Re: Tek 576 Curve Tracer USB port to a cpu ... ?
Look at the inputs of the vertical and horizontal amplifier, assuming that they do not have an internal gain adjustment. That means that the vertical and horizontal amp chains have a fixed amplification factor from the input to the plates, and that all of the scaling is done at the sweep circuitry.toggle quoted messageShow quoted text
At that point, the sweep settings have basically set up the inputs for a particular p-p input voltage regardless of the settings for the current or voltage settings for the part.
What that does not figure in, nor does it (at this point) allow you to do is understand the settings on the dials for current/voltage. These are needed to reproduce the scale settings. No idea where to get them, of course.
There's ways, but they get interesting and you may not be able to do them easily. It depends on the circuitry inside, and all I'm working with is a "how it *should* work...."

I have an old 575 like the one your brother has. I think I might do a little exploration into the circuitry to see how one might drive a pair of A/D converters to get the horiz & vert data.
