AWR2944EVM: txPhaseShifter

Other Parts Discussed in Thread: AWR2944

Dear sir,

I want to test txPhaseShifter in AWR2944EVM.

First I load "sbl_qspi.release.tiimage" and "awr2944_mmw_demoDDM.appimage" to EVM.

second I open "profile_advanced_subframe_DDMA_awr2944.cfg" in mmWave_Demo_Visualizer 4.4.0.

And I blocked a portion of the transmission and reception, only revealing the RX0 TX0 TX1.

I chang txPhaseShifter of profileCfg, but the echo is not change.

“Bits 0 and 1 are reserved and should be set to zero while the bits 2 to 7 represent the TX0 phase shift value.”

If txPhaseShifter can be used in EVM?

    Hi,

    As mentioned in the SDK user guide we have not tested any other value for Tx phase shifter. Only zero has been tested with the OOB demo. In general, you can use this parameter.

    Currently what are your conducted experiments and observed results. Can you provide more information on this.

    Thanks,

    Pradipta.
