For LIN 1.2 signals, use the LIN 1.3 setting. The LIN 1.3 setting assumes the
signal follows the "Table of Valid ID Values" as shown in section A.2 of the LIN
Specification dated December 12, 2002. If your signal does not comply with the
table, use the LIN 2.0 setting.
12 Press the Sync Break softkey and select the minimum number of clocks that
define a sync break in your LIN signal.
LIN Triggering
To set up the oscilloscope to capture a LIN signal, see "Setup for LIN Signals" on
page 335.
LIN triggering can trigger on the rising edge at the Sync Break exit of the LIN
single-wire bus signal (that marks the beginning of the message frame), the
Frame ID, or the Frame ID and Data.
A LIN signal message frame is shown below:
1 Press [Trigger] .
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob to
select the serial slot (Serial 1) on which the CAN signal is being decoded.
3 Press the Trigger: softkey; then, turn the Entry knob to select the trigger
condition:
• Sync (Sync Break) — The oscilloscope triggers on the rising edge at the Sync
Break exit of the LIN single-wire bus signal that marks the beginning the
message frame.
