I am transmitting a continuous wave and using one USRP B210 with the kitchen_sink tool in order to save the received samples from two RX channels (v.3.15.0)
When I look into the received signal on both channels, it seems that the Gain factor is only being applied to one of the channels as shown below.
This is the command that I am sending when executing kitchen_sink:
./kitchen_sink --rx-freq=868000000 --rx-gain=76 --rate=1e6 --rx-channels=0,1 --rx-ant=TX/RX --rx-file=data/_%1%_usrp.dat --clock=external --time=external --rx-start-delay=3 --rx-freq-delay=0.5
My UHD version is 3.15.0
What could be causing the difference in the signal between the two channels?
