Hi champion,
I want to check the RF Init phase shifter cali result in mmwave studio. I did the test referencing 3.2.2 in spracv2 'cascade_coherency_and_phase_shifter_calibration'.
- call RF_init with Tx phase shifter cali enabled
- Save Tx phase shifter calib data in file .
The file is attached.

I reformatted it as the description in spracv2 A.5 ,and got below Tx phase shifter calibration value per Tx ants. Is this value valid? It seems the phase shifter cali value for phase idx 0 is about 90 degree. How to understand it?
