As always, thank you, Marcus. I am thinking about getting rid of the graph (and throttle, now), and making another setup to run the output file from the original (through a throttle?) to the graph to look at smaller pieces. I want to be able to look at (say) 5MHz-10MHz, so my plan is to set the FFT to be 5MHz centered on 7.5MHz. However, I am not sure if that is correct. But - first step is to get my data.
Thanks, again, Marcus. Paul B. Huter On Nov 17, 2013 5:41 PM, "Marcus D. Leech" <mle...@ripnet.com> wrote: > I am running a USRP source through a throttle to an FFT sink and a file > sink.
