TRIGger:A:BUS
: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.

TRIGger:A:BUS:B<x>:ARINC429A:DATA:VALue
Arguments
LESSthan sets data qualifier to less than.
MOREthan sets the data qualifier to greater 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)

Examples
TRIGger:A:BUS
:B<x>:ARINC429A:DATA:QUALifier LESSthan
sets the
label qualifier to less than.
TRIGger:A:BU
S:B<x>:ARINC429A:DATA:QUALifier?
might return EQUAL
indicating the label qualifier is set to =.
TRIGger:A:BUS:B<x>:ARINC429A:DATA:VALue
This command specifies the low value to be used when triggering on the
ARINC429 bus data field(s). The trigger condition must be set to DATA or
LABELANDDATA (using TRIGger:A:BUS:B<x>:ARINC429A:CONDition).
The defau
lt 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:QUALifier
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 replace 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:VALue
"XXXXXXXXXXXXXXX1000" sets the data field value to
XXXXXXXXXXXXXXX1000.
TRIGger:A:BUS:B<x>:ARINC429A:DATA:VALue? might return
"XXXXXXXXXXXXXXXXXXX".

Commands Listed in Alphabetical Order
TRIGger:A:BU
S:B<x>:ARINC429A:ERRTYPE
This command specifies the error type when triggering on an ARINC429
bus signal. The trigger condition needs to be set to ERROR (using
TRIGger:A:B
US:B<x>:ARINC429A:CONDition). 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
Syntax
TRIGger:A:BUS:B<x>:ARINC429A:ERRTYPE {ANY|GAP|WORD|PARity}
TRIGger:A:BUS:B<x>:ARINC429A:ERRTYPE?
Arguments
ANY sets the error type to match any of the other available error types.
GAP sets the error type to match on gap violations (less than 4 bits idle time
between two packets on the bus).
WORD sets the error type to match on word errors (incorrect number of bits in a
word or bits that violate return to zero transmission).
PARity sets the error type to match on parity errors (parity value results in even
parity count for a word).
Examples
TRIGger:A:BUS:B1:ARINC429A:ERRTYPE ANY sets the error type to match
any of the other available error types.
TRIGger:A:BUS:B1:ARINC429A:ERRTYPE? might return PARity.
TRIGger:A:BUS:B<x>:ARINC429A:LABel:HIVALue
When the trigger condition is set to LABel, and the qualifier is set
to either INrange or OUTrange, this command specifies the upper
value of the range for a trigger on the label field. (Use the command
TRIGger:A:BUS:B<x>:ARINC429A:LABel: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.
