Hi Bill, It depends what you need/want. There are issues with the PC based 'scopes. Most obvious to the user is response time. It can be fustrating to have the screen change a second after the event happened! Other issues are sample rate and input voltage range. The Bitscope headlines "100MHz analog bandwidth" but you have to big a bit deeper to find "up to 40Ms/s". Seems like they are wasting most of the bandwidth if the have an anti-alising filter. This is really only usable to 20MHz single shot. I could not find the input sensitivity and ranges. I looked at the BitScope a while ago and decided it was overpriced at $600. I was lucky to find an HP 54645D for the same money. Unless you need the PC connnectivty and simple logic analyser (the 54645D gives both ;-), I'd look at a conventional 'scope. As you are considering a PC 'scope, have a look at the Pico Technolgy range, http://www.picotech.com/oscilloscope-specifications.html Their bandwith / sample rates make more sense. I've used their products and they work very well.

Although I've been aware of PC scopes, I never really looked into them. The specs look pretty good (the fact that I was looking at an entry-level Tek will give you some idea of my needs). Anyone have any experience with BitScope or other of the low-end PC scopes?
