AWR1642: txPhaseShifter availability in 1843?

Part Number: AWR1642
Other Parts Discussed in Thread: AWR1843

Hi, 

I noticed that txPhaseShifter should be available for 1843 in profileCfg of SDK 3.1.1.2's sdk _ser_guide. I checked the source code but I could not find where txPhaseShifter is parsed. So I am wondering is this feature supported by the 3.1.1.2 SDK or it is still under developing? 

By the way, I can not choose 1843 as the part number so I choose 1642 instead.

Thanks.

    Tiancong,

    The txPhaseShifter is available to use with AWR1843 in SDK 3.1.1.2. You can find specific information about the phase shifter in the SDK documentation found at:
    C:/ti/mmwave_sdk_03_01_01_02/packages/ti/control/mmwavelink/docs/doxygen/html/structrl_profile_cfg__t.html

    You can search for "txPhaseShifter" in this file.

    For the Out-of-Box demo that is included in the SDK, the phase shifter set to 0 because only a value of 0 has been tested per the SDK User's Guide documentation. It would not be necessary to implement any additional parsing code since none of the chirps are phase shifted in the example code.

    Regards,
    Kyle

    Thank you for the link of documentation. So no additional parsing code means that it will not affect anything if the txPhaseShifter is set to other value ? If it does not affect anything now, will other value be supported in the future?

    Thanks.

    Tiancong,

    If you are looking to evaluate the TX Phase Shifter, you can use mmWave Studio and the firmware that is provided in the mmWave Studio installation folders.
