"Error condition"
Identifies various errors in the frame. You can select one or more
error types as the trigger condition.
Remote command:
TRIGger:CAN:TYPE on page 461
Frame type
CAN has several frame types which can be used as trigger condition.
For data and remote frames, the identifier format has to be set with ID type.
"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 an overload frame.
The instrument triggers seven bit-periods after the end of the over-
load flag that is marked by a dominant-recessive edge.
The ID type is irrelevant for overload frames.
"Data"
The data frame is the only frame for actual data transmission.
"Remote"
Remote frames are only available in the CAN protocol.
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.
"Data or
Remote"
Data frames or remote frames initiate the transmission of data by
another node. The frame format is the same as of data frames.
Remote command:
TRIGger:CAN:FTYPe on page 459
ID type
Selects the length of the identifier:
"11 bit"
Identifier length of the CAN base frame format. The instrument trig-
gers on the sample point of the IDE bit (identifier extension flag).
"29 bit"
Identifier length of the CAN extended frame format. The instrument
triggers on the sample point of the RTR bit.
"Any"
The ID type and ID pattern are not relevant for the trigger condition.
If the trigger type is "Identifier", the instrument triggers on any identi-
fier in the specified frame type.
If the trigger type is "Identifier + Data", set the "ID type" to "Any" if you
want to trigger only on data.
Remote command:
TRIGger:CAN:ITYPe on page 460
Identifier Pattern
Specifies the identifier pattern to be found, in binary or hex format. Enter the pattern in
MSB first bit order.
