High Sampling Rates

Post by par100 »

Is it possible to to used X3XX or X4XX series with SDR Angel and sampling rates 100Msps or greater? It seems to be limited to less than 100Msps.
Thanks.

At the moment no. Can your PC actually keep up at 100MSa/s?

I've had limited success using an x410 with sdrangel. I'm still working through settings, etc... I'm running X4_200, and my hardware is quite capable of running the full 400MHz. I'm a dev, so i'm on the fence about pulling down the source and seeing what I can do to improve the stack.

Getting the device to initialize and "play", honestly, is the most tricky part.... it sometimes just refuses to initialize / start and i'm not entirely certain why. I'm actually trying to pin it down right now.

Either way, here's a view of HF :-)

If you're wondering...
at 10MS/s, single channel, app 357MBps

I get almost immediate overruns at anything over 15MS/s.
