(o) In realfime sompling, oli the somples required to delineofe o
waveform are acquired in o single sweep, covering a single occurrence
of the woveform. Provides single shot r of a unique event. (b) In
sequenfiol sompling, points are r (with successively greater
deloy relative to the trigger event) on successive occurrences of the
waveForm, or on every nfh recurrence of the waveform. Digifol
sampling oscilloscopes use sequentiol sompling. Like (r below, if only
works with repetitive woveforms. (c) ...
