AWR1843BOOST: Some questions about TX config

Gmsy Bryant

Part Number: AWR1843BOOST

Hello,TI's expert

    When i develop base on AWR1843Boost,and i meet a problem.We have two mode,they are short range mode and long range mode.

    And i config the profile/chirp/advanced frame.The profile is same,short range mode chirp is 0 to 255,open with tx1,long range mode is 256 to 511,open with tx2 && tx3.

    When I run these two modes separately,the RDM is correct.See as follow:

    However run together,first subframe1(short ) then subframe2(long ),the RDM data will be error,the doppler dim will expand .See as follow:

   TX1 turned on when I configured long range mode as well as short range mode,the error will disappear.So in long range mode I can't turn on any other antenna except tx1.I also verified this in MMWave Studio.Where is the problem?Is it the limitations of the chip itself or the interference between the transmitting antennas?

    Hi,

    Thank you for performing these tests.

    I think it is easier to debug this issue with mmWave Studio because this will rule out the target sw.

    Can you share the mmWave Studio Config?

    thank you

    Bryant,

    Would you able able to share your mmWave Studio configuration so that we can review it and identify if there are issues, if any, with the configuration?

    Please make sure all of the TX channels are enabled in the StaticConfig tab and are available to use if your profile/chirp configurations.

    Regards,
