I'm trying to understand how ADC\DAC phase calibration is performed for I\Q channels.
ADI IIO scope software has calibration tab that provide DAC\ADC Gain, Offset, Phase calibration parameters. Separate for I and Q channels.
There is a question about Phase calibration parameter.
DAC has a special registers for phase calibration.
There is no any registers for phase correction on ADC. How the ADC Phase correction for I and Q channels are working?
