Post by thread:Cheap but functional oscilliscope

I am in need of a cheap, but functional oscilliscope. It can be stand-alone or driven by a PC. I really only NEED dual channels, the ability to measure up to about 300 VAC and down to a few milivolts DC, and reasonably fast signal measurements. I'm working almost entirely with PIC chips running less than 20 Mhz at the moment. What I'd love to have is a full 8- or 16-input digital logic analyzer with two analog inputs along side it, but I'm probably quickly leaving the realm of my budget. This is more of a query for what you're using, and about how much I should expect to spend. I can afford $400, but $1000 is a bit much without it being ultra-cool enough to convince my fiance that it's worth me forking out that much for a hobby. Thanks, --Michael

If you live in the US, try Ebay and say a pray before buying. If you live in the Europe, then will be a few times more expensive using the same Ebay. But in both situation a second hand oscilloscope could be a better choice than a new one. cheers, Vasile On 12/4/05, M Graff <spam_OUTexplorer-piclistTakeThisOuTflame.org> wrote: {Quote hidden}> I am in need of a cheap, but functional oscilliscope.

Was looking at that listing, and realised how little I know about them. Anyone got any good links that'll describe how a logic analyser like that HP works and what they can do? I've already got a Bitscope DSO/logic analyzer and use it a lot, but it looks like it's a pretty simple peice of equipment compared to that HP stuff. Love to learn more about how the "real world" does logic analysis. -- EraseMEpetespam_OUTTakeThisOuTpetertodd.ca http://www.petertodd.ca
