For logic then a logic analyser is what you need. Are you talking
about some other category of hardware?
Printers, disk drives, data acquisiton. Logic analyzers are useful
beasts, but they don't tell you anything about the *quality* of the
signal (e.g. ringing, edges, etc.), although some have "glitch"
detection. But we don't live in an exclusively analog world.
Before DSOs we had analog storage-tube scopes.
