Remote command:
BUS<b>:LIN:DATA:SOURce on page 419
Polarity
Defines the idle state of the bus. The idle state is the recessive state and corresponds
to a logic 1.
Remote command:
BUS<b>:LIN:POLarity on page 419
Threshold, Find Threshold
Set the signal threshold for the source channel. Enter a value, or use "Find Threshold"
to set the threshold to the middle reference level of the measured amplitude.
For analog channels, you can find the value also in the "Vertical" menu > "Chan-
nel <n>" >"Threshold"
For logic channels, you can find the value also in the "Logic" menu > "Threshold".

Version
Selects the version of the LIN standard that is used in the DUT. The setting mainly
defines the checksum version used during decoding.
The most common version is LIN 2.x. For mixed networks, or if the standard is
unknown, set the LIN standard to "Any".
Remote command:
BUS<b>:LIN:STANdard on page 419
Bit Rate
Sets the number of transmitted bits per second. The LIN standard defines a maximum
bit rate of 20 kbit/s.
"Predefined"
To select a bit rate from the list of predefined values, set "Bit rate" to
"Predefined" and select a value from the list.
"User"
To set another value, set "Bit rate" to "User" and enter a bit/s value.
Remote command:
BUS<b>:LIN:BITRate on page 419
12.6.3 LIN Trigger
Before you set up the trigger, make sure that the bus is configured correctly. See
Chapter 12.6.2, "LIN Configuration", on page 209.
To trigger on LIN signals:
1. Press the PROTOCOL key in the Analysis area of the front panel.
