Mmmm.. the software is slightly flakey, which I expected at this price point. Mostly it works rather well.

But with a captured waveform, and acquisitions OFF, one cannot zoom the waveform vertically. Horizontal zoom works, but not vertical zoom.

Also, when horizontal zoom is set at 50, 20, or 10ns/div, the horizontal scrolling no longer functions.

I think both of those are bugs, and I've emailed Thomas about them.

Cheers
