The showstopper with the Bitscope is the sample rate, it's only 40MS/s, that gives an effective single shot bandwidth of only 4MHz.
They haven't really updated the design much in over a decade, so IMO it's no longer competitive.
It's optoisolated which is nice for PC scope, and it does waveform generation and logic too.
But US$700 for a 40MS/s 2 channel 8 bit mixed signal scope is way overpriced IMO.
On a side note, I can remember way back when Bitscope asked me to write their PC software for the them. Wow, that was a long time ago...
Sorry, I can't review any CAD software for conflict of interest reasons.
