decoded record can be difficult. So let’s now perform an automatic search
to find all occurrences of Error Frames and “form” errors (non- flagged
error conditions). We will then automatically navigate to each of these
error conditions.
23 Push the horizontal position/delay knob to re- position the trigger point
back to center-screen.
24 Set the scope’s timebase to 100.0 ms/div.
25 Press the [Search] front panel key.
26 Tap the Search Edge softkey; then select Serial 1 (CAN).
27 Tap the Search for softkey; then select All 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 70. 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 10 occurrences of this search operation based on a total acquisition

occurrences of CAN errors over a 1 second time span.
