Hi Ralph,

The "AC trigger" function will lock the scope in sync with the AC line.
However, the gap tends to "jitter" in it's firing timing by say +-250uS.
That will totaly obscure the signals at say 10uS/div.  I would set the
scope on normal trigger and look for that big initial spike for a trigger
signal.  I am sure you have already pretty much figured all this out ;-)

Cheers,

	Terry
