I'm working on an 7B53N but I think this question applies to many/most scopes and/or time-bases.
In AUTO mode, the time-base is in a "free-run" mode which generates a ramp at the selected sweep rate and, at the end of the ramp, generates another ramp. This continues whether a trigger is present or not.
In NORM, the time-base waits for a triggering signal before executing a sweep and, at the end of the sweep, waits for another trigger signal before generating another ramp.
My question is with respect to triggering in AUTO. Since the ramp will be generated regardless of a trigger, how does the system perform triggering when in AUTO mode?
I know this is a very basic question, but I don't seem to be finding a good explanation in the manual so I thought I'd ask here.
Thanks,
