Commands Listed in Alphabetical Order
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.

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 search for either the RT (remote terminal response
time), or the IMG (Inter-message Gap). Use the commands SEARCH:
SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:TIMe:QUALifier, SEARCH:
SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:TIMe:LESSLimit,and
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:TIMe:MORELimit
to specify the time parameters.
ERRor specifies to search for a signaling error. (You can specify which type of error
— Parity, Sync, Manchester or Non-contiguous Data — by using the command
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:MIL1553B:ERRTYPE.)
