I have a Bitscope 310U as well, and I'm quite happy with it. Sure takes a lot less bench space that the CRO I used to have! But as with anything, it depends on what you need. I'm a hobbyist, so my needs are simple and the Bitscope satisfies them well. I agree with Marcel that sometimes you'll see a staircase, but generally I can switch to a lower voltage range and avoid it. And personally I have no problem with the UI. Not as intuitive as twiddling knobs on a real 'scope, but I find it quite usable. I find that the 2 analog and 8 digital channels fits my needs well, the sample rate is more than adequate for me, as is the buffer size. I'm sure a lot of PC-attached scopes have the same features, but I like having "PC" features like FFT and dumping captured waveforms and screen grabs - something you pay a lot more for on a stand-alone scope. If my Bitscope died, I'd buy another one, no question. Regards, David Meiklejohn Marcel Birthelmer wrote: > Hi Bob, > yes, I do.
