Re: [Discuss-gnuradio] gr-fosphor : New RTSA-like visualization block for GNURadio using GPU acceleration

[Mike Cornelius]

Hi Sylvain,

I had a chance to try it 'for real' this afternoon displaying live signals from a BladeRF source.

Let me just say WOW that's seriously impressive !!!!!

On my PC gr-fosphor handled the full 28MHz BladeRF BW beautifully.

I've used  R&S's FSVR and dare I say it, I reckon gr-phosphor is possibly better than the FSVR's visualizer, and MUCH more affordable.

Once again nice work.

Mike

Yes. I have a potential fix, just need to test it doesn't break OSX ...

It might be the disk read. The software reads from a file and it might
take a couple of iterations before the OS realizes it should cache the
file and pre-fetch it.
