Re: [Discuss-gnuradio] Gnuradio FFT - Graph concatenation

Hello Hassaan, there's no way you get 32MHz of bandwidth over network mode -- for 16 bit samples, that's not even theoretically possible over gigabit ethernet. In fact, the E310's CPU will under no circumstances push that many samples per second in or out of the E310. Please make sure you actually

What you want is very specialized, so you'll probably have to write something of your own for this. Tom I want to amplify on this point. The number of "useful things" you might want to do with a real-time sample-stream in the context of DSP and radio is very, very large, nearly infinite, and

Thanks for the guidance. Can I do this message passing in GRC? Also, how would the bandwidths get concatenated together and displayed in the same FFT graph? On Jun 11, 2015 7:08 PM, "Tom Rondeau" wrote: > On Thu, Jun 11, 2015 at 9:59 AM, Hassaan Ahmad > wrote: > >> Hi, >> >> I'm using USRP E310

Hi, I'm using USRP E310 and running uhd_fft.grc to acquire FFT spectrum from the device in network mode, and then displays that with QT FFT GUI block. Setting a center frequency, I can get an instantaneous bandwidth of 32MHz around the center frequency. (for me it's the maximum in network mode) N
