Hello
I've just successully installed gnuradio and connected my new USRP n210. I run uhd_fft.py to test my hardware and it all works well, I activity in the spectrum.
The thing is, whatever I set the center frequency, all I see is a carrier at that center frequence at -50dB and "noise" at other frequencies at -70dB. I have included 2 screenshots with center frequencies of 2.4G and 2.4001G, the situation is the same in both of them.
I thing there is something really wrong with this. Besides, I remember a few time when I ran uhd_fft.py file, I saw noise at -110dB and several carriers at different frequencies. But that carrier at center frequency was there too.
I appreciate any help
Thanks
