Oscilloscope, not oscillation overthruster

by Lee Ayrton <layrton@[EMAIL PROTECTED] > May 4, 2008 at 12:40 PM

I'm toying with the idea of buying one of these:

http://www.sciplus.com/singleItem.cfm/terms/10329

But I've never used an o-scope before (I'll learn.  I always do) and have 
questions.

The reason I want one is to peek at waveforms from the generator sets we 
use at work (typically 120/208, 1200 to 2400 amps, 3-phase, 60 Hz) and to 
see what sort of waveform mangling some of our less power factor-corrected

1.2 KW to 18 KW ballasts are doing.  Observing DMX* might be fun, too, but

not really necessary.  This one seem to be a nice entry-level, ****table (a

bench scope won't fit into my pocket for remote locations) and inexpensive

tool.  Through my innocent fog it seems to have the resolution and range 
that I need, but I dunno such stuff.  Nor do I know if I _can_ use this 
device on line voltage (remember: I've never used a scope before).

Advice, anyone?
