48 Tap the Segmented softkey; then tap # of Segs and enter 500 as the
number of segments to capture.
49 Tap the Segmented softkey to begin a Segmented Memory acquisition.
50 Tap the Current Segment softkey; then turn the Entry knob to review all
500 captured segments.
51 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 over 4 seconds of total acquisition time as shown in Figure 59.
Note that we can also view the decoded SPI data in the “lister” format,
and we can also perform Search & Navigation on the segments.

SPI traffic.
