35 Tap the Segmented softkey; double-tap on # of Segs and set the value to
500.
36 Press the Segmented softkey to begin a Segmented Memory acquisition.
37 Tap the Current Segment softkey; then turn the Entry knob to review all
500 captured segments.
38 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 approximately 20 seconds of total acquisition time as shown in
Figure 54. Note that we can also view the decoded I

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