The test plan included in the SAE AS4114 standard developed by the Society of Automotive Engineers (SAE) includes two main parts for production testing of bus controllers: electrical testing and protocol testing. This production test plan includes testing requirements to determine that bus controllers meet the digital time division command/response multiplex bus requirements defined in the MIL-STD-1553B standard.
For a very long time, the MIL-STD-1553 standard has been widely used as the defense industry standard for data communication in various applications in aerospace and defense. Commercial avionics for flight equipment on Airbus A-350 aircraft are also adopting this robust bus. Core systems that use it generally have to run for the life of the program and are updated and improved as new technologies become available and adopted. That's why all the time, test methods are also updated to support new designs.
Many new programs still use the MIL-STD-1553 standard as the primary identifier bus and new equipment must support this standard. With the development of test equipment, companies that produce equipment have to perform efficient and effective testing of their equipment in accordance with MIL-STD-1553 standard. Testing is generally conducted in accordance with MIL-STD-4111 test plans, such as industry standard SAE AS4117 to AS1553 for remote terminals and bus control equipment. These standards define all tests that must be performed for devices that comply with the MIL-STD-1553 standard, both during design verification and production testing.
Test documentation defines exactly which tests should be performed, but allows for multiple implementation methods. This gives manufacturers many options for how to design and implement test stations. For example, an integrated system utilizes advanced simulation and analysis software products and the latest hardware with built-in digital scope capabilities, automatically performing all aspects of the test without requiring any engineering development effort.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides production testing services for time division command/response multiplex bus control devices within the scope of SAE AS4114 standard, with its trained and expert staff and advanced technological equipment.
