"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 "Iden Data", set the "ID type" to "Any" if you
want to trigger only on data.
Remote command:
TRIGger<m>:CAN:ITYPe
on page 1802
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.
"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 589.
"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 13.1.7, "Bit pattern editor" , on page 493.
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 590.

FD bits
For standard settings " CAN FD" and "Any", you can trigger on CAN FD-specific bits.
"FDF" The bit determines whether a frame is CAN or CAN-FD. It corre-
sponds to the EDL bit (extended data length), which only exists in
CAN FD format. If you do not know if the signal is CAN or CAN FD,
you can use this bit to identify the format: FDF = 1 is CAN FD, and
FDF = 0 is CAN. Set "X" if the format is not relevant.
"BRS" is the bit rate switch bit. Value 1 means that the bit rate switches from
the "Arbitration rate" to the faster "Data rate".
"ESI" is the error state indicator. Set "X" if the bit is not relevant.
