I ran my "record" setup for over 10 seconds, but when I run the data file back through my "playback" I only get about two seconds (if that) of result. What happened to all the data, and how can I change things next time to get all the data? My record setup is as follows: Rate: 50M USRP Source Low

Hi, I am playing around with gnuradio and I am trying to discover some basics. I did find a page with examples but the images seem to be missing. Am I looking on an outdated page or is there something wrong at the server side ? One of the pages which doesn't show the images is http://www.trondea

Thanks, Tom. Just to clarify, the 1Msps comes from the sample rate of 50M and the decimation of 50, correct? Also, is this going to record 10 seconds of "real-time" data? I was having issues with real-time, due to the large data stream, so will this record data from t=0 to t=10, just not in real-ti

Can I do that through GNU Radio, or is that a configuration I need to make through the USRP (ie Do I need to run the setup for the USRP)? Paul B. Huter On Nov 23, 2013 10:07 AM, "Tom Rondeau" wrote: > On Sat, Nov 23, 2013 at 11:02 AM, Paul B. Huter > wrote: > > Thanks, Tom. Just to clarify, the
