TRIGger:A:BUS
:B<x>:MIL1553B:COMMAND:TRBit
Arguments
QString is a quoted string of up to 5 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:COMMAND:COUNt “01000” sets the bit
pattern for the Word Count/Mode Code field to 01000.
TRIGger:A:BUS:B1:MIL1553B:COMMAND:COUNt? might return “XXXXX”.
TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:PARity
When the MIL-STD-1553 bus trigger condition is set to COMMAND, this command
specifies the Command word parity that is to be used in the trigger.
B<x>
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
and MDO40
00/B/C models or MDO3AERO application module for
MDO3000 models.

TRIGger:A:BUS
:B1:MIL1553B:COMMAND:PARity ZERo
sets the Command
word parity bit to 0.
TRIGger:A:BU
S:B1:MIL1553B:COMMAND:PARity?
might return 0, 1 or X.
TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:SUBADdress
When the MIL-STD-1553 bus trigger condition is set to COMMAND, this command
specifies the 5 bit sub-address that is to be used in the trigger. When the
sub-address value is set to 00000 or 11111 binary, it specifies that the command is
a “Mode Code” command. Any other value specifies that it is a “Word Count”
command.
The default is all X’s (don’t care).
B<x>
NOTE. The sub-address field is u sed to direct data to different functions within the
subsystem for values 1 — 30.
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
and MDO4000/B/C models or MDO3AERO application module for
MDO3000 models.

TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:TRBit
When the MIL-STD-1553 bus trigger condition is set to COMMAND, this command
specifies that the transmit/receive bit (bit 9) is to be used in the trigger. The

elated Commands
TRIGger:A:BUS:B<x>:MIL1553B:CONDition
TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:COUNt
Arguments
RX (logic 0) directs the instrument to trigger on a TX or "transmit" from a remote
terminal .
TX (logic 1) directs the instrument to trigger on an RX or "receive" from a remote
terminal.
X indicates “don’t care".
Examples
TRIGger:A:BUS:B1:MIL1553B:COMMAND:TRBit TX directs the instrument to
trigger on a TX or “transmit” from a remote terminal.
TRIGger:A:BUS:B1:MIL1553B:COMMAND:TRBit TX? might return TX.
TRIGger:A:BUS:B<x>:MIL1553B:CONDition
This command specifies a word type or condition within a MIL-STD-1553 bus
word to trigger on.
B<x>
NOTE. There are three types of MIL-STD-1553 (Aircraft) bus words: Command,
Status, and Data, all sharing a common structure twenty bits in length. The first
three bits are used as a synchronization field. The last bit is the odd parity of the
previous 16 bits.
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
and MDO4000/B/C models or MDO3AERO application module for
MDO3000 models.
