Agilent InfiniiVision 4000 X-Series Oscilloscopes User's Guide 451
• Data — the 11 bits after the RTA for Command/Status words, or the 16
bits of a Data word.
• Errors — "Sync", "Parity", or "Manchester" errors as appropriate. The
background color is red to indicate an error.
Aliased data is highlighted in pink. When this happens, decrease the
horizontal time/div setting and run again.
Searching for MIL-STD-1553 Data in the Lister
The oscilloscope's search capability lets you search for (and mark) certain
types of MIL- STD- 1553 data in the Lister. You can use the
[Navigate]
key
and controls to navigate through the marked rows.
1 With MIL- STD- 1553 selected as the serial decode mode, press [Search] .
2 In the Search Menu, press the Search 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 Search ; then, select from these options:
• Data Word Start — finds the start of a Data word (at the end of a valid
Data Sync pulse).
•
Command/Status Word Start
— finds the start of Command/Status word
(at the end of a valid C/S Sync pulse).
• Remote Terminal Address — finds the Command/Status word whose RTA
matches the specified value. The value is specified in hex.
When this option is selected, the
RTA
softkey becomes available and
lets you select the hex Remote Terminal Address value to find.
• Remote Terminal A 11 Bits — finds the RTA and the remaining 11
bits that 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).
• Parity Error — finds (odd) parity bits that are incorrect for the data in
the word.
