Well, feel free to PM me  ;)

Hi,

I do it using SMUs. My SMUs are Keysight B2902A and B2962A. Why do I do this:
- I need precision for the base voltage (e.g., for Gummel plots)
- The measurements must be pulseable to mitigate device heating at higher powers
- I also need wide range current measurements (0.x uA to several 100mA)
- The data is imported to a PC and all the curves are made there using Python.
  (I have output curves, like a normal curve tracer, Gummel plots, beta curves, ...)
- The imported data is used to create SPICE models.

An analog curve tracer is nice to make quick measurements or go/no go tests. I have not built, but I like a nice
project from Changpuak (complex curve tracer) or the Curve Tracer Arduino shield.

You can still get it from ELV

I've built one this year, its quite capable. Although I do still have some issues that I need to resolve.

kripton2035:
elv don't sell anything outside of germany/austria/swiss.
I bought from them years ago, now it's impossible.
they have now a french store elv.fr, but there are quite nothing in this store, only their domotic line.
it was a great shop, it's even no more european !
