I run Zedboard + FMCOMMS2 with gnuradio for cyclic-sine.grc file. I can observe the output from QT GUI Sink, then I add QT GUI Range to vary frequency source signal so that I can verify the response on Sink. But unfortunately the output didn't reflect on frequency that I changed- No change on output on QT GUI Sink.
For example I expect that if I sweep the frequency, than I can see movement of spectrum to other side, but the example fail to response.Time domain display also not show sine waveform..
There something I missing here.. Thank you
