Re: Yet another use for a curve tracer
I don't have a BK 501 but I do have a B&K 540 "Component tester". It's atoggle quoted messageShow quoted text
small AC powered unit with about a 2 1/2" CRT. The whole thing is about 7
inches wide and about 2 1/2" tall and about 10" deep. IIRC it has two
current ranges and two voltage ranges and it's strictly an I-V tester so
it's not nearly as accurate as the Tektronix curve tracers but it is a
*very* *handy* device to keep on the bench for quick testing of
semiconductors and for identifying passive devices. IIRC it's the same or
very similar to the Polar T1200 component tester.
I have the manual for a B&K 501A and it looks like a decent unit but it
doesn't the capabilities of a Tektronix Curve Tracer but it will display
multiple current steps. It would also be easy to add a variac to it to get
the continuously variable collector voltage capability.
I also have a Hicock unit similar to the B&K 501 but it also has the
capability of testing vacuum tubes. I'm looking for a manual or even just
the specs for it if anyone has them.

Does it not need a minimum load. I just hook them up to the AC cord
