Timing: Min gap, Max gap ← Error Conditions
Defines the idle time between two words, which is needed for word synchronization.
The beginning of the first bit after the gap marks the start of a new word.
You can define a minimum idle time "Min gap", and/or a maximum time "Max gap". The
standard defines a minimum of 4-bit times to separate two subsequent words.
Timing settings are relevant for protocol configuration and error trigger.
If "Min gap" and/or "Max gap" are enabled, the instrument detects the specified gaps
during decoding. If the trigger type "Error condition" is selected in addition, the instru-
ment triggers when the gap is shorter or longer than the specified gaps, respectively.

3. Tap the "Source" button and select the "Serial bus" trigger source.
4. Select the serial bus that is set to ARINC 429.
5. Select the "Trigger type".
6. For more complex trigger types, enter the data pattern conditions.
For details, see Chapter 13.8.3.1, "ARINC 429 trigger settings", on page 619.
13.8.4 ARINC 429 label list
Label lists are protocol-specific. An ARINC 429 label file contains two values for each
identifier:
●
"Arinc Label": the ARINC 429 label value, that identifies the data type and the
parameters associated with it. The usual data format is octal.
●
"Symbolic label": symbolic name of the label, specifying its function.
Example: ARINC 429 PTT file
# ----------------------------------------------------------------------------
@FILE_VERSION = 1.0
@PROTOCOL_NAME = arinc429
