i received this 6022be scope 1 week ago, done some basic testing, as many other said, ok hardware but bad software (crappy actually). the most annoying thing is the scroll on the a single shot. for eg. i set it to 500ms/div, it records the signal, you zoom in after, and you want to center the segment you want to see more details, this is where it gets ugly, cause you have to drag with the mouse left/right, and most of the times it refuses to do that. maybe it's my windows (7 64bit) or my monitor 1440p resolution, but i find the software to be useless anyway....
i am using it to trace an kwp2000 signal (~10kbps) so for this use it's enough 40msps , actually it's 1msps on longer timebase...
