Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs
Let's now use the scope's Segmented Memory mode of acquisition to
capture 25 consecutive occurrences of the LIN frame that the scope is
currently set up to trigger on (either ID = 21

Figure 60 Using the scope's Segmented Memory acquisition to selectively capture 25 LIN
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 750 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 1.00 ms/div.
Press the [Run/Stop] front panel to begin repetitive acquisition 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.
