To use LIN triggering
LIN (Local Interconnect Network) trigger setup consists of connecting the
oscilloscope to a serial LIN signal.
The LIN trigger will 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. A LIN
signal message frame is shown below:
1 Press the More key in the Trigger section of the front panel, rotate the
Entry knob until LIN is displayed in the Trigger softkey, then press the
Settings
softkey to display LIN trigger menu.
2 Press the Baud softkey to set the LIN signal baud rate to match your LIN
bus signal.
The LIN baud rate can be set to 2400 b/s, 9600 b/s, or 19.2 kb/s. The default
baud rate is 2400 b/s.
