AWR1642BOOST: How do we change TX2 of AWR1642BOOST output power in mmWave Demo mode

Hello Abe-san,

The Tx power can be changed changing the  profile configuration.

You can look at the "AWR1xxx Radar Interface Control Document.pdf" available in the MMWAVE-DFP and refer section "Sub block 0x0100 – AWR_PROFILE_CONF_SET_SB"  for the profile configuration message. The "PF_TX_OUTPUT_POWER_BACKOFF" needs to be programmed to change the TX power.

In the context of the mmWave demo , to change TX2 and TX3 you can do the below modification

Default with no Tx power reduction.

profileCfg 0 77 3 3 56 0 0  8 1 256 5000 0 0 30

New profile configuration configuring the TX1, TX2 to reduce the power by 3dB (TX backoff power : 0x0303 = 771)

profileCfg 0 77 3 3 56 771 0  8 1 256 5000 0 0 30

Thanks,

Raghu
