"Identifier +
Data"
Sets the trigger to a combination of identifier and data condition. The
instrument triggers at the end of the last byte of the specified data pat-
tern.
The identifier conditions are the same as for the "Identifier" trigger type,
see "Identifier setup: Condition, Identifier min, Identifier
max" on page 290. Data conditions are set with "Data setup: DLC,
Transfer, Condition, Data min, Data max" on page 291.
"Error condi-
tion"
Identifies various errors in the frame, see "Error conditions: CRC, Bit
stuffing, Form, Ack" on page 292.
SCPI command:
TRIGger<m>:CAN:TYPE on page 688
Frame type
CAN has four frame types which can be used as trigger condition.
For data and remote frames, the identifier format has to be set with ID type.
"Data"
The data frame is the only frame for actual data transmission.
"Remote"
The remote frame initiates the transmission of data by another node.
The frame format is the same as of data frames but without the data
field.
"Error"
When a node recognizes an error, it cancels transmission by sending
an error frame.
The instrument triggers seven bit periods after the end of the error flag
that is marked by a dominant-recessive edge.
The ID type is irrelevant for error frames.
"Overload"
When a node needs a delay between data and/or remote frames, it
sends and overload frame.
The instrument triggers seven bit periods after the end of the overload
flag that is marked by a dominant-recessive edge.
The ID type is irrelevant for overload frames.
SCPI command:
TRIGger<m>:CAN:FTYPe on page 688
ID type
Selects the format of data and remote frames.
"11 bit"
Standard format. The instrument triggers on the sample point of the IDE
bit.
"29 bit"
Extended format. The instrument triggers on the sample point of the
RTR bit.
"Any"
The ID type is not relevant. If the trigger type is "Identifier + Data", set
the "ID type" to "Any" if you want to trigger only on data.
SCPI command:
TRIGger<m>:CAN:ITYPe on page 689
Identifier setup: Condition, Identifier min, Identifier max
The identifier setup consists mainly of the condition and one or two identifier patterns.
Additionally, ID type and frame type may qualify the identifier.
