I don’t have a traditional oscilloscope, but I do have a Fluke 123 Scopemeter that I bought about 13 years ago. I don’t work on the type of equipment I used to anymore, so I find I have very limited uses for it with regular electrical work. You can use it for things like peak and nominal voltage reading, looking for waveform distortion and for extended monitoring with the software package, but I think a decent power quality meter would probably be more useful for troubleshooting building electrical systems.
I work alone often, so one tool I find that comes in handy is the Ideal digital breaker finder. It saves me a lot of trips back and forth or up and down stairs to the panel to shut off a circuit.
Of all the other various fancy circuit tracers, locators, TDR, cable and network testers that I have, I still find that my trusty Fluke 337 clampmeter, cube tester and PE/Tempo toner/filter probe set are my go to tools of choice the for majority of circuit tracing and troubleshooting issues.
