Setup for ARINC 429 Signals
Setup consists of first connecting the oscilloscope to a ARINC 429 signal
using a differential active probe (the Agilent N2791A is recommended),
then using the Signals Menu to specify the signal source, the high and low
trigger threshold voltage levels, the signal speed, and the signal type.
To set up the oscilloscope to capture ARINC 429 signals:
1 Press [Label] to turn on labels.
2 Press [Serial].
3 Press the Serial softkey, turn the Entry knob to select the desired slot
(Serial 1 or Serial 2), and press the softkey again to enable decode.
4 Press the Mode softkey; then, select ARINC 429 decode mode.
5 Press the Signals softkey to open the ARINC 429 Signals Menu.
6 Press Source; then, select the channel for the ARINC 429 signal.
The label for the ARINC 429 source channel is automatically set.
7 Press the Speed softkey and specify the speed of the ARINC 429 signal:
• High — 100 kb/s.
• Low — 12.5 kb/s.
8 Press the Signal Type softkey and specify the signal type of the ARINC
429 signal:
• Line A (non-inverted).
• Line B (inverted).
• Differential (A-B).
9 Press the Auto Setup softkey to automatically set these options for
decoding and triggering on ARINC 429 signals:
• High Trigger Threshold: 3.0 V.
