USB-based test equipment...

800MHz sampling rate is pretty serious for a low cost analyser. 

My bad - that was for the Digital Discovery, not the Analog Discovery.

Still, that's an 800MHz 24-channel analyser with pattern generator etc. for USD 199. Uses the same Windows software that the Analog Discovery does.

The world has gone mad.

Only launched on March 17th this year - Press release: https://blog.digilentinc.com/new-product...discovery/

Logic Analyzer
