h. ID and Data
：
The oscilloscope will be generated on data frame that matches the specified ID.
i. End of Frame
：
It will be generated on the end of frame of CAN-FD signal.
j. Loss Confirmed
：
It will be generated on loss confirmed of CAN-FD signal.
k. Bit stuff error
：
In the segment that requires bit filling, the waveform will be triggered when continuous
detect the error from the same level of 6 bits.
(2)
Frame Format
It is valid when trigger condition is “identifier” or “ID & data”. It can set “standard format, extend format,
FD standard format and FD extend format”. Different frame format has different ID range value. “Stand
format, extend format” is suitable for CAN signal; “FD standard format, FD extend format” is suitable for
CAN-FD signal.
(3)
ID Value
It is valid when trigger condition is “identifier” or “ID & data”. It can set ID value, the range is 000
～
7FF,
00000000
～
1FFFFFFF.
(4)
Data
a.
Byte Length: set the byte length of data to be triggered. Different byte length has different data
range. The byte length rang is 1
～
16.
b. Data: Set data to be triggered, the range can set to 00
～
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.
c. Bias
：
Set the data bias of byte data for delay trigger, it can set on or off. when it is on, display the
“byte bias” menu and the bias range is 0
～
63; when it is off, hide the” byte bias” menu.
(5)
Decoding Setting
Quickly enter the entrance of CAN-FD protocol decoding, refer to reference protocol decoding
“CAN-FD
Decoding”.
7.19 LIN Trigger
LIN decoding trigger can set trigger condition, trigger coupling, trigger mode and decoding setting.
(1)
Trigger Condition
LIN trigger condition can set synchronization, identifier, data, ID and data, wake-up frame, sleep frame
and error frame.
a. Synchronization: The oscilloscope will be generated when detect the synchronizing signal.
b. Identifier
：
The oscilloscope will be generated when detect ID is equal to the setting frame.
c. Data: Waveform will be generated when the sampled data by LIN protocol is in accord with user-
defined data. It can help user quickly find the transmission signal of the specific data that interested.
d. ID and Data: The oscilloscope will be generated when detect ID is equal to the setting frame.
e. Wake-up Frame: The oscilloscope will be generated on wake-up frame of signal.
f. Sleep Frame: The oscilloscope will be generated on sleep frame of signal.
g. Error Frame: The oscilloscope will be generated on error frame of LIN signal, which includes
synchronizing error, ID parity error and checksum error.
