wait a minute..... there was only 1 full o-scope there, i can't remember what the smaller ones were but they had waves as well
Your HS had an electrical engineering class with O-scopes? Wow...I wish my HS had that opportunity...

Don't inhale the solder fumes! They make you verrryy.....sleeeeeepppyyyy....zzzzzzzz.

They're not toxic though.

Wait you do need the crazy 50W wirewounds in parallel don't you?

Regulated load?

yeah... it got cut because it was above 90% of the brainless twits at my high school's heads... the teacher never liked me that much.... he quit when the course got cut, and.... i believe the school still has those... not the full O-scope, the teacher took that... he payed a but load for it,

50w? we had tons of those.... we had resister boards(don't remember the name for them) and we had 100w resisters, and 150w...... i don't remember what that huge one was.... needless to say the teacher took all of those when he left as well, those all came out of his pocket....

edit: i just remembered the small ones were 5-25w, we had tons of THOSE we had a few 26-40w ones, 4 50W ones, 1 100w one and 1 150w one oh and they were in ohms.... i forget stuff....

I believe so. Phaedrus or Tator Tot would be the ones to ask that though. I was using the scopes on automobile and ham/cb radio equipment. I never used one on a high powered psu like what we have in a computer.

just to clarify.... the oscilloscopes we had in class looked similar to this:


but the teacher's O scope looked like this:


and we had ammeters( i think they were digital multi meeters)

I've been looking into this: http://www.seeedstudio.com/depot/pre...html?cPath=174

It has enough bandwidth for testing PSUs. I'm not sure about the accuracy, but the general feedback has been good. Not sure how "heavy duty" it is either.

Phaedrus, Tator Tot, or JonnyGURU would probably be able to tell you if it could.
