchronization, and the Ethernet interface. One of the devices will
+sync its clock and time references to the MIMO cable. This device will
+be referred to as the slave, and the other device, the master.
+
+- The slave device acquires the clock and time references from the
+ master device.
+- The master and slave may be used individually or in a multi-device
+ configuration.
+- External clocking is optional and should only be supplied to the
+ master device.
+
+\subsection usrp2_mimocable_shared Shared Ethernet mode
+
+In shared Ethernet mode, only one device in the configuration can be
+attached to the Ethernet.
+
+- Clock reference, time reference, and data are communicated over the
+ MIMO cable.
+- Master and slave must have different IPv4 addresses in the same
+ subnet.
+
+\subsection usrp2_mimocable_dual Dual Ethernet mode
+
+In dual Ethernet mode, both devices in the configuration must be
+attached to the Ethernet.
+
+- Only clock reference and time reference are communicated over the
+ MIMO cable.
+- The master and slave must have different IPv4 addresses in different
+ subnets.
+
+\subsection usrp2_mimocable_cfgslave Configuring the slave
+
+In order for the slave to synchronize to the master over MIMO cable, the
+following clock configuration must be set on the slave device: :
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->set_time_source("mimo", slave_index);
+ usrp->set_clock_source("mimo", slave_index);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+\section usrp2_altstream Alternative stream destination
+
+It is possible to program the USRP device to send RX packets to an
+alternative IP/UDP destination.
+
+\subsection usrp2_altstream_subnet Set the subnet and gateway
+
+To use an alternative streaming destination, the device needs to be able
+to determine if the destination address is within its subnet, and ARP
+appropriately. Therefore, the user should ensure that subnet and gateway
+addresses have been programmed into the device's EEPROM.
+
+Run the following commands:
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="subnet=255.255.255.0, gateway=192.168.10.2"
+
+\subsection usrp2_altstream_rxstream Create a receive streamer
+
+Set the stream args "addr" and "port" values to the alternative
+destination. Packets will be sent to this destination when the user
+issues a stream command.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ //create a receive streamer, host type does not matter
+ uhd::stream_args_t stream_args("fc32");
+
+ //resolvable address and port for a remote udp socket
+ stream_args.args["addr"] = "192.168.10.42";
+ stream_args.args["port"] = "12345";
+
+ //create the streamer
+ uhd::rx_streamer::sptr rx_stream = usrp->get_rx_stream(stream_args);
+
+ //issue stream command
+ uhd::stream_cmd_t stream_cmd(uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_DONE);
+ stream_cmd.num_samps = total_num_samps;
+ stream_cmd.stream_now = true;
+ usrp->issue_stream_cmd(stream_cmd);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+<b>Note:</b> Calling `recv()` on this streamer object should yield a timeout.
+
+\section usrp2_hw Hardware Setup Notes
+
+\subsection usrp2_hw_leds Front panel LEDs
+
+The LEDs on the front panel can be useful in debugging hardware and
+software issues. The LEDs reveal the following about the state of the
+device:
+
+- **LED A:** transmitting
+- **LED B:** MIMO cable link
+- **LED C:** receiving
+- **LED D:** firmware loaded
+- **LED E:** reference lock
+- **LED F:** CPLD loaded
+
+\subsection usrp2_hw_refclk Ref Clock - 10 MHz
+
+Using an external 10 MHz reference clock, a square wave will offer the
+best phase noise performance, but a sinusoid is acceptable. The
+reference clock requires the following power level:
+
+- **USRP2** 5 to 15 dBm
+- **N2XX** 0 to 15 dBm
+
+\subsection usrp2_hw_pps PPS - Pulse Per Second
+
+Using a PPS signal for timestamp synchronization requires a square wave
+signal with the following amplitude:
+
+- **USRP2** 5Vpp
+- **N2XX** 3.3 to 5Vpp
+
+Test the PPS input with the following app:
+
+- `<args>` are device address arguments (optional if only one USRP
+ device is on your machine)
+
+ cd <install-path>/lib/uhd/examples
+ ./test_pps_input --args=\<args\>
+
+\subsection usrp2_hw_gpsdo Internal GPSDO
+
+Please see \ref page_gpsdo for information on configuring and using the internal GPSDO.
+
+\section usrp2_misc Miscellaneous
+
+\subsection usrp2_misc_sensors Available Sensors
+
+The following sensors are available for the USRP2/N-Series motherboards;
+they can be queried through the API.
+
+- **mimo_locked** - clock reference locked over the MIMO cable
+- **ref_locked** - clock reference locked (internal/external)
+- other sensors are added when the GPSDO is enabled
+
+\subsection usrp2_misc_multirx Multiple RX channels
+
+There are two complete DDC chains in the FPGA. In the single channel
+case, only one chain is ever used. To receive from both channels, the
+user must set the **RX** subdevice specification. This hardware has only
+one daughterboard slot, which has been aptly named slot **A**.
+
+In the following example, a TVRX2 is installed. Channel 0 is sourced
+from subdevice **RX1**, and channel 1 is sourced from subdevice **RX2**
+(**RX1** and **RX2** are the antenna ports on the TVRX2 daughterboard):
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
+ usrp->set_rx_subdev_spec("A:RX1 A:RX2");
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+\section b200_mcr Changing the Master Clock Rate
+
+The master clock rate feeds the RF frontends and the DSP chains. Users
+may select non-default clock rates to acheive integer decimations or
+interpolations in the DSP chains. The default master clock rate defaults
+to 32 MHz, but can be set to any rate between 5 MHz and 61.44 MHz.
+
+The user can set the master clock rate through the usrp API call
+uhd::usrp::multi_usrp::set_master_clock_rate(), or the clock rate can be set through the
+device arguments, which many applications take: :
+
+ uhd_usrp_probe --args="master_clock_rate=52e6"
+
+\section b200_fe RF Frontend Notes
+
+The B200 features an integrated RF frontend.
+
+\subsection b200_fe_tuning Frontend tuning
+
+The RF frontend has individually tunable receive and transmit chains. On
+the B200, there is one transmit and one receive RF frontend. On the
+B210, both transmit and receive can be used in a MIMO configuration. For
+the MIMO case, both receive frontends share the RX LO, and both transmit
+frontends share the TX LO. Each LO is tunable between 50 MHz and 6 GHz.
+
+\subsection b200_fe_gain Frontend gain
+
+All frontends have individual analog gain controls. The receive
+frontends have 73 dB of available gain; and the transmit frontends have
+89.5 dB of available gain. Gain settings are application specific, but
+it is recommended that users consider using at least half of the
+available gain to get reasonable dynamic range.

-Changing the Master Clock Rate
-------------------------------------------------------------------------
-The master clock rate feeds the RF frontends and the DSP chains.
-Users may select non-default clock rates to acheive integer decimations or interpolations in the DSP chains.
-The default master clock rate defaults to 32 MHz, but can be set to any rate between 5 MHz and 61.44 MHz.
-
-The user can set the master clock rate through the usrp API call set_master_clock_rate(),
-or the clock rate can be set through the device arguments, which many applications take:
-::
-
- uhd_usrp_probe --args="master_clock_rate=52e6"

-RF Frontend Notes
-------------------------------------------------------------------------
-The B200 features and integrated RF frontend.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Frontend tuning
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-The RF frontend has individually tunable receive and transmit chains.
-On the B200, there is one transmit and one receive RF frontend.
-On the B210, both transmit and receive can be used in a MIMO configuration.
-For the MIMO case, both receive frontends share the RX LO,
-and both transmit frontends share the TX LO.
-Each LO is tunable between 50 MHz and 6 GHz.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Frontend gain
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-All frontends have individual analog gain controls.
-The receive frontends have 73 dB of available gain;
-and the transmit frontends have 89.5 dB of available gain.
-Gain settings are application specific,
-but it is recommended that users consider using at least
-half of the available gain to get reasonable dynamic range.

+
+UHD software will automatically select the USRP-Embedded FPGA image from
+the installed images package. The FPGA image selection can be overridden
+with the `fpga` device address parameter.
+
+Example device address string representations to specify non-standard
+FPGA image:
+
+ fpga=usrp_e100_custom.bin
+
+\section e1x0_mcr Changing the Master Clock Rate
+
+The master clock rate of the USRP-Embedded feeds both the FPGA DSP and
+the codec chip. Hundreds of rates between 32 MHz and 64 MHz are
+available. A few notable rates are:
+
+- **64 MHz:** maximum rate of the codec chip
+- **61.44 MHz:** good for UMTS/WCDMA applications
+- **52 MHz:** good for GSM applications
+
+\subsection e1x0_mcr_extvcxo Set 61.44MHz - uses external VCXO
+
+To use the 61.44 MHz clock rate with the USRP-Embedded, two jumpers must
+be moved on the device.
+
+- **J16** is a two pin header; remove the jumper (or leave it on pin1
+ only).
+- **J15** is a three pin header; move the jumper to (pin1, pin2).
+
+**Note:** See instructions below to communicate the desired clock rate
+to UHD software.
+
+\subsection e1x0_intvco Set other rates - uses internal VCO
+
+To use other clock rates, the jumpers will need to be in the default
+position.
+
+- **J16** is a two pin header; move the jumper to (pin1, pin2).
+- **J15** is a three pin header; move the jumper to (pin2, pin3).
+
+To communicate the desired clock rate into UHD software, specify the a

+- **Power level:** 0 to 15dBm
+- Select `REF_SMA` in uhd::clock_config_t.
+
+\subsection e1x0_clksync_pps PPS - Pulse Per Second
+
+An external PPS signal for timestamp synchronization can be supplied by
+soldering a connector.
+
+- Connector **J13** (PPS) needs MCX connector **WM5541-ND** or
+ similar.
+- Requires a square wave signal.
+- **Amplitude:** 3.3 to 5 Vpp
+
+Test the PPS input with the following app (`<args>` are device

+
+\section x3x0_getting_started Getting started
+
+This will run you through the first steps relevant to get your USRP X300/X310
+up and running. Here, we assume you will connect your USRP using Gigabit Ethernet (1GigE),
+as this interface is readily available in most computers. For 10 Gigabit Ethernet (10GigE) or
+PCI Express (PCIe), see the corresponding sections in this manual page.
+
+\subsection x3x0_getting_started_assembling Assembling the X300/X310 kit
+
+Before you can start using your USRP, you might have to assemble the hardware,
+if this has not yet happened. Make sure you are grounded (e.g. by touching a radiator)
+in order not to damage sensitive electronics through static discharge!
+
+1. Unscrew the top of your X300/X310 (there are 2 screws which can be easily loosened
+ using a small Phillips screwdriver).
+2. Insert the daughterboards by inserting them into the slots and optionally screwing
+ them onto the motherboard.
+3. Connect the RF connectors on the daughterboards to the front panel. In order to avoid
+ confusion, make sure the internal connections match the labels on the front panel (i.e.
+ TX/RX is connected to TX/RX).
+4. If you have purchased an internal GPSDO, follow the instructions on
+ \ref page_gpsdo_x3x0 to insert the GPSDO. Note that you
+ will need an external GPS antenna connected to the rear GPS ANT connector in order to
+ make use of GPS, although your USRP will still be usable without.
+5. Connect the 1 GigE SFP+ transceiver into the Ethernet port 0 and connect the X300/X310 with
+ your computer.
+6. Connect the power supply and switch on the USRP.
+
+\subsection x3x0_getting_started_connectivity Network Connectivity
+
+The next step is to make sure your computer can talk to the USRP. An otherwise unconfigured
+USRP device will have the IP address 192.168.10.2 when using 1GigE.
+It is recommended to directly connect your USRP to the computer at first,
+and to set the IP address on your machine to 192.168.10.1.
+See \ref x3x0_setup_network_host_interface on details how to change your machine's IP address.
+
+<b>Note</b>: If you are running an automatic IP configuration service such as Network Manager, make
+sure it is either deactivated or configured to not change the network device! This can, in extreme cases,
+lead to you bricking the USRP!
+
+If your network configuration is correct, running `uhd_find_devices` will find your USRP
+and print some information about it. You will also be able to ping the USRP by running:
+
+ ping 192.168.10.2
+
+on the command line. At this point, you should also run:
+
+ uhd_usrp_probe --args addr=192.168.10.2
+
+to make sure all of your components (daughterboards, GPSDO) are correctly detected and usable.
+
+\subsection x3x0_getting_started_fpga_update Updating the FPGA
+
+If the output from `uhd_find_devices` and `uhd_usrp_probe` didn't show any warnings, you
+can skip this step. However, if there were errors regarding the FPGA version compatibility
+number, you will have to update the FPGA image before you can start using your USRP.
+
+1. Download the current UHD images. You can use the `uhd_images_downloader` script provided
+ with UHD (see also \ref page_images).
+2. Use the `usrp_x3xx_fpga_burner` utility to update the FPGA image. On the command line, run:
+
+ usrp_x3xx_fpga_burner --addr=192.168.10.2 --type=HGS
+
+ If you have installed the images to a non-standard location, you might need to run (change the filename according to your device):
+
+ usrp_x3xx_fpga_burner --addr=192.168.10.2 --fpga-path <path_to_images>/usrp_x310_fpga_HGS.bit
+
+ The process of updating the FPGA image will take several minutes. Make sure the process of flashing the image does not get interrupted.
+
+See \ref x3x0_flash for more details.
+
+When your FPGA is up to date, power-cycle the device and re-run `uhd_usrp_probe`. There should
+be no more warnings at this point, and all components should be correctly detected. Your USRP is now
+ready for development!
+
+\section x3x0_hw Hardware Setup
+
+\subsection x3x0_hw_1gige Gigabit Ethernet (1 GigE)
+
+- Prior to installing the module, the host PC can remain powered on.
+- Plug a 1 Gigabit SFP Transceiver into Ethernet Port 0 on the USRP X300/X310 device.
+- Use the Ethernet cable to connect the SFP+ transciever on the device to the host computer. For maximum throughput, Ettus Research recommends that you connect each device to its own dedicated Gigabit Ethernet interface on the host computer.
+- Connect the AC/DC power supply to the device and plug the supply into a wall outlet.
+- The OS will automatically recognize the device (e.g. when running `uhd_find_devices`).
+

+Ettus Research recommends the Intel Ethernet Converged Network Adapter X520-DA2 interface for communication with the USRP X300/X310 device.
+Installation instructions for this interface are available on the official Intel website.
+
+### Installing the USRP X300/X310
+
+- Prior to installing the module, the host PC can remain powered on.
+- Use a 10 Gigabit SFP+ cable to connect Ethernet Port 1 on the USRP X300/X310 device to the host computer. For maximum throughput, Ettus Research recommends that you connect the device to its own dedicated Ten Gigabit, Ettus Research recommended Ethernet interface on the host computer.
+- Connect the AC/DC power supply to the device and plug the supply into a wall outlet.
+- The OS will automatically recognize the device (e.g. when running `uhd_find_devices`).
+
+The LEDs on the front panel can be useful in debugging hardware and software issues (see \ref x3x0_hw_fpanel)
+

+
+<b>Important Note: The USRP X-Series provides PCIe connectivity over MXI cable.
+We will use the 'MXI' nomenclature for the rest of this manual.</b>
+
+### Installing the PCI Express Interface Kit
+
+Follow the instructions listed in the <a href="http://www.ni.com/pdf/manuals/371976c.pdf">Set Up Your MXI-Express x4 System</a>
+document to setup the NI PCIe-8371 module.
+
+### Installing the USRP X300/X310
+
+- Prior to installing the module, make sure that the PC is powered off.
+- Using a MXI-Express Cable connect the USRP X300/X310 to the NI PCIe-8371.
+- Connect the AC/DC power supply to the device and plug the supply into a wall outlet.
+- Power on the USRP X300/X310 device using the power switch located in the bottom-right corner of the front panel.
+- Power on the PC (The OS automatically recognizes the new device)
+
+<b>Note:</b> The USRP device is not hot-pluggable over PCI Express. Any connection changes with only be detected by your
+computer after a successful reboot.
+
+### Troubleshooting
+
+Two possible failure modes are your computer not booting when connected to your
+USRP device through MXI-Express, and Windows not properly discovering your
+devices (for example, there is a yellow exclamation point on a PCI to PCI
+bridge in Windows Device Manager, despite drivers for all devices being
+installed). These situations often are due to programming errors in PCI Express
+device configuration of the BIOS. To use this software, you need a MXI-Express
+device that supports Mode 1 operation.
+Refer to <a href="http://download.ni.com/support/softlib//PXI/MXIe%20Compatibility%20Software/1.5.0/readme.html#SupportedHardware">NI MXI-Express BIOS Compatibility Software Readme</a>
+for more information.
+
+The BIOS Compatibility Software can be downloaded for Windows from the <a href="http://www.ni.com/download/mxi-express-bios-compatibility-software-1.5/3764/en/"> MXI-Express BIOS Compatibility Software page</a>.

+\subsection x3x0_hw_pcie_laptop PCI Express (Laptop)
+
+<b>Important Note: The USRP X-Series provides PCIe connectivity over MXI cable
+We will use the 'MXI' nomenclature for the rest of this manual.</b>
+
+### Installing the PCI Express Card
+
+Follow the instructions listed in the “Installing an NI ExpressCard-8360 Host Card†section of the
+<a href="http://www.ni.com/pdf/manuals/373259d.pdf#page=10">Set Up Your MXI-Express x1 System</a>
+document to setup the NI ExpressCard-8360B module.
+
+### Installing the USRP X300/X310
+
+Because a laptop computer is not grounded, follow this procedure to safely connect a laptop
+computer to your USRP device.
+
+- Connect the AC/DC power supply to the device and plug the supply into a wall outlet. Ensure that the USRP device is powered off.
+- Touch the NI ExpressCard-8360B and a metal part of the USRP device simultaneously. Do not install the NI ExpressCard-8360B into the laptop computer yet.
+- Connect the cable to the NI ExpressCard-8360B and USRP.
+- Plug the NI ExpressCard-8360B into an available ExpressCard slot. If your laptop computer is already running (or hibernating, suspended, etc.) when you install an NI ExpressCard-8360B, you must reboot to detect the USRP. Otherwise, the USRP is detected when you start your computer.
+
+\b Note: The USRP device is not hot-pluggable over PCI Express. Any connection changes will only be detected by your computer after a successful reboot.
+
+\section x3x0_jtag On-Board JTAG Programmer
+
+The USRP X3x0 includes an on-board JTAG programmer, built into the motherboard.
+To connect to this JTAG device, simply connect your computer to the USB JTAG
+port on the front of the X3x0 device. You may now use the JTAG programmer in
+the same way you would use any other, including:
+
+- <a href="http://www.xilinx.com/support/download/index.htm">Xilinx Programming Tools (ISE, iMPACT)</a>
+- <a href="http://www.xilinx.com/tools/cspro.htm">Xilinx Chipscope</a>
+- <a href="https://www.digilentinc.com/Products/Detail.cfm?NavPath=2,66,828&Prod=ADEPT2">Digilent ADEPT</a>
+
+In order to use the JTAG programmer with the Xilinx tools, the Digilent drivers and plugin have to be installed first.
+Although recent versions of ISE ship with the driver, it has to still be manually installed.
+
+\b Note: Sometimes the ISE shipped versions are newer than the ones available via Digilent's website. It is therefore advisable to
+use the ISE provided plugin and drivers.
+
+To install first locate your ISE installation path on a Linux system (default is `/opt/Xilinx/<Version>`):
+
+ sudo <ise install path>/ISE_DS/common/bin/lin64/digilent/install_digilent.sh
+
+Afterwards either reboot or force udev to reload its rules by:
+
+ sudo udevadm control --reload
+
+The USRP-X series device should now be usable with all the tools mentioned above.
+
+\section x3x0_load_fpga_imgs Load FPGA Images onto the Device
+
+The USRP-X Series device ships with a bitstream pre-programmed in the flash,
+which is automatically loaded onto the FPGA during device power-up. However,
+a new FPGA image can be configured over the PCI Express interface or the
+on-board USB-JTAG programmer. This process can be seen as a "one-time load", in
+that if you power-cycle the device, it will not retain the FPGA image.
+
+Please note that this process is *different* than replacing the FPGA image
+stored in the flash, which will then be automatically loaded the next time the
+device is reset.
+
+\subsection x3x0_load_fpga_imgs_fpga_flavours FPGA Image Flavors
+
+The USRP-X Series devices contains two SFP+ ports for the two Ethernet channels.
+Because the SFP+ ports support both 1 Gigabit (SFP) and 10 Gigabit (SFP+)
+transceivers, several FPGA images are shipped with UHD to determine the
+behavior of the above interfaces.
+
+|  FPGA Image Flavor  |  SFP+ Port 0 Interface |  SFP+ Port 1 Interface |
+|---------------------|------------------------|------------------------|
+|  HGS (Default)  |  1 Gigabit Ethernet |  10 Gigabit Ethernet   |
+|  XGS   |  10 Gigabit Ethernet |  10 Gigabit Ethernet   |
+
+FPGA images are shipped in 2 formats:
+
+- **LVBITX**: LabVIEW FPGA configuration bitstream format (for use over PCI Express and Ethernet)
+- **BIT**: Xilinx configuration bitstream format (for use over Ethernet and JTAG)
+
+To get the latest images, simply use the uhd_images_downloader script. On Unix systems, use this command:
+
+ sudo uhd_images_downloader
+
+On Windows, use:
+
+ <path_to_python.exe> <install-path>/bin/uhd_images_downloader.py
+
+
+\subsection x3x0_load_fpga_imgs_pcie Use PCI Express to load FPGA images
+
+UHD requires a valid LabVIEW FPGA configuration bitstream file (LVBITX) to use the USRP-X Series
+device over the PCI Express bus. LabVIEW FPGA is \b not required to use UHD with a USRP-X Series device.
+Because FPGA configuration is a part of normal operation over PCI Express, there is no setup required
+before running UHD.
+
+The \e fpga tag can be set in the optional device args passed to indicate the FPGA image flavor to UHD.
+If the above tag is specified, UHD will attempt to load the FPGA image with the requested flavor from the
+UHD images directory. If the tag is not specified, UHD will automatically detect the flavor of the image
+and attempt to load the corresponding configuration bitstream onto the device. Note that if UHD detects
+that the requested image is already loaded onto the FPGA then it will not reload it.
+
+\subsection x3x0_load_fpga_imgs_jtag Use JTAG to load FPGA images
+
+The USRP-X Series device features an on-board USB-JTAG programmer that can be accessed on the front-panel
+of the device. The iMPACT tool in the <a href="http://www.xilinx.com/support/download/index.htm">Xilinx Programming Tools (ISE, iMPACT)</a> package can be used to load an image over the JTAG interface. This can be useful for unbricking devices.
+
+If you have iMPACT installed, you can use the `impact_jtag_programmer.sh` tool to install images. Make sure your X3x0 is powered on and connected to your computer using the front panel USB JTAG connector (USB 2.0 is fine for this). Then run the tool:
+
+ <path_to_uhd_tools>/impact_jtag_programmer.sh --fpga-path=<fpga_image_path>
+
+\section x3x0_flash Load the Images onto the On-board Flash
+
+To change the FPGA image stored in the on-board flash, the USRP-X Series device
+can be reprogrammed over the network or PCI Express. Once you have programmed an
+image into the flash, that image will be automatically loaded on the FPGA
+during the device boot-up sequence.
+
+\b Note:
+Different hardware revisions require different FPGA images.
+Determine the revision number from the sticker on the rear of the device.
+If you are manually specifying an FPGA path, the utility will not try to
+detect your device information, and you will need to use this number to
+select which image to burn.
+
+\b Note:
+The burner utility will default to using the appropriate BIT file if no custom
+FPGA image path is specified, but it is compatible with BIN, BIT, and LVBITX
+images.
+
+\subsection x3x0_flash_burner_tool Use the burner tool over Ethernet
+
+ Automatic FPGA path, detect image type:
+ usrp_x3xx_fpga_burner --addr=<IP address>
+
+ Automatic FPGA path, select image type:
+ usrp_x3xx_fpga_burner --addr=<IP address> --type=<HGS or XGS>
+
+ Manual FPGA path:
+ usrp_x3xx_fpga_burner --addr=<IP address> --fpga-path=<path to FPGA image>
+
+\subsection x3x0_flash_burner_tool_pcie Use the burner tool over PCI Express
+
+ Automatic FPGA path, detect image type:
+ usrp_x3xx_fpga_burner --resource=<NI-RIO resource>
+
+ Automatic FPGA path, select image type:
+ usrp_x3xx_fpga_burner --resource=<NI-RIO resource> --type=<HGS or XGS>
+
+ Manual FPGA path:
+ usrp_x3xx_fpga_burner --resource=<NI-RIO resource> --fpga-path=<path to FPGA image>
+
+\subsection x3x0_flash_bricking Device recovery and bricking
+It is possible to put the device into an unusable state by loading bad images ("bricking").
+Fortunately, the USRP-X Series device can be loaded with a good image temporarily using the USB-JTAG interface.
+Once booted into the safe image, the user can once again load images onto the device over Ethernet or PCI Express.
+
+\section x3x0_setup_network Setup Networking
+The USRP-X Series only supports Gigabit and Ten Gigabit Ethernet and will not work with a 10/100 Mbps interface.
+
+<b>Please note that 10 Gigabit Ethernet defines the protocol, not necessary the
+medium. For example, you may use 10GigE over optical with optical SFP+
+transceiver modules.</b>
+
+\subsection x3x0_setup_network_host_interface Setup the host interface
+
+The USRP-X Series communicates at the IP/UDP layer over the Gigabit and Ten Gigabit Ethernet.
+The default IP address for the USRP X300/X310 device depends on the Ethernet Port and interface used.
+You must configure the host Ethernet interface with a static IP address on the same subnet as the connected
+device to enable communication, as shown in the following table:
+
+  Ethernet Interface | USRP Ethernet Port |  Default USRP IP Address |  Host Static IP Address | Host Static Subnet Mask | Address EEPROM key
+---------------------|-------------------------|--------------------------|-------------------------|-------------------------|-------------------
+  Gigabit  |  Port 0 (HGS Image) |  192.168.10.2 | 192.168.10.1 | 255.255.255.0 | `ip-addr0`
+  Ten Gigabit  |  Port 0 (XGS Image) |  192.168.30.2 | 192.168.30.1 | 255.255.255.0 | `ip-addr2`
+  Ten Gigabit  |  Port 1 (HGS/XGS Image) |  192.168.40.2 | 192.168.40.1 | 255.255.255.0 | `ip-addr3`
+
+As you can see, the X300/X310 actually stores different IP addresses, which all address the device differently: Each combination of Ethernet port and interface type (i.e., Gigabit or Ten Gigabit) has its own IP address. As an example, when addressing the device through 1 Gigabit Ethernet on its first port (Port 0), the relevant IP address is the one stored in the EEPROM with key `ip-addr0`, or 192.168.10.2 by default.
+
+See \ref x3x0cfg_hostpc_netcfg_ip on details how to change your machine's IP address and MTU size to work well with the X300.
+
+\subsection x3x0_setup_network_multidevs Multiple devices per host
+
+For maximum throughput, one Ethernet interface per USRP is recommended,
+although multiple devices may be connected via an Ethernet switch.
+In any case, each Ethernet interface should have its own subnet,
+and the corresponding USRP device should be assigned an address in that subnet.
+Example:
+
+### Configuration for USRP-X Series device 0:
+
+- Ethernet interface IPv4 address: `192.168.10.1`
+- Ethernet interface subnet mask: `255.255.255.0`
+- USRP-X Series device IPv4 address: `192.168.10.2`
+
+### Configuration for USRP-X Series device 1:
+
+- Ethernet interface IPv4 address: `192.168.110.1`
+- Ethernet interface subnet mask: `255.255.255.0`
+- USRP-X Series device IPv4 address: `192.168.110.2`
+
+\subsection x3x0_setup_change_ip Change the USRP's IP address
+
+You may need to change the USRP's IP address for several reasons:
+- to satisfy your particular network configuration
+- to use multiple USRP-X Series devices on the same host computer
+- to set a known IP address into USRP (in case you forgot)
+
+To change the USRP's IP address,
+you must know the current address of the USRP,
+and the network must be setup properly as described above.
+You must also know which IP address of the X300 you want to change, as identified by their address EEPROM key (e.g. `ip-addr0`, see the table above).
+Run the following commands:
+
+\b UNIX:
+
+ cd <install-path>/lib/uhd/utils
+ ./usrp_burn_mb_eeprom --args=<optional device args> --values="ip-addr0=192.168.10.3"
+
+\b Windows:
+
+ cd <install-path>\lib\uhd\utils
+ usrp_burn_mb_eeprom.exe --args=<optional device args> --values="ip-addr0=192.168.10.3"
+
+You must power-cycle the device before you can use this new address.
+
+\section x3x0_addressing Addressing the Device
+
+\subsection x3x0_addressing_singledev Single device configuration
+
+In a single-device configuration,
+the USRP device must have a unique IPv4 address on the host computer.
+The USRP can be identified through its IPv4 address, resolvable hostname, NI-RIO resource name or by other means.
+See the application notes on \ref page_identification.
+Use this addressing scheme with the uhd::usrp::multi_usrp interface (not a typo!).
+
+Example device address string representation for a USRP-X Series device with IPv4 address 192.168.10.2:
+
+ addr=192.168.10.2
+
+Example device address string representation for a USRP-X Series device with RIO resource name `RIO0` over PCI Express:
+
+ resource=RIO0
+
+\subsection x3x0_addressing_multidevcfg Multiple device configuration
+
+In a multi-device configuration,
+each USRP device must have a unique IPv4 address on the host computer.
+The device address parameter keys must be suffixed with the device index.
+Each parameter key should be of the format \<key\>\<index\>.
+Use this addressing scheme with the uhd::usrp::multi_usrp interface.
+
+- The order in which devices are indexed corresponds to the indexing of the transmit and receive channels.
+- The key indexing provides the same granularity of device identification as in the single device case.
+
+Example device address string representation for 2 USRPs with IPv4 addresses **192.168.10.2** and **192.168.20.2**:
+
+ addr0=192.168.10.2, addr1=192.168.20.2
+
+
+\section x3x0_comm_problems Communication Problems
+
+When setting up a development machine for the first time,
+you may have various difficulties communicating with the USRP device.
+The following tips are designed to help narrow down and diagnose the problem.
+
+\subsection x3x0_comm_problems_runtimeerr RuntimeError: no control response
+
+This is a common error that occurs when you have set the subnet of your network
+interface to a different subnet than the network interface of the USRP device. For
+example, if your network interface is set to **192.168.20.1**, and the USRP device is **192.168.10.2**
+(note the difference in the third numbers of the IP addresses), you
+will likely see a 'no control response' error message.
+
+Fixing this is simple - just set the your host PC's IP address to the same
+subnet as that of your USRP device. Instructions for setting your IP address are in the
+previous section of this documentation.
+
+\subsection x3x0_comm_problems_firewall Firewall issues
+
+When the IP address is not specified,
+the device discovery broadcasts UDP packets from each Ethernet interface.
+Many firewalls will block the replies to these broadcast packets.
+If disabling your system's firewall
+or specifying the IP address yields a discovered device,
+then your firewall may be blocking replies to UDP broadcast packets.
+If this is the case, we recommend that you disable the firewall
+or create a rule to allow all incoming packets with UDP source port **49152**.
+
+\subsection x3x0_comm_problems_ping Ping the device
+The USRP device will reply to ICMP echo requests ("ping").
+A successful ping response means that the device has booted properly
+and that it is using the expected IP address.
+
+ ping 192.168.10.2
+
+\subsection x3x0_comm_problems_not_enumerated USRP device not enumerated (Linux)
+
+UHD requires the RIO device manager service to be running in order to
+communicate with an X-Series USRP over PCIe. This service is installed as
+a part of the USRP RIO (or NI-USRP) installer. On Linux, the service is not
+started at system boot time, and is left to the user to control. To start it,
+run the following command:
+
+ sudo niusrprio_pcie start
+
+If the device still does not enumerate after starting the device manager, make sure that the host computer
+has successfully detected it. You can do so by running the following command:
+
+ lspci -k -d 1093:c4c4
+
+A device similar to the following should be detected:
+
+ $ lspci -k -d 1093:c4c4
+ 04:00.0 Signal processing controller: National Instruments ...
+ Subsystem: National Instruments Device 76ca
+ Kernel driver in use: niusrpriok_shipped
+
+- A USRP X300 should appear with 'Subsystem: National Instruments Device 7736'
+- A USRP X310 should appear with 'Subsystem: National Instruments Device 76ca'
+
+\subsection x3x0_comm_problems_not_enumerated_win USRP device not enumerated (Windows)
+
+UHD requires the RIO device manager service to be running in order to
+communicate with an X-Series USRP over PCIe.
+This service is installed as a part of the USRP RIO (or NI-USRP) installer. On Windows, it can be found in
+the **Services** section in the Control Panel and it is started at system boot time. To ensure that the
+service is indeed started, navigate to the Services tag in the Windows Task Manager and ensure that the
+status of **niusrpriorpc** is "Running".
+
+If the device still does not enumerate after starting the device manager, make sure that the host computer
+has successfully detected it. You can do so by checking if your device shows up in the Windows Device Manager.
+
+\subsection x3x0_comm_problems_monitor Monitor the host network traffic
+Use Wireshark to monitor packets sent to and received from the device.
+
+\subsection x3x0_comm_problems_leds Observe Ethernet port LEDs
+When there is network traffic arriving at the Ethernet port, LEDs will light up.
+You can use this to make sure the network connection is correctly set up, e.g.
+by pinging the USRP and making sure the LEDs start to blink.

-Getting started
----------------
-
-This will run you through the first steps relevant to get your USRP X300/X310
-up and running. Here, we assume you will connect your USRP using Gigabit Ethernet (1GigE),
-as this interface is readily available in most computers. For 10 Gigabit Ethernet (10GigE) or
-PCI Express (PCIe), see the corresponding sections in this manual page.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Assembling the X300/X310 kit
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Before you can start using your USRP, you might have to assemble the hardware,
-if this has not yet happened. Make sure you are grounded (e.g. by touching a radiator)
-in order not to damage sensitive electronics through static discharge!
-
-1. Unscrew the top of your X300/X310 (there are 2 screws which can be easily loosened
- using a small Phillips screwdriver).
-2. Insert the daughterboards by inserting them into the slots and optionally screwing
- them onto the motherboard.
-3. Connect the RF connectors on the daughterboards to the front panel. In order to avoid
- confusion, make sure the internal connections match the labels on the front panel (i.e.
- TX/RX is connected to TX/RX).
-4. If you have purchased an internal GPSDO, follow the instructions on
- `the internal GPSDO manual page <./gpsdo_x3x0.html>`_ to insert the GPSDO. Note that you
- will need an external GPS antenna connected to the rear GPS ANT connector in order to
- make use of GPS, although your USRP will still be usable without.
-5. Connect the 1 GigE SFP+ transceiver into the Ethernet port 0 and connect the X300/X310 with
- your computer.
-6. Connect the power supply and switch on the USRP.
-
-^^^^^^^^^^^^^^^^^^^^
-Network Connectivity
-^^^^^^^^^^^^^^^^^^^^
-
-The next step is to make sure your computer can talk to the USRP. An otherwise
-unconfigured USRP device will have the IP address 192.168.10.2 when using
-1GigE. It is recommended to directly connect your USRP to the computer at
-first, and to set the IP address on your machine to 192.168.10.1.
-
-See the `system configuration manual <./usrp_x3x0_config.html>`_ on details how
-to change your machine's IP address.
-
-**Note**: If you are running an automatic IP configuration service such as
-Network Manager, make sure it is either deactivated or configured to not manage
-the network interface! This can, in extreme cases, lead to you bricking the
-USRP!
-
-If your network configuration is correct, running ``uhd_find_devices`` will find your USRP
-and print some information about it. You will also be able to ping the USRP by running::
-
- ping 192.168.10.2
-
-on the command line. At this point, you should also run::
-
- uhd_usrp_probe --args addr=192.168.10.2
-
-to make sure all of your components (daughterboards, GPSDO) are correctly detected and usable.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^
-Updating the FPGA Image
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If the output from ``uhd_find_devices`` and ``uhd_usrp_probe`` didn't show any
-warnings, you can skip this step. However, if there were errors regarding the
-FPGA version compatibility number (compat number), you will have to upate the
-FPGA image before you can start using your USRP.
-
-1. Download the current UHD images. You can use the ``uhd_images_downloader`` script provided
- with UHD (see also `FPGA Image Flavors`_).
-2. Use the ``usrp_x3xx_fpga_burner`` utility to update the FPGA image. On the command line, run::
-
- usrp_x3xx_fpga_burner --addr=192.168.10.2 --type=HGS
-
- If you have installed the images to a non-standard location, you might need to run (change the filename according to your device)::
-
- usrp_x3xx_fpga_burner --addr=192.168.10.2 --fpga-path <path_to_images>/usrp_x310_fpga_HGS.bit
-
- The process of updating the FPGA image will take several minutes. Make sure the process of flashing the image does not get interrupted.
-
-See `Load the Images onto the On-board Flash`_ for more details.
-
-When your FPGA image is up to date, power-cycle the device and re-run
-``uhd_usrp_probe``. There should be no errors at this point, and all components
-should be correctly detected. Your USRP is now ready for development!

-
-Installing the USRP X300/X310
-:::::::::::::::::::::::::::::
-Because a laptop computer is not grounded, follow this procedure to safely connect a laptop
-computer to your USRP device.
-
-* Connect the AC/DC power supply to the device and plug the supply into a wall outlet. Ensure that the USRP device is powered off.
-* Touch the NI ExpressCard-8360B and a metal part of the USRP device simultaneously. Do not install the NI ExpressCard-8360B into the laptop computer yet.
-* Connect the cable to the NI ExpressCard-8360B and USRP.
-* Plug the NI ExpressCard-8360B into an available ExpressCard slot. If your laptop computer is already running (or hibernating, suspended, etc) when you install an NI ExpressCard-8360B, you must reboot to detect the USRP. Otherwise, the USRP is detected when you start your computer.
-
-NOTE: The USRP device is not hot-pluggable over PCI Express. Any connection changes will only be detected by your computer after a successful reboot.
-
---------------------------------
-On-Board JTAG Programmer
---------------------------------
-The USRP X3x0 includes an on-board JTAG programmer, built into the motherboard.
-To connect to this JTAG device, simply connect your computer to the USB JTAG
-port on the front of the X3x0 device. You may now use the JTAG programmer in
-the same way you would use any other, including:
-
-* `Xilinx Programming Tools (ISE, iMPACT) <http://www.xilinx.com/support/download/index.htm>`_
-* `Xilinx Chipscope <http://www.xilinx.com/tools/cspro.htm>`_
-* `Digilent ADEPT <https://www.digilentinc.com/Products/Detail.cfm?NavPath=2,66,828&Prod=ADEPT2>`_
-
-In order to use the JTAG programmer with the Xilinx tools, the Digilent drivers and plugin have to be installed first.
-Although recent versions of ISE ship with the driver, it has to still be manually installed.
-
-Note: Sometimes the ISE shipped versions are newer than the ones available via Digilent's website. It is therefore advisable to
-use the ISE provided plugin and drivers.
-
-To install first locate your ISE installation path (default is /opt/Xilinx/<Version>).
-
-**LINUX**
-::
-
- sudo <ise install path>/ISE_DS/common/bin/lin64/digilent/install_digilent.sh
-
-Afterwards either reboot or force udev to reload its rules by:
-::
-
- sudo udevadm control --reload
-
-The USRP-X series device should now be usable with all the tools mentioned above.
-
---------------------------------
-Load FPGA Images onto the Device
---------------------------------
-The USRP-X Series device ships with a bitstream pre-programmed in the flash,
-which is automatically loaded onto the FPGA during device power-up. However,
-a new FPGA image can be configured over the PCI Express interface or the
-on-board USB-JTAG programmer. This process can be seen as a "one-time load", in
-that if you power-cycle the device, it will not retain the FPGA image.
-
-Please note that this process is *different* than replacing the FPGA image
-stored in the flash, which will then be automatically loaded the next time the
-device is reset.
-
-^^^^^^^^^^^^^^^^^^
-FPGA Image Flavors
-^^^^^^^^^^^^^^^^^^
-The USRP-X Series devices contains two SFP+ ports for the two Ethernet channels.
-Because the SFP+ ports support both 1 Gigabit (SFP) and 10 Gigabit (SFP+)
-transceivers, several FPGA images are shipped with UHD to determine the
-behavior of the above interfaces.
-
-+---------------------+------------------------+------------------------+
-|  FPGA Image Flavor  |  SFP+ Port 0 Interface |  SFP+ Port 1 Interface |
-+=====================+========================+========================+
-|  HGS (Default)  |  1 Gigabit Ethernet |  10 Gigabit Ethernet   |
-+---------------------+------------------------+------------------------+
-|  XGS   |  10 Gigabit Ethernet |  10 Gigabit Ethernet   |
-+---------------------+------------------------+------------------------+
-
-FPGA images are shipped in 2 formats:
-
-* **LVBITX**: LabVIEW FPGA configuration bitstream format (for use over PCI Express and Ethernet)
-* **BIT**: Xilinx configuration bitstream format (for use over Ethernet and JTAG)
-
-To get the latest images, simply use the uhd_images_downloader script:
-
-**UNIX:**
-
-::
-
- sudo uhd_images_downloader
-
-**Windows:**
-
-::
-
- <path_to_python.exe> <install-path>/bin/uhd_images_downloader.py
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Use PCI Express to load FPGA images
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-UHD requires a valid LabVIEW FPGA configuration bitstream file (LVBITX) to use the USRP-X Series
-device over the PCI Express bus. LabVIEW FPGA is **NOT** required to use UHD with a USRP-X Series device.
-Because FPGA configuration is a part of normal operation over PCI Express, there is no setup required
-before running UHD.
-
-The **fpga** tag can be set in the optional device args passed to indicate the FPGA image flavor to UHD.
-If the above tag is specified, UHD will attempt to load the FPGA image with the requested flavor from the
-UHD images directory. If the tag is not specified, UHD will automatically detect the flavor of the image
-and attempt to load the corresponding configuration bitstream onto the device. Note that if UHD detects
-that the requested image is already loaded onto the FPGA then it will not reload it.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Use JTAG to load FPGA images
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-The USRP-X Series device features an on-board USB-JTAG programmer that can be accessed on the front-panel
-of the device. The iMPACT tool in the `Xilinx Programming Tools <http://www.xilinx.com/support/download/index.htm>`_ package can be used to load an image over
-the JTAG interface. This can be useful for unbricking devices.
-
-If you have iMPACT installed, you can use the impact_jtag_programmer.sh tool to install images. Make sure your X3x0 is powered on and connected to your computer using the front panel USB JTAG connector (USB 2.0 is fine for this). Then run the tool:
-
-::
-
- <path_to_uhd_tools>/impact_jtag_programmer.sh --fpga-path=<fpga_image_path>
-
----------------------------------------
-Load the Images onto the On-board Flash
----------------------------------------
-To change the FPGA image stored in the on-board flash, the USRP-X Series device
-can be reprogrammed over the network or PCI Express. Once you have programmed an
-image into the flash, that image will be automatically loaded on the FPGA
-during the device boot-up sequence.
-
-**Note:**
-Different hardware revisions require different FPGA images.
-Determine the revision number from the sticker on the rear of the device.
-If you are manually specifying an FPGA path, the utility will not try to
-detect your device information, and you will need to use this number to
-select which image to burn.
-
-**Note:**
-The burner utility will default to using the appropriate BIT file if no custom
-FPGA image path is specified, but it is compatible with BIN, BIT, and LVBITX
-images.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Use the burner tool over Ethernet
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-
- Automatic FPGA path, detect image type:
- usrp_x3xx_fpga_burner --addr=<IP address>
-
- Automatic FPGA path, select image type:
- usrp_x3xx_fpga_burner --addr=<IP address> --type=<HGS or XGS>
-
- Manual FPGA path:
- usrp_x3xx_fpga_burner --addr=<IP address> --fpga-path=<path to FPGA image>
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Use the burner tool over PCI Express
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-
- Automatic FPGA path, detect image type:
- usrp_x3xx_fpga_burner --resource=<NI-RIO resource>
-
- Automatic FPGA path, select image type:
- usrp_x3xx_fpga_burner --resource=<NI-RIO resource> --type=<HGS or XGS>
-
- Manual FPGA path:
- usrp_x3xx_fpga_burner --resource=<NI-RIO resource> --fpga-path=<path to FPGA image>
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Device recovery and bricking
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-It is possible to put the device into an unusable state by loading bad images ("bricking").
-Fortunately, the USRP-X Series device can be loaded with a good image temporarily using the USB-JTAG interface.
-Once booted into the safe image, the user can once again load images onto the device over Ethernet or PCI Express.
-
-----------------
-Setup Networking
-----------------
-The USRP-X Series only supports Gigabit and Ten Gigabit Ethernet and will not work with a 10/100 Mbps interface.
-
-**Please note that 10 Gigabit Ethernet defines the protocol, not necessary the
-medium. For example, you may use 10GigE over optical with optical SFP+
-transceiver modules.**
-
-^^^^^^^^^^^^^^^^^^^^^^^^
-Setup the host interface
-^^^^^^^^^^^^^^^^^^^^^^^^
-The USRP-X Series communicates at the IP/UDP layer over the Gigabit and Ten Gigabit Ethernet.
-The default IP address for the USRP X300/X310 device depends on the Ethernet Port and interface used.
-You must configure the host Ethernet interface with a static IP address on the same subnet as the connected
-device to enable communication, as shown in the following table:
-
-+---------------+-------------------------+----------------+----------------+---------------+---------------+
-|  Ethernet  | USRP |  Default USRP  |  Host Static   | Host Static | Address |
-| Interface | Ethernet Port | IP Address | IP Address | Subnet Mask | EEPROM key |
-+===============+=========================+================+================+===============+===============+
-|  Gigabit  |  Port 0 (HGS Image) |  192.168.10.2 | 192.168.10.1 | 255.255.255.0 | ``ip-addr0`` |
-+---------------+-------------------------+----------------+----------------+---------------+---------------+
-|  Ten Gigabit  |  Port 0 (XGS Image) |  192.168.30.2 | 192.168.30.1 | 255.255.255.0 | ``ip-addr2`` |
-+---------------+-------------------------+----------------+----------------+---------------+---------------+
-|  Ten Gigabit  |  Port 1 (HGS/XGS Image) |  192.168.40.2 | 192.168.40.1 | 255.255.255.0 | ``ip-addr3`` |
-+---------------+-------------------------+----------------+----------------+---------------+---------------+
-
-As you can see, the X300/X310 actually stores different IP addresses, which all address the device differently: Each combination of Ethernet port and interface type (i.e., Gigabit or Ten Gigabit) has its own IP address. As an example, when addressing the device through 1 Gigabit Ethernet on its first port (Port 0), the relevant IP address is the one stored in the EEPROM with key ``ip-addr0``, or 192.168.10.2 by default.
-
-See the `system configuration manual <./usrp_x3x0_config.html>`_ on details
-how to change your machine's IP address and MTU size to work well with the X300.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^
-Multiple devices per host
-^^^^^^^^^^^^^^^^^^^^^^^^^
-For maximum throughput, one Ethernet interface per USRP is recommended,
-although multiple devices may be connected via an Ethernet switch.
-In any case, each Ethernet interface should have its own subnet,
-and the corresponding USRP device should be assigned an address in that subnet.
-Example:
-
-**Configuration for USRP-X Series device 0:**
-
-* Ethernet interface IPv4 address: **192.168.10.1**
-* Ethernet interface subnet mask: **255.255.255.0**
-* USRP-X Series device IPv4 address: **192.168.10.2**
-
-**Configuration for USRP-X Series device 1:**
-
-* Ethernet interface IPv4 address: **192.168.110.1**
-* Ethernet interface subnet mask: **255.255.255.0**
-* USRP-X Series device IPv4 address: **192.168.110.2**
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Change the USRP's IP address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-You may need to change the USRP's IP address for several reasons:
-
-* to satisfy your particular network configuration
-* to use multiple USRP-X Series devices on the same host computer
-* to set a known IP address into USRP (in case you forgot)
-
-To change the USRP's IP address,
-you must know the current address of the USRP,
-and the network must be setup properly as described above.
-You must also know which IP address of the X300 you want to change, as identified by their address EEPROM key (e.g. ``ip-addr0``, see the table above).
-Run the following commands:
-
-**UNIX:**
-
-::
-
- cd <install-path>/lib/uhd/utils
- ./usrp_burn_mb_eeprom --args=<optional device args> --key=ip-addr0 --val=192.168.10.3
-
-**Windows:**
-
-::
-
- cd <install-path>\lib\uhd\utils
- usrp_burn_mb_eeprom.exe --args=<optional device args> --key=ip-addr0 --val=192.168.10.3
-
----------------------
-Addressing the Device
----------------------
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Single device configuration
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-In a single-device configuration,
-the USRP device must have a unique IPv4 address on the host computer.
-The USRP can be identified through its IPv4 address, resolvable hostname, NI-RIO resource name or by other means.
-See the application notes on `device identification <./identification.html>`_.
-Use this addressing scheme with the **multi_usrp** interface (not a typo!).
-
-Example device address string representation for a USRP-X Series device with IPv4 address **192.168.10.2**:
-
-::
-
- addr=192.168.10.2
-
-Example device address string representation for a USRP-X Series device with RIO resource name **RIO0** over PCI Express:
-
-::
-
- resource=RIO0
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Multiple device configuration
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-In a multi-device configuration,
-each USRP device must have a unique IPv4 address on the host computer.
-The device address parameter keys must be suffixed with the device index.
-Each parameter key should be of the format <key><index>.
-Use this addressing scheme with the **multi_usrp** interface.
-
-* The order in which devices are indexed corresponds to the indexing of the transmit and receive channels.
-* The key indexing provides the same granularity of device identification as in the single device case.
-
-Example device address string representation for 2 USRPs with IPv4 addresses **192.168.10.2** and **192.168.20.2**:
-
-::
-
- addr0=192.168.10.2, addr1=192.168.20.2
-
-
-----------------------
-Communication Problems
-----------------------
-When setting up a development machine for the first time,
-you may have various difficulties communicating with the USRP device.
-The following tips are designed to help narrow down and diagnose the problem.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-RuntimeError: no control response
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-This is a common error that occurs when you have set the subnet of your network
-interface to a different subnet than the network interface of the USRP device. For
-example, if your network interface is set to **192.168.20.1**, and the USRP device is
-**192.168.10.2** (note the difference in the third numbers of the IP addresses), you
-will likely see a 'no control response' error message.
-
-Fixing this is simple - just set the your host PC's IP address to the same
-subnet as that of your USRP device. Instructions for setting your IP address are in the
-previous section of this documentation.
-
-^^^^^^^^^^^^^^^
-Firewall issues
-^^^^^^^^^^^^^^^
-When the IP address is not specified,
-the device discovery broadcasts UDP packets from each Ethernet interface.
-Many firewalls will block the replies to these broadcast packets.
-If disabling your system's firewall
-or specifying the IP address yields a discovered device,
-then your firewall may be blocking replies to UDP broadcast packets.
-If this is the case, we recommend that you disable the firewall
-or create a rule to allow all incoming packets with UDP source port **49152**.
-
-^^^^^^^^^^^^^^^
-Ping the device
-^^^^^^^^^^^^^^^
-The USRP device will reply to ICMP echo requests ("ping").
-A successful ping response means that the device has booted properly
-and that it is using the expected IP address.
-
-::
-
- ping 192.168.10.2
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-USRP device not enumerated (Linux)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-UHD requires the RIO device manager service to be running in order to
-communicate with an X-Series USRP over PCIe. This service is installed as
-a part of the USRP RIO (or NI-USRP) installer. On Linux, the service is not
-started at system boot time, and is left to the user to control. To start it,
-run the following command:
-
-::
-
- sudo niusrprio_pcie start
-
-If the device still does not enumerate after starting the device manager, make sure that the host computer
-has successfully detected it. You can do so by running the following command:
-
-::
-
- lspci -k -d 1093:c4c4
-
-A device similar to the following should be detected:
-
-::
-
- $ lspci -k -d 1093:c4c4
- 04:00.0 Signal processing controller: National Instruments ...
- Subsystem: National Instruments Device 76ca
- Kernel driver in use: niusrpriok_shipped
-
-* A USRP X300 should appear with 'Subsystem: National Instruments Device 7736'
-* A USRP X310 should appear with 'Subsystem: National Instruments Device 76ca'
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-USRP device not enumerated (Windows)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-UHD requires the RIO device manager service to be running in order to
-communicate with an X-Series USRP over PCIe.
-This service is installed as a part of the USRP RIO (or NI-USRP) installer. On Windows, it can be found in
-the **Services** section in the Control Panel and it is started at system boot time. To ensure that the
-service is indeed started, navigate to the Services tag in the Windows Task Manager and ensure that the
-status of **niusrpriorpc** is "Running".
-
-If the device still does not enumerate after starting the device manager, make sure that the host computer
-has successfully detected it. You can do so by checking if your device shows up in the Windows Device Manager.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Monitor the host network traffic
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Use Wireshark to monitor packets sent to and received from the device.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Observe Ethernet port LEDs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-When there is network traffic arriving at the Ethernet port, LEDs will light up.
-You can use this to make sure the network connection is correctly set up, e.g.
-by pinging the USRP and making sure the LEDs start to blink.

+
+\tableofcontents
+
+\section x3x0cfg_hostpc Configuring your Host PC
+
+The USRP X3x0 is capable of delivering very fast sample rates to the
+host PC, and even high-powered desktops can have trouble keeping up at
+the higher rates. You can improve the performance of your host by
+configuring a number of settings that affect the performance of your
+computer.
+
+These are:
+
+- Kernel Version
+- Network Configuration
+- Power Management Configuration
+- Real-Time & Priority Scheduling
+- Building with ORC & Volk
+
+These items are covered in more detail, below.
+
+\subsection x3x0cfg_hostpc_kernel Kernel Version
+
+Performance issues may be encountered with Linux kernels earlier than
+3.11. Ettus Research strongly recommends using kernel version 3.11 or
+higher for high sample rates.
+
+\subsection x3x0cfg_hostpc_netcfg Network Configuration
+
+When using Ethernet interfaces to communicate with the device, it is
+necessary to configure a number of facets regarding your network
+connection.
+
+\subsubsection x3x0cfg_hostpc_netcfg_nwmgr Configuring NetworkManager
+
+Fedora and Ubuntu both use NetworkManager to manage network connections.
+Unfortunately, NetworkManager often tries to take control of a
+connection and will disconnect the interface.
+
+You should open your NetworkManager configuration and tell it to ignore
+the network interface you are using. **This is not the same as simply
+setting a static IP address.** You *must* tell NetworkManager to ignore
+the interface.
+
+\subsubsection x3x0cfg_hostpc_netcfg_ip Configuring the host's IP address
+
+On a Linux system, you can add a static IP address very easily by using the 'ip' command:
+
+ sudo ip addr add 192.168.10.1/24 dev <interface>
+
+Note that `<interface>` is usually something like `eth0`. You can discover the
+names of the network interfaces in your computer by running:
+
+ ip addr show
+
+\subsubsection x3x0cfg_hostpc_netcfg_sockbuff Configuring the Socket Buffers
+
+It is necessary to increase the maximum size of the socket buffers to
+avoid potential overflows and underruns at high sample rates. Add the
+following entries into /etc/sysctl.conf (root privileges required):
+
+ net.core.rmem_max=33554432
+ net.core.wmem_max=33554432
+
+Either restart the system or issue the following commands:
+
+ sudo sysctl -w net.core.rmem_max=33554432
+ sudo sysctl -w net.core.wmem_max=33554432
+
+\subsubsection x3x0cfg_hostpc_netcfg_mtu Configuring the MTU
+
+In order to achieve maximum performance, we recommend setting the MTU
+size to 9000 for 10 GigE and 1500 for 1 GigE. It is possible to use
+smaller MTUs, but this can affect performance. With some NICs, setting
+the MTU too high can also cause issues. To set the MTU to 9000, you can
+use the following command:
+
+ sudo ifconfig <interface> mtu 9000 # For 10 GigE
+ sudo ifconfig <interface> mtu 1500 # For 1 GigE
+
+Using these MTUs will set the frame sizes for UHD communication to 8000
+and 1472, respectively.
+
+In some cases, specifying the frame size manually by adding the argument
+`<send/recv>_frame_size=1472` can solve issues. Note that a frame
+size of 1472 will limit the available sampling rate, although this is
+not a problem on 1 GigE.
+
+\subsubsection x3x0cfg_hostpc_netcfg_firewall Configuring the Firewall
+
+Many Linux distributions come installed with a Firewall, by default. The
+Firewall will often interfere with your ability to communicate with your
+USRP. You should configure your firewall to "trust" the interface you
+are using. Setting this properly depends on your OS and firewall
+configuration method.
+
+When using UHD software, if an IP address for the USRP-X Series device is not specified,
+the software will use UDP broadcast packets to locate the USRP-X Series device.
+On some systems, the firewall will block UDP broadcast packets.
+It is recommended that you change or disable your firewall settings.
+
+\subsubsection x3x0cfg_hostpc_netcfg_if Interface Configuration File (Fedora)
+
+On Fedora systems, you can configure the network interface mostly from
+one place (with the exception of the socket buffers). Each interface on
+your system should have a file in:
+
+ /etc/sysconfig/network-scripts/
+
+As an example, if your 1GigE interface is "em1", your "ifcfg-em1"
+configuration file should look something like this, when configured for
+use with a USRP X3xx:
+
+ TYPE="Ethernet"
+ BOOTPROTO="none"
+ IPADDR0="192.168.10.1"
+ DEFROUTE="yes"
+ IPV4_FAILURE_FATAL="no"
+ IPV6INIT="no"
+ IPV6_FAILURE_FATAL="no"
+ NAME="em1"
+ UUID="<specific to your device>"
+ ONBOOT="no"
+ HWADDR"<specific to your device>"
+ PEERDNS="yes"
+ PEERROUTES="yes"
+ ZONE="trusted"
+ MTU="9000"
+ NM_MANAGED="no"
+
+The above file was generated and modified on a Fedora 20 system.
+
+\subsection x3x0cfg_hostpc_pwr Power Management
+
+Power management on the host system attempts to save power by reducing
+clock frequencies or even powering off devices while not in use. This
+can lead to significant performance issues when trying to operate at
+high sample rates. Ettus Research strongly recommends disabling all
+power management.
+
+\subsubsection x3x0cfg_hostpc_pwr_cpugov Setting the CPU Governors
+
+In Linux, the CPU governors dictate the frequency at which the CPU
+operates and attempt to reduce the CPU frequencies at certain times to
+save power. When running at high sample rates, reduction of CPU
+frequencies can cause significant performance issues. To prevent those
+issues, set the governor to "performance".
+
+**Ubuntu:** 1. Install cpufrequtils:
+
+ sudo apt-get install cpufrequtils
+
+2. Edit `/etc/init.d/cpufrequtils` and set `GOVERNOR="performance"` on the
+ appropriate line (run as root):
+
+ sed s/^GOVERNOR=.*$/GOVERNOR=\"performance\"/g /etc/init.d/cpufrequtils > /etc/init.d/cpufrequtils
+
+3. Restart cpufrequtils:
+
+ sudo /etc/init.d/cpufrequtils restart
+
+\b Fedora:
+
+ sudo cpupower frequency-set -g performance
+
+\subsection x3x0cfg_hostpc_rtprio Real-Time & Priority Scheduling
+
+Enabling real-time and priority scheduling can improve the total
+processing throughput of your application. Priority scheduling should be
+enabled for UHD, and real-time scheduling can be enabled by your
+application.
+
+\subsubsection x3x0cfg_hostpc_rtprio_thread Thread Priority Scheduling with UHD
+
+For information regarding how to enable priority scheduling for UHD on
+your system, please see \ref page_general.
+
+\subsubsection x3x0cfg_hostpc_rtprio_app Real-Time Scheduling in your Application
+
+Please note that turning on real-time scheduling in your application
+**may lock up your computer** if the processor cannot keep up with the
+application. You should generally avoid using real-time scheduling
+unless you need to.
+
+Real-time scheduling is enabled via different methods depending on your
+application and operating system. In GNU Radio Companion, it can be
+turned on in each individual flowgraph.
+
+\subsection x3x0cfg_hostpc_volk Building with ORC & Volk
+
+Especially when running high-performance applications, processing
+performance can be dramatically improved by SIMD instructions. UHD uses
+ORC to provide SIMD capability, and GNU Radio includes a SIMD library
+called "Volk". These should both be used to guarantee optimum
+performance.
+
+\subsubsection x3x0cfg_hostpc_volk_orc Compiling UHD with ORC
+
+ORC, the <a href="http://code.entropywave.com/orc/">Oil Runtime Compiler</a>,
+is a third-party compiler that UHD uses to create efficient SIMD code for
+your particular computer. ORC is generally easily installed from your
+OS's package manager.
+
+On Fedora:
+
+ $ sudo yum update; sudo yum install orc-compiler orc-devel
+
+On Ubuntu:
+
+ $ sudo apt-get update; sudo apt-get install liborc-<version> liborc-<version>-dev
+
+After installing ORC, when building UHD from source, you should see
+"ORC" as one of the configured UHD components.

+\section x3x0cfg_hosthw Host PC Hardware Selection
+
+\subsection x3x0cfg_hosthw_mb Motherboard
+
+Testing has shown that some motherboards do not provide enough PCIe bus
+bandwidth to support higher sample rates. Motherboards with PCIe 3.0 are
+required and the PCIe architecture of the motherboard should be
+carefully considered. Slots with dedicated PCIe lanes should be used for
+PCIe or 10GbE cards that will be connected to the X3x0 device.
+
+\subsection x3x0cfg_hosthw_10gige 10GbE NIC
+
+Intel or Myricom 10GbE NICs are recommended. Mellanox, SolarFlare, and
+Chelsio 10GbE NICs are not currently recommended. The Ethernet card
+should be plugged into the slot that has the most direct connection with
+the CPU (PCIe lanes are not shared with another slot). Refer to the
+motherboard manual for more information on PCIe architecture.
+
+\section x3x0cfg_hosthw_troubleshooting Troubleshooting Performance Issues
+
+The output on the host console provides indicators of performance issues
+in the form of single upper-case letters. The following table lists the
+letters, their meanings, and possible causes:
+
+ Indicator |Meaning | Possible Causes
+ -----------|----------------------|---------------------------------------------------------------------------------
+ O |Overflow on RX |- Data is not being consumed by user's application fast enough.<br>- CPU governor or other power management not configured correctly.
+ D |Dropped packet on RX |- Network hardware failure. (Check host NIC, cable, switch, etc...)<br>- PCIe bus on host cannot sustain throughput. (Check ethtool -S \<interface\>).<br>- CPU governor or other power management not configured correctly.<br>- Frame size might not work with the current NIC's MTU.
+ U |Underflow on TX |- Samples are not being produced by user's application fast enough.<br>- CPU governor or other power management not configured correctly.
+ L |Late packet (usually on MIMO TX)|- Samples are not being produced by user's application fast enough.<br>- CPU governor or other power management not configured correctly.<br>- Incorrect/invalid time_spec provided.
+ S |Sequence error on TX |- Network hardware failure. (Check host NIC, cable, switch, etc...)<br>- Frame size might not work with the current NIC's MTU.
+
+\subsection x3x0cfg_hosthw_troubleshooting_eth Troubleshooting Ethernet Issues
+
+1. First, check `ifconfig <interface>` to see if there are any errors
+ reported on the interface. If there are errors, it is most likely a
+ network hardware problem.
+2. Next, check the output of `ethtool -S <interface>`. The output is
+ driver-specific, but may give important clues as to what may be
+ happening. For example, a high value on rx_missed_errors for an
+ Intel NIC indicates that the bus (i.e. PCIe) is not keeping up.
+3. Finally, Wireshark can be used to validate the traffic between the
+ host and device and make sure there is no unwanted traffic on the
+ interface.

-1. First, check 'ifconfig <interface>' to see if there are any errors reported
- on the interface. If there are errors, it is most likely a network hardware
- problem.
-2. Next, check the output of 'ethtool -S <interface>'. The output is
- driver-specific, but may give important clues as to what may be happening.
- For example, a high value on rx_missed_errors for an Intel NIC indicates
- that the bus (i.e. PCIe) is not keeping up.
-3. Finally, Wireshark can be used to validate the traffic between the host and
- device and make sure there is no unwanted traffic on the interface.
