Connecting the ground of the oscilloscope to the power line is not a good idea.? There are other ways to measure line voltage.? You can use an isolation transformer on the line, although that might

Did you connect the probe ground clip to anything on the outlet? If so, that could be the trouble that caused the current that tripped the breaker. You might have connected scope ground to 120VAC.

Hi Kerry, A digital scope will have severe aliasing when you hit any frequency from the SG504 that is a subharmonic of the DSO's sampling frequency. That would account for severe noise and a drop in

I'm embarrassed to say that the apparent problem with the SG504 seems to have more to do with operator error than any real fault. The Lecroy DSO being used to look at the SG504 output has only

I'm blown away by this. I had seen these, but thought they were equipment specific.? Many must be, but what a great idea.? And if cosmetics aren't critical they seem available? (used) on Ebay for

Hmmm... Good ideas from you all! What works for me at the moment is a wooden bench in my garage. I made an equipment shelf for it a few years ago. Then a couple months ago I put casters (a few bucks

I am working on a tek 371 with a friend of mine , it has no test fixture and these things are never seen on ebay , so our idea is to make one . We are in the process of using a test fixture which will
