Can You Do Component Testing On Digital Oscilloscopes?
nmoore:
I am in the market to getting an oscilloscope, I have see that the older analog cathode ray oscilloscopes (cro) are able to do component testing of different circuit elements (please see below). My question is do digital oscilloscopes have this ability? This feature seems good for electronic repairs as you can test components directly on a soldered PCB. I am new to oscilloscopes and trying to find a beginner oscilloscope that has this feature. Any assistance and recommendation is greatly appreciated. Thank you.

Most O-scopes whether analog or digital have XY mode which is what you need to get results like in your pictures.
artag:
The XY mode can be pretty awful on digital scopes though.
This may be because there's no obvious digitiser rate and no retrace period.
I've tried to use a scopetrex (rebuilt vectrex vector-plotted games machine) and even on a decent Agilent it looked poor.
alm:
This was a feature that was part of many Hameg analog scopes, and quite possibly other ones, too. You could replace it with any dual channel or more analog or digital scope that supports XY mode (which is pretty much all the serious ones) and what is often called an octopus component tester or curve tracer, which you could easily build and probably buy. See for example this video:

tested many zenner diodes and transistors like this ... we could saw the leakage ...
