How can I inspect AC mains signal on my +/-5v scope?

by Kasterborus <kasterborus@[EMAIL PROTECTED] > Aug 7, 2008 at 11:09 AM

I need to find a way to couple the AC mains signal to my low voltage
scope input. I'm adjusting a rotary spark gap and need to get the
"bangs" on the up and downswing of the AC cycle.

Is there something I can build with a transformer / optoisolator - or
is it easier than that?
