The stuff I work with makes it pretty easy. If a thyristor is iether
beinggated falsely by noise or is being falsely commutated, it shows on the
Ac waveform on the scope. When I want to see if it's affecting the
microcontroller or any part of my logic circuitry I connectthe Bitscope. A
favorite test I now have is to use the bitscope with one analog channel on
various points after my 5V (or 3.3V) supply while watching for hiccups like
bit flipping, etc with the digital channels. I suppose checking another
nearby device would be equally as interesting...

It's like the tree falling in the forest thing again....If I can't hear it,
it didn't make (enough) noise.
