BK Precision 2194 - LIN Trigger

Serial Trigger and Decode 81
7.5.2 LIN Trigger
This section provides a brief introduction and description for the operation of the LIN trigger.
Trigger Condition
• Break — the oscilloscope will be triggered at the position of break eld’s break delimiter.
• ID (Frame ID) — the oscilloscope will be triggered at the position of identier eld’s stop bit, if the value of a frame’s
ID is equal to specied value. (Note: If the data’s value is 0xXX, any data value will be matched)
• ID + Data (Frame ID and Data) — the oscilloscope triggers when a frame with an ID and data equal to the selected
values is detected. Use the Universal Knob to select the value for the ID, Data1 and Data2.
a. The ID’s value is the same as set value.
b. If you have set either Data1’s or Data2’s value, and the signal has a data is the same as that value. If you have
set both Data1’s and Data2’s value, the signal should has two consecutive data, the rst data’s value is Data1,
second data value is Data2.
Note:
If the data’s value is 0xXX, any data value will be matched
• Data Error —the oscilloscope will be triggered when errors (such as ID check error, checksum error, sync byte eld
error) are detected.

• If you select ID condition:
– Touch ID and set its value by turning the Universal Knob.
• If you select ID+DATA condition:
– Touch ID and set its value by turning the Universal Knob.
– Touch DATA1 and set its value by turning the Universal Knob.
– Touch DATA2 and set its value by turning the Universal Knob.
