So as to not thread-jack the F5, here's the JFET tester I've been working on. It uses the Measurement Computing PMD1208LS USB data acquisition thingy:

so program takes USB data input of signals
and processes according to some configuration settings

Will you use this only for personal use?
.... or will you publish hardware description/software download
as a project for others to builld?

I was looking at these months ago and i asked if one of these could be used for FET matching and everyone pretty much told me no. So i am definitely interested in know how and what and full details of your setup please!

The same idea can be applied to MOSFET's -- I did it with tubes -- just somewhat different stuff to look.

The code is VB.NET, but the DAC/ADC's are from MCC and so are the softwire modules which drive the PMD1208LS.
