CAN/LIN Triggering and Serial Decode

Setup for LIN Signals

LIN (Local Interconnect Network) signal setup consists of connecting the
oscilloscope to a serial LIN signal, specifying the signal source, threshold
voltage level, baud rate, sample point, and other LIN signal parameters.
To set up the oscilloscope to capture LIN signals:
1 Press [Label] to turn on labels.
2 Press [Serial].
3 Press the Serial softkey, turn the Entry knob to select the desired slot
4 Press the Mode softkey; then, select LIN trigger type.
5 Press the Signals softkey to open the LIN Signals Menu.
6 Press the Source softkey to select the channel connected to the LIN
7 Press the Threshold softkey; then, turn the Entry knob to set the LIN
8 Press the Baud Rate softkey to open the LIN Baud Rate Menu.
9 Press the Baud softkey; then, turn the Entry knob to select the baud

The label for the LIN source channel is automatically set.
signal threshold voltage level to the middle of the LIN signal.
The threshold voltage level is used in decoding, and it will become the
trigger level when the trigger type is set to the selected serial decode
slot.
rate that matches match your LIN bus signal.
The default baud rate is 19.2 kb/s.
If none of the pre- defined selections match your LIN bus signal, select
User Defined; then, press the User Baud softkey and turn the Entry knob
to enter the baud rate.
You can set the LIN baud rate from 2.4 kb/s to 625 kb/s in increments
of 100 b/s.
