One that's attached to a Tesla coil spewing sparks and inducing stupid
voltages in any ground loop that happens to be in your measurement system.
Also handy for looking at gate voltages in the upper half of a bridge.

Anyway, I'm going off this whole diff amp thing, since I realized that the
CMRR depends on the matching of the two impedances (referred to the diff amp
box ground) you're probing, and they're unlikely to ever be matched in real
life. I'm going to investigate the optocoupler route instead.

What sort of microcontroller needs a 500 volt differential probe?
