4 Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs
Segmented Memory optimizes oscilloscope acquisition memory by only
capturing important segments of a waveform based on the trigger
condition and timebase setting. In this example, we have selectively
captured approximately 15 seconds of total acquisition time as shown in
Figure 77. Note that we can also view the segmented decoded LIN serial
data in the “lister” format, and we can also perform Search & Navigation
operations on the captured segments.
35 Press the [Serial] front panel key; then press the Lister softkey.
Because we performed the Segmented Memory acquisition based on
triggering on LIN frame ID = 21
HEX
(or perhaps you changed the trigger
condition to trigger on ID = 12
HEX
), our Lister display now shows a list of
consecutive occurrences of just this particular frame ID as shown in
Figure 78. To find out how often the parity bit or checksum errors occur
during this particular frame, you could manually scroll through the list, or
you could use the scope’s Search & Navigation capability to locate all
occurrences of errors.
Figure 78 Lister display shows 500 consecutive occurrences of one particular LIN frame.
