Oscilloscope Ground Issue
Im trying to scope a TV signal. Where should I ground the probe's
ground? Over the common ground on the PCB board? Isn't that a floating
ground?
There seems to be 30V ac with reference to the scope ground when I use
a VOM to measure voltage. Will it blow or damage the scope? Anyway to
prevent sending live current down the scope ground and blowing it up?
Thanks.
