The identifier byte consists of 6 bits for the frame identifier and two parity bits. This com-
bination is known as protected identifier.
Trigger
The R&S RTM can trigger on various parts of LIN frames. The data line must be con-
nected to an input channel, triggering on math and reference waveforms is not possible.
You can trigger on:
●
Frame start (synchronization field)
●
Specific slave identifier or identifier range
●
Data pattern in the message
●
Wake up signal
●
Checksum error (error in data), parity error (error in identifier)

Data
Sets the source of the data line. All channel waveforms can be used.
If the MSO option R&S RTM-B1 is installed, digital channels can also be used as source.
Remote command:
BUS<b>:LIN:DATA:SOURce on page 422
Polarity
Defines the idle state of the bus. The idle state is the rezessive state and corresponds to
a logic 1.
Remote command:
BUS<b>:LIN:POLarity on page 422
Version
Selects the version of the LIN standard that is used in the DUT. The setting mainly defines
the checksum version used during decoding.
