Frame
Select the frame type to be triggered on.
"Data"
Frame for data transmission.
The identifier format ("ID Type") is also considered.
"Remote"
A 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.
The identifier format ("ID Type") is also considered.
"Data or
Remote"
Triggers on remote frames and on data frames.
The identifier format ("ID Type") is also considered.
"Error"
Triggers on any error frame.
"Overload"
An overload frame is sent by a node that needs a delay between data
and/or remote frames.
Remote command:
TRIGger:A:CAN:FTYPe on page 405
ID Type
Selects the length of the identifier: 11 bit for CAN base frames or 29 bits for CAN
extended frames. Select "Any" if the identifier type is not relevant.
Remote command:
TRIGger:A:CAN:ITYPe on page 405
Error
Identifies various errors in the frame. You can select one or more error types as trigger
condition.
Remote command:
TRIGger:A:CAN:TYPE on page 404
Stuff Bit ← Error
The following frame segments are coded by the bit stuffing method:
●
Start of frame
●
Arbitration field
●
Control field
●
Data field
●
CRC sequence
The transmitter automatically inserts a complementary bit into the bitstream when it
detects five consecutive bits of identical value in the bitstream to be transmitted. A stuff
error occurs when the 6
th
consecutive equal bit level in the mentioned fields is detec-
ted.
Remote command:
TRIGger:A:CAN:BITSterror on page 407
Form ← Error
A form error occurs when a fixed-form bit field contains one or more illegal bits.
Remote command:
TRIGger:A:CAN:FORMerror on page 408
CAN (Option R&S RTB-K3)
