This morning, I was working with my scope, and I touched the CH1 BNC socket - ground side.
I thought I was dreaming.
I measured the voltage to AC Ground - 113VAC!!!
So something's leaking somewhere.
This is a 3 wire AC system - Live, Neutral, Ground.
I immediately checked my Signal Generator, on the same outlet - just fine, so it's definitely the scope.
Before I start poking around, does anyone have some fast pointers, to zero in on?
