That makes me wonder if there's a market for a "civillian" version of a time-domain reflectometer (TDR). I know we used some very expensive ones to check striplines/cables for weapon components. Basically every impedance mismatch in a circuit will "bounce" a signal back - and in NW detonators we cared very very much about impedance.
Ours (many tens of kilobux) weren't from Fluke or the local big box store, that's for sure, but with today's tech you'd imagine one could get a 85% quality one at a doable price. Look at what's advanced in the thermal imaging in the last few decades - that tech used to be expensive voodoo and now you can get one that plugs into your iPhone.
