Can You Do Component Testing On Digital Oscilloscopes?
FrancisM:
This is what you can expect from a well known brand on this board, pretty usable.
I wanted to show the effect of using high voltage transistors in a Wilson current mirror or cascoded at a very low Vce.

I would say a curve tracer and a component tester (subject) ist something complete different isn't?

Swainster:
I think that the OP is talking about analog signature analysis rather than what is typically understood by the term curve tracing (at least in the sense of accurately characterising a particular component). ASG can be done on a populated board, but then it tests the characteristics between 2 circuit nodes rather than a specific component. Of course, this characteristic may well be dominated by a particular component, but this isn't always the case. The main thing is that by comparing the signature between a good board and bad one (or from a reference document), it helps to locate a fault in a circuit.

You don't need Z-axis control for one thing, and that's probably the most important. The only remaining issue would be getting your acquisition period right and I think very fast and short might be good enough for a 60Hz or 1kHz based component tester.
