You can do that without -any- storage scope. I worked on switchers for many years without ever needing a storage scope.
Can't do much about that. (although TEK had a color LCD mod that generated separate colors for an analog scope display.)
You can use a camcorder and a VCR to "store" intermittent events on an analog scope,or you could use a PC and PC cam the same way;in fact TEK used to sell just a system. DCS-something.
the really nice thing about digital scopes is their waveform processing power.FFTs and the like.
