Dear Aadil,
- First upgrade to latest gnuradio release.
- Put the USRP behind.
- Start generating the sinewave by software using gr.sig_source
- Do the mathematics or FFT or whatever you want on this simulated
signal. - If everything is ok, switch back to USRP, if not, then you have a
problem in using the gnuradio, and you should learn more.
Regards,
Firas

Subject: Re: [Discuss-gnuradio] Signal reconstruction
Also, it’s not clear to me what you’re actually trying to do.
I’d like to capture FM signals and perform ambiguity measurements on
them.
at the moment, i am failing to capture data correctly.
If you want to plot data in real time, please use either the
usrp_fft.py or usrp_oscope.py applications. You can capture data
to disk using the usrp_rx_cfile.py example.
I suggest you start with these, then do your own experiments.
These are the files that I have been using.
usrp_rx_cfile.py to write to file and usrp_fft.py and usrp_oscope.py for
realtime examination of the data and Matlab for post processing, based
on the utils in gnuradio-core.
