For wider dynamic range digital gain adjustment, the FPGA PL can be used.
Similarly to the QMC Gain method, the latency through the VGA, RF-ADC and datapath should be used to delay the application of the gain change in
the PL. After the PL gain change, the thresholds can be cleared by a call to the XRFdc_ThresholdStickyClear API function, or by issuing an
adcXY_pl_event after the event source has been set by a call to the XRFdc_SetQMCSettings API function.
