Symbolic ID ← Identifier condition
If a label list with symbolic names was loaded and applied in the bus configuration, you
can select a symbolic name from the list instead of entering the numeric identifier. The
instrument triggers on the identifier of the selected node.
Data condition
The data condition consists of the following settings:
●
Length of the data pattern
●
Comparison
●
Data pattern, see "Bin / Hex pattern" on page 292
Data ← Data condition
Defines the length of the data pattern - the number of bytes in the pattern.
Remote command:
TRIGger:A:CAN:DLC on page 642
Compare ← Data condition
Sets the data comparison condition. If the pattern contains at least one X (do not care),
you can trigger on values equal or not equal to the specified value. If the pattern con-
tains only 0 and 1, you can also trigger on a range greater than or lower than the speci-
fied value.
