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
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.
