CCS/AWR1843BOOST: Questions about AWR1843BOOST TX_OUT-PUT_POWER_BACKOFF option Settings

Part Number: AWR1843BOOST

1.The parameter description given in the user manual is shown in the figure above。

2.I set this parameter to 394758u（0x060606）, and then I tested it and found that it had no effect on the maximum distance. Okay?Or is there something wrong with the parameters that I set?

Hi ,
Using the backoff code will reduce the TX output power of the transmitter.

How did you verify your that there is no effect on the maximum distance?

Hi,
I found it through the actual scene test.
If the transmission power is reduced and other parameters remain unchanged, the maximum detection distance should be reduced.
But I found that the maximum detection distance did not change.

Hi Cheng,

Do you mean you are able to detect objects as far as 150m or more with reduced TX power?

I mean, if the power is reduced, the detection distance will be smaller, but setting parameters in the program cannot achieve this scenario.

You can further reduce the power and check that the range will decrease. Do not see any reason why the transmit power will not decrease.
