AWR6843AOPEVM: Use mmWave studio setting 3Tx mode

Tool/software:

Hi Ti experts,

I used DCA1000 with mmWave studio to perform Beamforming experiments.
Can I create a 3 Tx simultaneous transmission mode through Contstream in mmWave studio and adjust the Power and Phase shifter?

    HI, Vincent:

    ContSteam is used for CW mode.  I would suggest you to use multiple ProfileCfg to program different phase shifter for each TX channel.  

    For example, in each profile, you can program the desired phase shifter for each TX. 

    ar1.ProfileConfig(0, 77, 100, 6, 60, 0, 0, 0, 0, 0, 0, 29.982, 0, 256, 10000, 0, 0, 30)

    ar1.ProfileConfig(1, 77, 100, 6, 60, 0, 0, 0, 0, 180, 0, 29.982, 0, 256, 10000, 0, 0, 30)

    ar1.ProfileConfig(2, 77, 100, 6, 60, 0, 0, 0, 0, 0, 180, 29.982, 0, 256, 10000, 0, 0, 30)

    ar1.ChirpConfig(0, 0, 0, 0, 0, 0, 0, 1, 1, 1)

    ar1.ChirpConfig(1, 1, 1, 0, 0, 0, 0, 1, 1, 1)

    ar1.ChirpConfig(2, 2, 2, 0, 0, 0, 0, 1, 1, 1)

    In this way,

    chirp0 is TX1 + TX2 + TX3

    chirp1 is TX1 - TX2 + TX3

    chirp2 is TX1 + TX2 - TX3

    Let me know if this makes sense to you.

    Best,
