12 Press the Standard softkey; then, turn the Entry knob to select the LIN
standard you are measuring (LIN 1.3 or LIN 2.0).
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.
13 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 343.
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 or Serial 2) on which the CAN signal
is being decoded.
