I didn't dare to mention (ok i only didn't think of it ;-) ) the curve
tracer topic
as it is OT. But now, steve mentioned it, so i am innocent ;-).
I would like to have one to measure fets, bipolar and of course diodes.
I have a scope with lots of inputs, lots of X/Y possibilities and lots of
outputs
(sweep, trigger...) and also z in.
What makes most sense to build?
I would like to check the overall function, compare transistors to match
them (so it
should be a dual unit) and also measure diodes (like quick sorting zeners).
It should also get a "bias point" section where a dvm measures the voltage
(for sorting zener diodes)
The commercial units are to expensive, the TEK plugin is also not cheap
and it can't
compare i think.
I have analog storage (var. persistence and bistable) so it won't matter
if it is slow.
It is a analog scope so there is the problem with the writing speed, it is
not
very good to have huge diffences in it because the line gets hard to see
then (or you melt
the glass already where it is slow ;-) )
And of course - it should be cheap... very cheap..
what do you think? anyone built such a unit?
thanks
