MIL-STD-1553 Triggering
To set up the oscilloscope to capture a MIL-STD-1553 signal, see “Setup for
MIL-STD-1553 Signals" on page 481.
To set up a MIL-STD-1553 trigger:
1 Press [Trigger].
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob to
select the serial slot (Serial 1 or Serial 2) on which the MIL-STD-1553 signal is
being decoded.
3 Press the Trigger softkey; then, turn the Entry knob to select the trigger
condition:
• 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 becomes available 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, these softkeys become available:
• The RTA softkey lets you select the hex Remote Terminal Address value.
• The Bit Time softkey lets you select the bit time position.
• The 0 1 X softkey lets you set the bit time position value as a 1, 0, or X
(don't care).
