"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<m>:CAN:ITYPe on page 1495
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.
The trigger point depends on the ID type.
Figure 13-14: Identifier setup for CAN FD
"Frame type"
Data frames and remote frames contain an identifier. Select the frame
type to be triggered on, or select "Any" if the frame type is not rele-
vant.
In CAN FD, only "Data" frames are available.
"ID type"
See: "ID type" on page 568.
"Condition"
Defines the operator to set a specific identifier ("Equal" or "Not
equal") or an identifier range.
"Identifier min"
In binary format, use the following characters: 1; 0; or X (do not care).
To enter the pattern in other formats use the bit pattern editor, see
Chapter 13.1.5, "Bit pattern editor", on page 521.
The length of the bit patterns is restricted to the selected "ID type".
"Identifier max"
The second identifier pattern is required to specify a range with condi-
tions "In range" and "Out of range".
"FD bits"
See: "FD bits" on page 570.
