We are trying to perform phase calibration on FMCOMMS5 by using IIO Scope. I attached the screenshot of IIO Scope cal settings.
We repeat phase cal two or three times successively after the previous one completed successfully. However every phase cal results (RX1/RX2, RX3/RX4 Phase Rotation) quite different from each other. I expect consistency in cal results (phase differences) since nothing(temperature or other settings) changes between two consecutive calibrations.
Or are we missing something? I also attached two consecutive cal phase results.
1st cal phase rotation:
RX1/RX2: 1.22 ; RX3/RX4: 132.94
2nd cal phase rotation:
RX1/RX2: 104.06 ; RX3/RX4: 145.72
