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.

Arguments
0
1
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

TRIGger:A:BUS
:B<x>:MIL1553B:CONDition
TRIGger:A:BUS:B<x>:MIL1553B:DATa:PARity
Arguments
QString is a quoted string of up to 16 characters, where the allowable characters
are 0, 1, and X. The bits specified in the quoted string replace the least significant
bits, leaving any unspecified upper bits unchanged.
Examples
TRIGger:A:BUS:B1:MIL1553B:DATa:VALue “01000” sets the data binary
pattern to be used in a MIL-STD-155
3 bus trigger to 01000.
TRIGger:A:BUS:B1:MIL1553B:DATa:VALue? might return
XXXXXXXXXXX01000.
TRIGger:A:BUS:B<x>:MIL1553B:ERRTYPE
When the MIL-STD-1553 bus trigger condition is set to ERRor, this command
specifies the signaling error type to be used in the trigger: Parity, Sync,
Manchester or Data.
B<x>
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
and MDO4000/B/C models or MDO3AERO application module for

Related Commands
TRIGger:A:BUS:B<x>:MIL1553B:CONDition
Arguments
PARity — an incorrect parity setting.
SYNc — the high to low, or low to high transition doesn’t happen in the middle
of the sync time as it should.
MANCHester — no transition in a bit time.
DATA — a non-contiguous data error.
