Re: Scope grounding and generators

Sure, if you have one of those it is probably suitable as long as it's in good condition.

The point I was making was that the OP really should get the right tool, be it a scopemeter, a 222/222PS, etc. A laboratory oscilloscope is not the right tool for scoping high energy circuits. Just because you can doesn't mean you should!

Chuck Harris makes a great point...don't repeat mistakes that have already

the lives of very experience engineers. If you're going to be making
measurements on high energy sources, regular old lab scopes really aren't
the thing. Get yourself a Fluke Scopemeter. These are designed to safely
make floating measurements, and they have all the same protections that
you get in a normal high quality multimeter (especially, nothing that
might be live for you to accidentally touch).
Aren’t the venerable Tek 222, 222PS, and 224 also intended for that kind of
use, up to about 400 or so volts on the probes?
