3 Advanced Triggering, Search & Navigation, and Segmented Acquisition Labs
Your scope should now be triggering on just setup time violation
conditions similar to Figure 42. With this unique trigger condition,
perhaps we can now correlate these signals to other signals and/or activity
in our system that may be producing this timing problem.
Let’s now use the scope’s Segmented Memory mode of acquisition to
capture 500 consecutive occurrences of a setup time violation. But to
complete the rest of this lab your scope must be licensed with the
Segmented Memory option.
10 Press the [Acquire] front panel key.
11 Tap the Segmented softkey; enter 500 as the number of segments to
capture.
12 Tap the Segmented softkey to begin a Segmented Memory acquisition.
13 Tap the Current Segment softkey; then turn the Entry knob to review all
500 captured segments.
14 Set the Current Segment to 500 and note the time-tag of the last captured
segment.
