| * b200: Updated minimum clock rate to match DCM changesMartin Braun2015-10-143-4/+8
| | | | | | | | | | | | Lowest master clock rate is now 220 kHz. At low clock rates, the convergence time for the DC offset and quadrature calibration times is much larger, though.

| | | | | | | | | | | | - gpio_atr_3000 will not blindly use the mask when writing the ATR and GPIO OUT values. The mask will be ANDed with the value in the ATR Disable register

* ad9361: Delay Tx Quad Cal from initialization to streamer startTom Tsou2015-08-131-2/+8
| | | | | | | | | | | | | | | | | | | Patch addresses issue: #742 "tx_waveforms seems to produce unexpectedly large image" Tx Quad Cal performance is temporally dependent with better results when run after the AD9361 is configured for transmission than at initialization. This gets is roughly 5-10 dB of additional quadrature image suppression. Even better performance can be reached when Tx Quad Cal is run after streaming and the AD9361 is actively transmitting. Calibration in this state, however, requires user intervention by retuning the transmit chain by > 100 MHz. Total IQ suppression should be in the range of 40-50+ dBFS dependent on operating frequency. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
* ad9361: Use separate Tx and RX frequency calibration intervalsTom Tsou2015-08-132-19/+39
| | | | | | | | | | | | | | | | | | Patch addresses issue: #872 "B200: Tx and Rx calibration share same frequency state" ADI specifies recalibration for certain paths when the LO shifts by more than 100 MHz. Tx and Rx maintain independent LO frequencies so use separate values for determining whether to perform re-calibration at tuning intervals. Also, maintain last calibration frequencies from initialization and clock rate changes. Doing so prevents a re-calibration if the first requested Tx or Rx frequency is close to the default values of 850 and 800 MHz respectively. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
* ad9361: Reconfigure RF and baseband DC offset correctionTom Tsou2015-08-132-37/+39
| | | | | | | | | | | | | | | | | | | | | | | | Addressed and related issues: #186 "B200: Catalina RX signal distortion" #821 "Incorrect behavior with auto DC Offset correction turnned off" #820 "Rx DC Offset Correction Convergence on B2xx Dependent on Master Clock Rate" #755 "Demodulate IQ signal amplitude oscillation on B210 at 200 MHz carrier" Due to recent change "ad9361: Invert phase on Rx LNA bypass path", we now have uniform phase alignment across the entire gain range. This drastically improves performance of RF DC tracking - not to be confused with the - active and input dependent - baseband (BB) DC tracking loop. RF DC tracking is not affected by input signals and updates during gain changes. The updated configuration provides improved DC suppression for operation whether BB tracking loop is enabled or disabled. New behavior differs from the previous case where disabling BB tracking would clear all - static and active - calibration tables. Now, static correction tables are not wiped when BB tracking is turned off. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
* ad9361: Enable single shot Rx Quad CalTom Tsou2015-08-132-31/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | Patch provides an alternative resolution to issue #807 "B210: severe distortion on In-phase data for some gain settings" Rx quadrature tracking, an active input-sensitive loop, causes problems on a handful of receive signals. Problematic signals include pulsed GMSK and near-DC tones among others. As an alternative, improve operation when active tracking is disabled. Run single shot quadrature calibration at the following events to provide calibrated image suppression. The corrections without active tracking are not input dependent. Rx quadrature single shot calibration points: 1. AD9361 initialization 2. Clock rate change 3. Tuning differences greater then 100 MHz when tracking is disabled Note that if tracking is enabled (default case), this patch has no effect during streaming. Only the non-default (user set) case is affected. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
