10 CAN/LIN Triggering and Serial Decode

Setup for LIN Signals

LIN (Local Interconnect Network) trigger setup consists of connecting the
oscilloscope to a serial LIN signal.
To set up the oscilloscope to capture LIN signals, use the Signals softkey
which appears in both the Trigger Menu and the Serial Decode Menu:
1 Press [Label] to turn on labels.
2 Press [Trigger]; then, select the LIN trigger type.
3 Press the Signals softkey. The LIN Signals Menu will be displayed.
4 Press the Source softkey to select the channel connected to the LIN
5 Set the trigger or threshold levels to the middle of the LIN signal.
6 Press the Baud softkey to set the LIN signal baud rate to match your
272
signal line.
If you have connected one of the oscilloscope's analog source channels
to the LIN signal, adjust the trigger level for the selected analog channel
to the middle of the waveform by turning the Trigger Level knob.
If you have connected one of the oscilloscope's digital source channels
to the LIN signal (this applies to MSO model oscilloscopes only), press
the [Digital] key and select Thresholds to set an appropriate threshold
level for digital channels.
The value of the trigger level or digital threshold is displayed in the
upper- right corner of the display.
LIN bus signal.
The LIN baud rate can be set to 2400 b/s, 9600 b/s, 10.4 kb/s,
19.2 kb/s, 115.2 kb/s, 625 kb/s, or User Defined. The default baud rate
is 2400 b/s.
If the desired baud rate is not shown in the list, select User Defined. You
can set the LIN baud rate from 2.4 kb/s to 625 kb/s in increments of
100 b/s. Press the User Baud softkey and rotate the Entry knob to make
your selection.
