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. + +\section Hardware Reference + +\subsection LED Indicators + +Below is a table of the LED indicators and their meanings: + +<table> + <tr> + <th>Component ID</th><th>Description</th><th>Details</th> + </tr> + <tr> + <td>LED600</td> <td>Power Indicator</td> <td>off = no power applied<br> + red = power applied (external or USB)</td> + </tr> + <tr> + <td>LED800</td> <td>Channel 2 RX2 Activity</td> <td>off = no power applied<br> + green = receiving</td> + </tr> + <tr> + <td>LED801</td> <td>Channel 2 TX/RX Activity</td> <td>off = no activity<br> + green = receiving<br> + red = transmitting<br> + orange = switching between transmitting and receiving</td> + </tr> + <tr> + <td>LED802</td> <td>Channel 1 TX/RX Activity</td> <td>off = no activity + green = receiving<br> + red = transmitting<br> + orange = switching between transmitting and receiving</td> + </tr> + <tr> + <td>LED803</td> <td>Channel 1 RX2 Activity</td> <td>off = no power applied<br> + green = receiving</td> + </tr> + <tr> + <td>LED100</td> <td>GPS lock indicator</td> <td>off = no lock<br> + green = lock</td> + </tr> +</table> + +TX LED indicators are on when transimitting data and off when no samples are +available to transmit. RX LED indicators are on when sending samples to the +host and off when unable to do so. This means that TX/RX activity LED +indicators will blink off in a temporary transmit underflow or receive overflow +condition, indicating that the host is not sending or receiving samples fast +enough.
