well, I am going to order one this week sometime and need to make a descision. but I do have a few last questions. I don't really have a lot of experience with them and was wondering if all of the analog scopes could capture single events and display them. and what isthe trigger on a scope? what's a sweep trigger? also someone mentioned something about a surplus store or something near Columbia MO, I'm going up there soon and might want to check it out. Also, the tek tds 210...can I get any sort of waveform into my computer WITHOUT BUYING ANYTHING EXTRA? I will be doing stuff with the microcontrollers, but I will also be using this for other physics experiments so it can't be one of those logic dart things, which do look pretty niffty though. Also, does anyone have any company suggestions? I was thinking about ordering from future active which if I buy that tds 210 I get a fluke 79 meter for free. The other companies Iv'e called with these are the same price (995) but w/o incentive. I've also looked into some pre-owned scopes....are they safe? the only problem with those is that they all seem to be analog. well thanks Jonathan Newport
