It's a fairly simple circuit. If you do a google search you should be able to find a few schematics for curve tracers that utilize an oscilloscopes X-Y function. At it's most basic you just need a 10v transformer, a few resistors, probes, and some BNC connectors like this one: . I'm planning on doing a little bit more of an elegant version that would use the PCs soundcard as the X-Y scope leaving my o-scope free. I've got a preliminary schematic using CMOS logic for control but it still needs some work and I'll probably use a PIC in the final product instead: .

Subject: [Electronics_101] Question around sound card curve tracer for William Kroyer
Hi William
In a previous post you discussed about a sound card based curve tracer. I
would request you to share information about the same.
I am looking for the following information
1) Is it a circuit you made yourself or did you buy it
2) What is the software for it.
I would request you to share the information around it with me.
Thanks
Regards
Gaurav
