MIL-STD 1553 Triggering
To set up the oscilloscope to capture MIL- STD 1553 signals, see “Setup for
MIL- STD 1553 Signals” on page 325.
To set up a MIL- STD 1553 trigger:
1 Press [Trigger]; then, select the MIL-STD-1553 trigger type.
2 In the Trigger Menu, press the Trigger softkey on the right side; then,
select from these options:
• Data Word Start – triggers on the start of a Data word (at the end of a
valid Data Sync pulse).
• Data Word Stop – triggers on the end of a Data word.
• Command/Status Word Start – triggers on the start of Command/Status
word (at the end of a valid C/S Sync pulse).
• Command/Status Word Stop – triggers on the end of a Command/Status
word.
• Remote Terminal Address – triggers if the RTA of the Command/Status
word matches the specified value.
When this option is selected, the RTA softkey appears and lets you
select the hex Remote Terminal Address value to trigger on. If you
select 0xXX (don’t cares), the oscilloscope will trigger on any RTA.
• Remote Terminal Address + 11 Bits – triggers if the RTA and the
remaining 11 bits match the specified criteria.
When this option is selected, the RTA + Bits softkey appears and
opens the MIL- STD- 1553 RTA + 11 Bits Menu. In this menu:
• The RTA softkey lets you select the hex Remote Terminal Address
value.
• The Bit Time softkey lets you select the bit time position.
• The 01X softkey lets you set the bit time position value as a 1, 0,
or X (don't care).
