H<x>: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.
Examples
SEARCH:SEARCH1:TRIGger:A:BUS:B1:MIL1553B:COMMAND:COUNt
“01000”
sets the bit pattern for the Word Count/Mode Code field to 01000.
SEARCH:SEARCH1:TRIGger:A:BUS:B1:MIL1553B:COMMAND:COUNt? might
return “XXXXX”.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:PARity
When the MIL-STD-1553 bus search condition is set to COMMAND, this command
specifies the Command word parity that is to be used in the search.
SEARCH<x>
is the search number, which is always 1, and 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.

OFF sets the val
ue to 0.
ON sets the value to 1.
Examples
SEARCH:SEARCH1:TRIGger:A:BUS:B1:MIL1553B:COMMAND:PARity ZERo
sets the Command word parity bit to 0.
SEARCH:SEARCH1:TRIGger:A:BUS:B1:MIL1553B:COMMAND:PARity?
might return 0, 1 or X.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:SUBADdress
When the MIL-STD-1553 bus search condition is set to COMMAND, this command
specifies the 5 bit sub-address that is to be used in the search. 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).
SEARCH<x> is the search number,
whichisalways1,and
B<x>
NOTE. The sub-address field is used 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.

SUBADdress “01000”
sets the sub-address to be used in the search to 01000.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:COMMAND:TRBit
When the MIL-STD-1553 bus search condition is set to COMMAND, this command
specifies that the transmit/receive bit (bit 9) is to be used in the search. The
transmit/receive bit defines the direction of information flow, and is always from
the point of view of the remote terminal.
SEARCH<x> is the search number, which
is always 1, and
B<x>
Conditions
This command requires a DPO4AERO application module for DPO/MSO4000B
