* | ad9361: Prevent positive loop gain on Rx quadrature trackingTom Tsou2015-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes a portion of #807 "B210: severe distortion on In-phase data for some gain settings" ADI recommends that the "Prevent Pos Loop Gain" setting be enabled to prevent the Rx quadrature tracking loop from becoming unstable at low power levels. ADI Linux kernel driver also reflects this setting. We do not follow the ADI recommendation. Adjust accordingly. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
* | ad9361: Invert phase on Rx LNA bypass pathTom Tsou2015-07-131-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch resolves issue #823 "B200: Receive RF DC calibration makes calibration worse below 34 dB" According to ADI reference documents, enabling any of the 3 LNA's in the receive path causes a 180 degree phase shift. Correspondingly, we invert the LNA bypass path (gain indices below 34 dB) to match. Testing, however, reveals that one of these statements or the polarity inversion setting itself is false. Disabling the switch results in expected behavior and proper phase alignment. Overall effect is up to 60 dB of DC offset suppression ahead of the Rx analog LPF. This reduces the problematic dependency on active baseband tracking and may resolves multiple tracking stability issues. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>

| | * b200: Modify initialization sequence to avoid warningsMartin Braun2015-06-292-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will set the actual default rate to an integer factor of whatever the tick rate is, but leave the property tree value at zero. This avoids warnings if the chosen tick rate is not a multiple of the previous default rate, but also returns a zero value for the rate when it has not been initialized, allowing the user to probe if the value has not yet been set.

| | | | | | | | | | | | | | | | | | | | | | | | - Self-calibration routine steps through various values of LMK delay to detect metastability in the SSCLK -> radio_clk crossing and computes an ideal delay for the ADC clock. - Self calibration is triggered at startup if the self_cal_adc_delay device arg is specified
