IWR6843ISK: Adjust IWR6843ISK antenna transmi power

Intellectual 310 points
Part Number: IWR6843ISK

Tool/software:

I need a cfg command to adjust the transmit power.  What is the maximum?  I think maybe 12dBm.  Can it be adjusted to exact levels?  

Regards,

    Hello Larry,

    It will be TX Backoff power. By default it is at maximum transmission power. For 6843 the field is within profileCfg

    profileCfg 0 60.75 30.00 25.00 59.10 394758 0 36 1 96 2950.00 2 1 36
    The way this field works is by converting the decimal value to its hex counter part and using it to apply a backoff to each TX. 
    394758 = 0x060606 so it will add a 6dB TX backoff to all three TXs
    Best Regards,
    Pedrhom
