Yes, signals below -20dBm

I think that i am a little bit confused with calibration. Is there any
way to determine the gain of the circuitry in front of the ADC? Is it
correct enough to say that power level at the input of PGA in front of
ADC is
just ((sampled_value*Vp-p)/2^12 ^ 2 ) / Rinputpga?
The total gain in fron
Thank you Marcus for super fast answer. Well, for the begining I would like
to skip temperature calibration, only power level calibration regarding
frequency. I have following doubts:
1. To which frequency should be tuned USRP if for example generator
generates 400 MHz. Should it be almost the same
Indeed, the only way to do this is to use a signal generator with known power levels, and precision attenuators. You'll have to repeat the process over the full tuning range of the device(s) in question, since effective gain will change a little with tuned frequency--that's just a natural property
Hi all guys (yet again),
I have a question about calibrating received power level of my USRP,
equipped with wbx, lftx and lfrx.
I am not sure whether it is apropriate to discuss that here.
Basically I would like to be able to determine absolute power level I am
receiving. I suppose that basic proce
