Hey alan,
Thanks for the video, I've never stopped to think how the component test function worked (well actually I had, but I would've never of guessed it was so simple!). Brilliant! Just found out my DSO also has an XY mode (apparently called "versus"). Will miss the CRO built in tester...

I guess I'll need to find a nice little trasnformer and a write it down as another little project

I wonder if a variable frequency would be usefull, 50, 60, 100, 120, 400, 1000Hz...
