[Discuss-gnuradio] Fluctuating gain in flex1800 ?

[Per Zetterberg]

Dear All,

I am sampling a CW (1766.6MHz) using an flexrf1800. The amplitude seems to
fluctuate 0.3dB (peak-to-peak). It don't think it is due to measurement
noise because the SNR is high. Is this behaviour normal or am I likely doing
something wrong ? 

Could it be the signal from the D/A converter (which controlling the gain of
the RX chain) that is noisy ?
