Let’s now use the scope’s Segmented Memory mode of acquisition to
capture 500 consecutive occurrences of the LIN frame that the scope is
currently set up to trigger on (either ID = 21
HEX
or ID = 12
HEX
). But to
complete the rest of this lab your scope must be licensed with the
Segmented Memory option.
27
Push the horizontal position/delay knob to re- position the trigger point
back to center- screen.
28
Set the scope’s timebase to
1.00 ms/div
.
29
Press the
[Run/Stop]
front panel to begin repetitive acquisition again.
30
Press the
[Acquire]
front panel key.
31
Press the
Segmented
softkey; then turn the Entry knob to select
500
as
the number of segments to capture.
32
Press the
Segmented
softkey to begin a Segmented Memory acquisition.
Note that capturing this many consecutive occurrences of this particular
frame will take about 30 seconds.
33
Press the
Current Segment
softkey; then turn the Entry knob to review all
500 captured segments.
34
Set the
Current Segment
to
500
and note the time- tag of the last captured
segment.
