[USRP-users] TwinRX Gain

Hello,

I am trying to understand the 'actual' gain in TwinRX.  Experimentally, I see that a 0 dBm input requires gain of +46 dB to give a full-scale (-1/1) output.  Interestingly, the two channels have about 3 dB of difference in gain (I would have expected a lot less).  Since the A/D expects about 0 dBm (based on the datasheet), it appears we only have 50 dB of actual gain available.  Is that correct?  What does the 95 dB of gain mean?

Thanks.
