As avionics busses on military and commercial aircraft become more varied and complex, it becomes even more important that a bus analyzer be used during the design, deployment, and maintenance of avionics systems. Today, aircraft may contain MIL-STD-1553, ARINC 429, CAN, and ARINC 664 (AFDX) busses as part of the overall system. Choosing an analyzer needs to be a part of the overall system design from the earliest part of the project.
