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
Data ← Data condition
Defines the length of the data pattern - the number of bytes in the pattern.
Remote command:
TRIGger:A:LIN:DLENgth on page 658
Compare ← Data condition
Sets the comparison condition: If the pattern contains at least one X (don't care), you
can trigger on values equal or not equal to the specified value. If the pattern contains
only 0 and 1, you can also trigger on a range greater than or lower than the specified
value.
Remote command:
TRIGger:A:LIN:DCONdition on page 658
Bin / Hex ← Data condition
Specifies the data pattern to be triggered. To set an individual binary bit or hexadecimal
nibble (half byte), tap it and enter it via the on-screen keypad. Make sure to specify
complete bytes.
"Bin"
String containing the binary pattern with a maximum of 64 bits. Char-
acters 0, 1 and X are allowed.
"Hex"
String containing the hexadecimal pattern with a maximum of 8 bytes.
Characters 0 to F and X are allowed.
Remote command:
TRIGger:A:LIN:DATA on page 657

See Chapter 13.1.2, "Displaying decode results", on page 253.
