Could you give some details of AGCBACKOFFGAIN?

Hi Nordic,

It mentions that "Gain will be lowered by the specified number of gain steps at the start of CTE. Note: First LNAGAIN gain drops, then MIXGAIN, then AAFGAIN" in nRF52833's PS v1.3, however, there is no explaination about the step, LNAGAIN, MIXGAIN or AAFGAIN. 

Besides, what are the ordinary value/range of the I/Q samples (based on some AGCBACKOFFGAIN value maybe, e.g., when AGCBACKOFFGAIN = 0)? I usually get 100~200. Is it too small for the 12bit ADC? Is it possible that the samples value would impact other samples nearby? For example, if a sample's value is very large, the next sample would be larger than it should be?

Thanks.
