Subject: | [Discuss-gnuradio] Re: problem with USRP/FFT sink in GRC |
Date: | Mon, 30 Apr 2007 18:15:36 -0400 |
Hi,
I am running a simple graph in GRC-0.65 with complex USRP as source
(with TVRX at the B side) and a complex FFT as a sink.
What I see is not expected: I see the FFT of a real signal
(symmetric around 0).
When I run the python example usrp_fft.py I get
the expected result.
./usrp_fft.py -RB -f 93.1e6 -d 16
I attach the grc graph for anyone who wants to take a look at it
and give me some hint as to what I might be doing wrong.
Thanks
Achilleas
