Thanks, Marcus, for your prompt and detailed response. If I understand you
correctly:
1. The best case noise figure of the RFX900 daughterboard is about 3-3.8 dB.
This occurs when the mixer amplifiers are set to their highest gain setting.
2. These gain settings can be fixed via software (via UHD)

Hi,
I have a few questions about the (analog) AGC on the AD8347 mixer chip on
the Flex900 daughterboard.
1. Given a signal received with some known power, is it possible to read the
programmed AGC gains (and thereby find the mixer's noise figure)?
2. Is it possible to lock these gain settings? If
