AWR1843: Phase shifter per chirp calibration

Hamid Afrasiabi Vayghan

Part Number: AWR1843

Is phase-shifter calibration data in AWR1843 pre-stored by TI? I face phase inaccuracy for phase shifter,whenever program embedded application for AWR1843. But when I use mmwave Studio and apply the same configuration and capture time domain samples, I see the phase shifter are working well.

I tried in my SW: rlRfPhShiftCalibDataStore() to read phaseshifter calibration data from device. But the data fetched all '0'

I need this data to be used by rlRfPhShiftCalibDataRestore().

Any help? Any demo project?

Thank you

Hi,

Thanks Cesar. I look forward it. Just adding more info to my post, I use per chirp phase shifter and enable it in top by means of

phaseShiftPerChirpEnable.miscCtl = 1; // Enable per chirp Phase shift
retVal = rlRfSetMiscConfig(RL_DEVICE_MAP_INTERNAL_BSS, &phaseShiftPerChirpEnable);

This issue has been resolved offline.

In the next months we will release an example of configuration that shows how to program the AWR1843 phase shifters

Closing the thread now

Thank you
