Keysight application note regarding component testing with scopes

(1/1)

Cheagor:
Hello everybody,

I have recently acquired a Keysight DSOX1102G. Now I've found this application note by Keysight that gives an example of how to test components with the built-in signal generator.

Now I originally wanted to build myself something so I can plot IV curves on my scope, but this seems to be an alternative solution. Would I be missing out on something if I used that the application notes solution instead? Technically, it doesn't measure current but does seem to give general information about the health of a part.

I would love to know your opinion about this.

Here is the application note I am referring to:

Best,
Phil

Here's another way to do it using the built-in function generator.  Again, isn't perfect since the current sense voltage is added to the DUT voltage, but it works pretty well and is easy to do.



and a simple way to measure capacitors and inductors:



Cheagor:
Thanks! I already have found those videos.

I would very much like it though, to have the simplest setup that I can get away with, because I am traveling a lot with the scope. If IV gave me something that Trigger/V or V/V, I'd still consider doing it, but if I do, I want to know why I'd need it.

Now the way I understand it, is that the use of the external trigger of the signal generator (trigger is built in) makes it possible to observe phase differences. When component testing with an IV Curve, it seems that the predominant factor to determine for example the health of a capacitor would be to look at phase. For that, measuring the I, doesn't seem entirely necessary.
