USB-based test equipment...

Thanks for sharing the spec. It appears to be async sampling but perhaps I've missed something.

This is V1 - they continually develop - it'll only get better - the schematics are all on the link I posted above.

It's not something that would show on the schematic. I've looked here: https://reference.digilentinc.com/learn/...yzer/start

As far as I can see, there is no provision for using one of the inputs to act as a sampling clock for the others. This would be useful in many digital video audio and video applications where you know the sample rate, have a suitable clock available and aren't looking for glitches.

I agree that it's probably async only, but considering the firepower in there, I wouldn't be surprised is a V2 had synchronous capability. Probably about a year away I'd guess.

Adding synchronous sampling would only be a firmware update. The hardware is fully capable of doing it.

I'm informed by Digilent that they've had a lot of requests for this and that it will be added "soon"...

I knew you couldn't go cold-turkey on physical testgear, Nick!  This device is very tempting indeed.  All the hard work on Netview integration etc has been done.
And as you say, it's a lightyear away from cheap chinese dongles.
Do keep us updated as you discover more of its capabilities

Another toy:

That's a serious DMM, with Class IV safety rating to 600V. About £500 at a guess.

The manual is over 200 pages long...
