Oscilloscope recommendations?

[Talyn]

I'm thinking about buying an oscilloscope for automotive testing. I can get a nice analog one for under $200, but it doesn't record, its big, and it doesn't operate off 12v. So it wouldn't be that great for automotive work. I am thinking about a PC USB unit. I have seen the Pico setup, but that is a little out of my price range. Any usable ones for around $200?

I guess I would check ebay. I think you'll have a very hard time finding a scope that runs on 12 VDC.

Unless you understand the ins and outs of a digital scope, I would stick with an analog scope. The problem with digital scopes is aliasing. Because of the sampling rate of the scope, it can generate artifacts that can fool you.

An analog with logging is out of my price range. That is a feature I would need for driveability issues. I would prefer not to have to stare at a screen instead of driving.

I use the snap on digital oscope. Its alot more then 200,so I dont recomend it. I do agree with oldman, a digital scope can confuse people if they dont fully understand it.

See Nyquist theorem as a theoretical starting point.
As a rule of thumb we always choose a sample frequency of 10x the highest expected signal frequency for A to D cards.
Do check out ebay. I just did a search and there are a few pockt scopes
that are < $200.
