Analyzing and Searching LIN Bus Signals (Option)
Analysis Source Field
You can analyze the following fields and patterns.
Break, Synch, ID, Data, Checksum
For the LIN frame format, see “LIN Bus Trigger” in chapter 4, “Triggering.”
Bus Setup (Setup)
Source (Source)
Set the analysis source to one of the settings below.
CH1 to CH4,* Math1 to Math4
* You can select CH4 when the key is illuminated.
Bit Rate (Bit Rate)
Select the LIN bus signal’s data transfer rate from one of the settings below.
1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps, User Define
If you select User Define, set the transfer rate in the range of 1000 bps to 20000 bps in 10-bps steps.
Revision (Revision)
Set the revision to one of the settings below.
• LIN 1.3: Only uses classic checksums, which only include the data field.
• LIN 2.0: Only uses enhanced checksums that include the protection ID. However, classic checksums are
used for ID = 60 (0x3c) to 63 (0x3f).
• Both: Uses both the enhanced check sum and the classic checksum.
Sample Point (Sample Point)
You can set the reference that will be used to determine the bus level in the range of 18.8 to 90.6% in 3.1%
steps.
Level (Level) and Hysteresis (Hys)
These items are the same as those of the edge search.
Auto Setup (Auto Setup)
Executes auto setup based on the specified sources.
The auto setup feature automatically configures the bit rate, revision, sample point, level, and hysteresis and
triggers on the LIN bus signal's Break Synch.
You cannot execute auto setup if the source is set to Math1 to Math4.
Decoded Display (Decode)
The colors that are used for the fields in the decoded display are as follows:
Break Orange (Orange)
Synch Pink (Pink)
ID Light green (Light Green)
Data Cyan (Cyan)
Checksum Light blue (Light Blue)
WakeUp Green (Green)
Start Bit Gray (Gray) fill
Stop Bit Gray (Gray) fill
Error Red (Red)
Timeout Error:
Displays a thick red line in the area where an error has occurred.
Framing Error:
Displays the words “Framing Error” in the field in which an error occurred using black
characters on red background. The instrument displays this error with higher precedence than
checksum, synch, and parity errors.
Checksum Error, Synch Error, Parity Error:
Displays the characters of the synch, ID, or checksum field in which an error occurred using
black characters on red background.
