TIDEP-01012: What is the phaseShifterActual in cascade beamforming configuration?

Hi Frank, 

That table was the result of a per TX phase-shifter calibration that was performed on a single Cascade RF EVM. It is representative of the kind of skew designers will encounter and represents the TX phase shifter + AWRx die/package + PCB TX phase skew. But to get the most accurate results, this data should ideally be taken on the specific PCB system under test. So ideally, you should run this on the specific Cascade RF EVM you are working with or your own AWR+PCB system. 

Currently we do not have an example of the full phase-shifter calibration process used to gather that data. But we are considering releasing an example process and script set in our Matlab post-processing library. 

Thank you,

-Randy
