Let's now use the scope's Segmented Memory mode of acquisition to
selectively capture 25 consecutive occurrences of our trigger condition

Figure 37 Using the scope's Segmented Memory acquisition to selectively capture more
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 approximately 860 milliseconds of total acquisition time as shown

Push the horizontal position/delay knob to re- position the trigger point
back to center- screen.
Set the scope's timebase to 100.0 µs/div.
Press the [Run/Stop] front panel key to begin repetitive acquisitions
again.
Press the [Acquire] front panel key.
Press the Segmented softkey; then turn the Entry knob to select 25 as
the number of segments to capture.
Press the Segmented softkey to begin a Segmented Memory acquisition.
Press the Current Segment softkey; then turn the Entry knob to review all
25 captured segments.
Set the Current Segment to 25 and note the time- tag of the last captured
segment.
