MMWCAS-RF-EVM: Missing procedure to generate "phaseMismatchCalibration.mat" for TxBF Calibration

Hi,

We use "cascade_TxBF_dataCapture.m" script to configure/capture data in TxBF mode. This code basically uses two .mat file "phaseShifterCalibration.mat & phaseMismatchCalibration.mat". We know the procedure to generate "phaseShifterCalibration.mat" but are stuck to generate "phaseMismatchCalibration.mat". Meanwhile, the TI document "mmwave_studio_cascade_user_guide.pdf" describes to use "calibrateResults_high.mat" in place of "phaseMismatchCalibration.mat" for data collection in TxBF mode. It is noted that "calibrateResults_high.mat" is generated using the data obtained in MIMO mode. Now, the question is why the data contents in the "calibrateResults_high.mat" is different that of "phaseMismatchCalibration.mat" file? or Is there any procedure to generate "phaseMismatchCalibration.mat" file for TxBF mode? Please clarify.

Regards,

Sureshbabu
