As you scroll through the data, note that waveforms “track”. This means
that the frame that the arrow points to in the lister table corresponds to
the waveforms that are positioned at center- screen. If you want to zoom
in on a particular LIN frame of data, tap the Zoom to Selection softkey.
Looking for infrequent errors in this long decoded record can be difficult.
So let’s now perform an automatic search to find all occurrences of errors.
We will then automatically navigate to each of these error conditions.
21 Push the horizontal position/delay knob to re- position the trigger point
back to center-screen.
22 Set the scope’s timebase to 200.0 ms/div.
23 Press the [Search] front panel key.
24 Tap the Search Edge softkey; then select Serial 1 (LIN).
25 Tap the Search for softkey; then select Errors.
The white triangles near the top of the waveform area mark the time
location of each “found” occurrence of our search operation as shown in
Figure 76. These frames are also marked in orange in the first/pointer
column of the lister table. Your scope should have found and marked more
than 15 occurrences of this search operation based on a total acquisition

occurrences of LIN errors over a 2 second time span.
