AGC and Dynamic Range of ADC

I have USRPN210 with WBX and RFX2400. Is there any AGC chip on N210
motherboard or WBX, RFX2400 before ADC to utilize the dynamic range of
ADC
? if yes, which one? If not, then won’t the varying input signal (for
example signal from moving object) to ADC affect the performance of ADC
?

Bob

Can somebody please guide me on this ?

Well that is 80 dB of dynamic range inside the Nyquist zone (at best and
let’s call it N). I can add a “bit” of increase in dynamic range by
downsampling (filter and decimation) and growing the accumulator size by
a
bit for each decimation by 4. This will increase dynamic range. I
don’t
believe this is happening to a large extent in the N210 unless it is
included in you 80 dB number which I believe is you just doing 14 bits
of
ADC is 80 dB.

The ADC on an N210 has over 80dB of dynamic range. If that isn’t
enough, then your application can adjust the RF gain to taste.

Only a subset of applications actually benefit from the usual hardware
AGC schemes, and such schemes are invariably application-specific, so
there’s
no automatic gain control. But your application can dynamically
make gain adjustments as it goes.
