Most of the other TR IGger:A:BUS:B<x>:MIL1553B commands are impacted
by the setting of this command.
BUS:B<x>:MIL1553B:POLarity
BUS:B<x>:MIL1553B:SOUrce
Arguments
SYNC refers to the 3–bit sync pulse that precedes each word.
COMMAND is one of 3 16–bit word types. It specifies the function that a remote
terminal is to perform.
STATus is one of 3 16–bit word types. Remote terminals respond to valid message
transmissions via status words.
DATA is one of 3 16–bit word types.
TIMe specifies to trigger on either the RT (remote terminal response time), or
the IMG (Inter-message Gap). Use the commands TRIGger:A:BUS:B<x>:
MIL1553B:TIMe:QUALifier, TRIGger:A:BUS:B<x>:MIL1553B:TIMe:
LESSLimit,andTRIGger:A:BUS:B<x>:MIL1553B:TIMe:MORELimit to
specify the time parameters.
ERRor specifies to trigger upon a signaling error. (You can specify which type
of error — Parity, Sync, Manchester or Non-contiguous Data — by using the
TRIGger:A:BUS:B<x>:MIL1553B:ERRTYPE command.)

Examples
:TRIGger:A:BUS:B1:MIL1553B:CONDition STATus sets the word type to
trigger on to
STATus.
:TRIGger:A:BUS:B1:MIL1553B:CONDition? might return DATA.
TRIGger:A:BUS:B<x>:MIL1553B:DATa:PARity
When the MIL-STD-1553 bus trigger condition is set to DATa, this command
specifies the data parity bit to be used in the trigger. Returned values are 0,1,or
X (don’t care).
B<x>
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
and MDO4000/B/C models or MDO3AERO application module for
MDO3000 models.

X
sets the value to X (“don’t care”) which is the default.
ZERO sets the value to 0.
ONE sets the value to 1.
NOCARE sets the value to X (“don’t care”) which is the default.
OFF sets the value to 0.
ON sets the value to 1.
Examples
TRIGger:A:BUS:B1:MIL1553B:DATa:PARity 1 sets the data parity bit to be
used in a MIL-STD-1553 bus trigger to 1.
TRIGger:A:BUS:B1:MIL1553B:DATa:PARity? might return 0, indicating that
the data parity bit to be used in a MIL-STD-1553 bus trigger is set to 0.
TRIGger:A:BUS:B<x>:MIL1553B:DATa:VALue
When the MIL-STD-1553 bus trigger condition is set to DATa, this command
specifies the data binary pattern to be used in the trigger. This is a 16-bit field.
The default is all X’s (don’t care).
B<x>
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
