The scope should have just captured 500 consecutive occurrences of this
burst. Let's review them.

Figure 18 Using Segmented Memory Acquisition to capture more waveforms with high
Along with capturing consecutive low duty cycle signal bursts, the scope
also "time- tags" each segment/waveform so that you know the time of each
capture segment/waveform relative to the first captured
segment/waveform. Time- tags are shown in the lower left- hand corner of
the display. Segment #500 should have a time- tag of approximately 2
seconds along with a time- of- day stamp as shown in
captured waveform should also have very high resolution because the
scope used a high sample rate to capture each waveform. If you attempted
to capture ~2 s (200 ms/div) of time- span using the scope's Normal
acquisition mode, the scope would have significantly reduced its sample
rate and thereby would have provided extremely poor sample resolution on
each burst.

Press the [Acquire] front panel key (near the Cursors knob); then press
the Segmented softkey (only available if licensed with the SGM option).
Turn the Entry knob until # of Segs = 500.
Now press the Segmented softkey to turn on this mode of acquisition.
Press the Current Seg softkey; then turn the Entry knob to review all 500
waveforms.
Now set the Current Seg = 500 using the Entry knob (last captured
segment/waveform).
