ID Value
It is valid when trigger condition is “identifier” or “ID or data”. ID value can be set.
When ID parity check is set to “yes”, ID range can set to 00~FF.
When ID parity check is set to “no”, ID range can set to 00~3F.
(3)
Byte Length
It is valid when trigger condition is “data” or “ID or data”. Set the byte length of data to be triggered.
Different byte length has different data range. Byte length range can set to 1
～
8.
(4)
Data
Set the data to be triggered. It is valid when trigger condition is “data” or “ID & data” and the range is 00
～
FFFFFFFFFFFFFFFF.
(5)
Error Type
It is valid when trigger condition is “error”, it can set synchronization, ID parity check and checksum.
a.
Synchronization: synchronizing error
b.
ID parity check: ID parity check error
c.
Checksum: data check and error
(6)
Decoding Setting
Quickly enter the entrance of LIN protocol decoding, refer to reference protocol decoding
7.20 FlexRay Trigger
FlexRay decoding trigger can set trigger condition, trigger coupling, trigger mode and trigger setting.
(1)
Trigger Condition
Set FlexRay trigger condition which includes start frame, indicating bit, identifier, cycle count, header
field, data, ID & data, end of frame and error.
a.
Start frame
：
The oscilloscope generates at the start frame of the transmission.
b.
Indicating bit
：
The waveform generates when the sampled information is in accord with the setting
indicating bit.
c.
Identifier
：
The waveform generates when the sampled data is in accord with the setting identifier.
d.
Cycle number
：
The waveform generates when the sampled cycle number is in accord with the
setting cycle number.
e.
Header field
：
The waveform generates when the header field is in accord with the setting header
field.
f.
Data
：
The waveform generates when FlexRay protocol samples the data is in accord with the user-
defined data. It can help user quickly find the transmission signal of the specific data that
interested.
g.
ID and data
：
The oscilloscope generates when it detects its ID and data is equal to the frame of the
setting value.
h.
End of Frame
：
The oscilloscope generates at the end of frame.
i.
Error
：
The oscilloscope generates at bus error, which includes header CRC error, end of frame CRC
error, empty frame static error, empty frame dynamic error, synchronizing frame error and start
frame error.
