buzzforb, I've done quite a bit of MOSFET testing in the past few years. I can at lest help you out witht the theory. I've probably done all the other tests though. Most were RdsON, Idsmax, SOA curve data, performance in switching applications, etc. Swithching stuff is not what we want but I understand all this raz ma taz pretty well...

Here is the basic comparison.
Measured across .1R 1% source resistor
They look pretty close, offset a bit, I guess you ideally want them to overlay each other or at least overlay the p channel?
Can you adjust something to get them to overlay, or are you pointing out that they are too different?

Began with traditional methods. Didnt start using curve tracer until after i verifed its performance against fets matched using traditional methods. Results are very repeatable using both methods. For curve tracer matching, i test them, sort them by Vgs and then retest again before final sort.
