46 Press the [Run/Stop] front panel to begin repetitive acquisition again.
47 Press the [Acquire] front panel key.
48 Press the Segmented softkey; then turn the Entry knob to select 500 as
the number of segments to capture.
49 Press the Segmented softkey to begin a Segmented Memory acquisition.
50 Press 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.
