MIL-STD-1553/ARINC 429 Triggering and Serial Decode
• When the decode format is Label/Data:
• Label (yellow) (8 bits) – displayed in octal.
• Data (white, red if parity error) (23 bits) – displayed in the selected
Base.
The Label bits are displayed in the same order as they are received on the
wire. For the Data, SSM, and SDI bits, the fields are displayed in the
order received; however, the bits within those fields are displayed in
reverse order. In other words, the non- Label fields are displayed in the
ARINC 429 Word Format, while the bits for those fields have the opposite
transfer order on the wire.
ARINC 429 Totalizer
The ARINC 429 totalizer measures the total ARINC 429 words and errors.
The totalizer is always running, counting words and errors, and is
displayed whenever ARINC 429 decode is displayed. The totalizer counts
even when the oscilloscope is stopped (not acquiring data).
Pressing the [Run/Stop] key does not affect the totalizer.
When an overflow condition occurs, the counter displays
OVERFLOW
.
The counters can be reset to zero by pressing the
Reset ARINC 429 Counters
softkey (in the decode Settings menu).
