Set the Current Segment to 500 and note the time-tag of the last captured
segment.
Segmented Memory optimizes oscilloscope acquisition memory by only capturing
important segments of a waveform based on the trigger condition and timebase
setting. In this example, we have selectively captured 500 consecutive occurrences
of this burst for a total acquisition time of than 40 ms as shown in Figure 28 . The
scope did not waste valuable acquisition memory capturing signal idle time
between each burst. But the scope does provide us with timing information about
the time of each segment relative to the first captured segment. As you were
reviewing each captured segment, you should have determined the glitch occurs
every on 40th occurrence of the burst.

consecutive occurrences of a burst of pulses.
