Testing & Debugging Avionics Systems that Use ARINC 429 or MIL-STD-1553 Data Busses

资料介绍
The data busses in aircraft and spacecraft require very high quality in transmission and reception since proper communication of commands and data are crucial to operation. The ARINC 429 standard used predominately in commercial aircraft and the MIL-STD-1553 bus used in military avionics and space vehicles (military and commercial) have some common characteristics as well as important differences. This paper will give useful examples of how to view, test and troubleshoot these busses using digital oscilloscopes.

Physical Characteristics
January 11, 2012
As with many serial data systems, both ARINC 429 and MIL-STD-1553
are differential busses. ARINC 429 is the simpler and less costly of the
Summary two. The physical connection is via twisted pair wires with balanced
differential signals. It uses a self clocking, self synchronizing data bus.
The data busses in aircraft
MIL-STD-1553 uses dual redundant balanced differential pairs. The peak
