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.

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
. 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
time of 2 seconds. Note that the number of “found” events is indicated
near the bottom of the display. To automatically navigate to each LIN
error, press the
and
front panel navigation keys.
