MIL1553B specifies the MIL-STD-1553 bus.
TRIGger:A:BUS:B<x>:ARINC429A:CONDition
This command sets the condition (word start, label, matching data, word end, or
error) to b
e used to trigger on CAN bus data. B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

Arguments
STARt enables triggering on the first bit of a word.
END enables triggering on the 32nd bit of a word.
LABel enables trigger on a matching label.
DATA enables triggering on matching packet data field(s).

TRIGger:A:BUS:B<x>:ARINC429A:DATA:HIVALue
When the trigger condition is set to DATA or LABELANDDATA, and the
qualifier is set to either INrange or OUTrange, this command specifies the
upper value of the range for a trigger on the data field. (Use the command
TRIGger:
A:BUS:B<x>:ARINC429A:DATA:VALue to specify the lower value of
the range). The default is all X's (don't care). B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

TRIGger:A:BUS:B<x>:ARINC429A:DATA:VALue
Arguments
QString is a quoted string of 19, 21, or 23 bits. The allowable characters are0,
1, and X. The bits specified in the quoted string repla
ce the least significant bits,
leaving any unspecified upper bits unchanged.
NOTE. The size of the QString is dependent on the data field format selected using
BUS:B<x>:ARINC429A:DATA:FORMAT. Also, the store d QString is reset to its
default value whenever the data field format is changed.
Examples
TRIGger:
A:BUS:B<x>:ARINC429A:DATA:HIVALue
"XXXXXXXXXXXXXXX1000" sets the upper limit of the range to
XXXXXXXXXXXXXXX1000.

:B<x>:ARINC429A:DATA:HIVALue?
might return
"XXXXXXXXXXXXXXXXXXX".
TRIGger:A:BUS:B<x>:ARINC429A:DATA:QUALifier
This command specifies the qualifier to be used when triggering on the ARINC429
data field(s). The trigger condition must be set to DATA or LABELANDDATA.
The default qualifier is “Equal to”. B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

Arguments
LESSthan sets data qualifier to less than.

EQual sets the data qualifier to equal.
UNEQual sets the data qualifier to not equal.
LESSEQual sets the data qualifier to less than or equal.
MOREEQual sets the data qualifier to greater than or equal.
INrange sets the data qualifier to in range.
OUTrange sets the data qualifier to out of range.
NOTE. Thetriggerqualifier only applies to the bits defined as the data field via the
bus data field format specifier (using BUS:B<x>:ARINC429A:DATA:FORMAT)
