Attached is a couple of pictures of some 7587 Nuvistor testing I did
w/ a stock 575 curve tracer, if you want a feel for what you can "see"
with one.
One picture is a tired old 7587, the other one is a NOS one. Curve
settings were the same between them. (But I've forgotten what they
were now. :-> ) Hopefully the list won't strip them off. The
pictures are a little fuzzy, but they'll do.
There's a Measurements Concepts PDF book out there. "Semiconductor
Device Measurements" by John Mulvey that has all sorts of measurements
you can make using a curve tracer. Its pretty generic, and not
specific to any certain tracer. Unsurprisingly its semiconductor
specific, and does not have any specific vacuum tube section. I've
forgotten where I picked my copy of the PDF up, but thanks to whomever
had it posted.

Anybody know of a good video tutorial, or a good read with lotsa
pictures of how a curve tracer is actually used, what the display is
actually showing me, examples of both good and bad components under
test, and nifty things to do with a CT that you normally wouldn't think of?
All I really have at the moment, along the the 7CT1, is the manual, and
it has a few diagrams of typical traces, but really doesn't go into much
depth on explanations. ?I'm presuming when Tek wrote the manual that Tek
presumed a modicum of knowledge of the operation of a curve tracer, but
for someone who hasn't used one in the past, the manual doesn't quite go
far enough, at least for me.
Thanks,
