Hi,I transmitted 0.3 + 0.3i signals on the 900e6 frequency(i.e. sudo ./tx_waveforms --rate 1e6 --freq 900e6 --ref "external" --gain 85)and then I received the signal(i.e. sudo ./rx_samples_to_file --type "float" --rate 1e6 --freq 900e6 --gain 40 --nsamps 10000)and then I extracted the real and imaginary parts using MATLAB and plotted it.I expected a constant line(i.e. 0.3*gain on real, 0.3*gain on imag) on both real and imaginary figures since I transmitted a constant real and imaginary signal, but the figures were beyond my expectation. I attached the figures.Q1. Is it normal behavior?Q2. If it does, what's the source of this fluctuation?Here are my experimental setup.-Experimental setup:USRP B200 TX/RX <---> 30dB attenuator <----cable----> USRP B200 RX2Ref port on both USRP b200 are connected to the Octoclock-G. The octoclock-G use external antenna.the UHD version is "UHD_3.11.0.1-16-g34fc6362"Regards,Hojoon
