Yeah I figure with the soundcard o-scope software I could probably get some somewhat decent readings but really that's not my goal. I'm more or less just looking to use mine for reference. ie spotting bad/leaky caps, diodes, and transistors. The nice thing about doing it with a PC is that I could take screen captures of good signatures for various components and use them for comparison against a suspected bad one.

The circuit was also verified by the group. The problem is that though I would get the look of the curve the values in the graph did not have ay number assigned to it. Thus it will be nice to have a curve tracer which would be computer controlled in its plot. Gaurav On 10/7/06, Roy J.
