How can I measure the RSSI with SBX board

Hi all,

It is seen that the RSSI can be obtained by the read_aux_adc.
But I am not sure if SBX board supports it or not. And how to specify
the
parameters:

int which_side, int which_adc

Any hints for this question?

Thanks!

Hardware RSSI is only available on some daughtercards, and is usually
not accurate with respect to the final bandwidth of interest.

Generally if you want to measure received power over your final
bandwidth of interest, just insert a complex-to-mag**2 in the stream,
and average that and decimate, and you’ll have a good received power
estimate.
