Sounds a good idea. Any recommendations?Originally posted by Brandon@Sep 15 2005, 01:32 PM
There are programs you can buy for the PC that come with a probe and you basically turn your computer into an oscilloscope. If you have a laptop, you're good to go, light portable oscilloscope. Not only do you have the data there, very easy to export it from the program and into say excel to do some analysis or what not since its all on the PC.

Thanks. The web-tronics device looks quite interesting.Originally posted by Brandon@Sep 16 2005, 04:44 AM
From the basic crap to top line.
Web tronics specs for their PC osc. They aren't as limited as you think.Originally posted by tonykuphaldt@Sep 18 2005, 12:04 AM
I've used the free software that turns a PC's sound card microphone input into a crude scope. CRUDE is the operative word here. The resulting "oscilloscope" has a usable frequency range of (only) about 40 Hz to 10 kHz, no DC coupling option, an inherent phase shift between left and right stereo channels (at least with common sound cards), no overvoltage protection for your PC, and no calibration whatsoever on the vertical axis, just to name some of the more significant limitations. There are times when I use this in classroom demonstrations, but only under carefully "rigged" conditions where none of these limitations will be noticed. In other words, you already have to know how to use a scope in order to make sense of what the sound card scope is telling you.
