41 Press the [Trigger] front panel key; then press the Trigger Setup softkey.
42 Press the Trigger softkey and change to > (Greater than).
43 Press the Data softkey; then change value to 10 using the Entry knob.
44 Press the [Acquire] front panel key.
45 Press the Segmented softkey; then turn the Entry knob to select 100 as
the number of segments to capture.
46 Press the Segmented softkey to begin a Segmented Memory acquisition.
47 Press the Current Segment softkey; then turn the Entry knob to review all
100 captured segments.
48 Set the Current Segment to 100 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 700 ms of total acquisition time as shown in Figure 83.
Note that we can also view the decoded I

S data in the “lister” format,
and we can also perform Search & Navigation on the segments.
