Re: [Discuss-gnuradio] Viewing square wave in usrp_oscope

Hi, Sorry for the previous mail. Totally out of context. I gave a square wave input direct from a signal generator and the behaviour of usrp_oscope was the same as I had explained before. I increased the frequency to way above 100KHz. Is there any other option to be given? Regards Sudhindra >

I am also in the process of studying this part of the software to see if I can use it to recreate my data from the demodulated signal. Can anyone provide information on what are sync field, seq number and command field that are added to the payload? I need to recreate this in my transmitter which

[Discuss-gnuradio] Displaying the Magnitude on the scope

2005-11-17 Thread Robitaille, Michael
I now able to demodulate my signals and would like to view the magnitude of the output rather than the real/img.  I tried to use the gr.complex_to_mag() operation and feed it in the scope_sink_f but I get a blank scope screen.   u_mag = gr.complex_to_mag() self.connect(u_xlated, u_mag)
