I’ve recenty got two USRP N200 with SBX daughter boards. I have managed
transmit simple sine signal with one USRP but I have problems receiving
this signal. I dont see anything but noise in spectrum. I have measured
signal that I am transmiting with spectrum analyzer and I see a spike in
spectrum, so the transmiter must be working.
I am using UHD source and sink blocks as a “top layer” for USRP devices,
and WX GUI FFT block for displaying spectrum. Sine frequency is 1kHz and
am samping with 200kHz. I have set the center frequency on 500MHz. I
tried both antenna ports on receiving device.
Is there some setting that I am missing?
