scope:

This standard establishes requirements for digital, command/response, time division multiplexing (Data bus) techniques on aircraft. It encompasses the data bus line and its interlace electronics illustrated on figure 1, and also defies the concept of operation and information flow on the multiplex data bus and the electrical and functional formats to be employed.

When invoked in a specification or statement of work, these requirements shall apply to the multiplex data bus and associated equipment which is developed either alone or as a portion of an aircraft weapon system or subsystem development. The contractor is responsible for invoking all the applicable requirements of this Military Standard on any and all subcontractors he may employ.

A primary goal of the standard is to provide flexibility without creating new hardware and software designs for each new user. This is accomplished by specifying "use of" rather than "required to use" in the functional areas and by specifying the electrical interfaces explicitly so that designs by different manufacturers are electrically interchangeable and functionally compatible.

This validation test plan defines the test requirements for verifying that the design of remote terminals meet the requirements of MIL-STD-1553B, "Digital Time Division Command/Response Multiplex Data Bus." A remote terminal is considered to have failed to meet the above requirements if that remote terminal fails any test or a portion of any test performed according to this test plan. Passing this test plan does not automatically mean that the remote terminal is acceptable for use by the government. The remote terminal must also meet all the requirements of MIL-STD-1553B over all the environmental, EMI, vibration, and application requirements in the subsystem specification.

This general test plan is intended for design verification of remote terminals designed to meet the requirements of MIL-STD-1553B, Notice 2. Appendix A and B provide cross references between this test plan and MIL-STD-1553B. For those remote terminals not required to meet Notice 2, Appendix C and D list the changes in this test plan for MIL-STD-1553B only and MIL-STD-1553B, Notice 1. These requirements shall apply to the terminal under test, when invoked in a specification or statement of work.
