I'm getting to the point where my projects are involving lots of switching power circuits and I probably need to get my own oscilloscope. Prior to this I mainly needed an oscilloscope as a logic analyzer but that got old really fast and went out and bought one.
The main issue is there are used analog scopes out there with really good bandwidths and 4-channels, perfect for hunting down waveform problems and transients in 3-phase switching circuits. The only problem is that they can't catch single shot events, so no observing startup waveforms or startup transients. But for the same money, getting this single-shot capability comes at the cost of reducing the scope down to 2 channels with almost 7x less bandwidth.
I'm curious as to the experience of those who have worked with switching power circuits a lot and how often they had to turn to single-shot capture modes.
