MOD Sponsored Demonstrations

The UK MOD has sponsored several demonstrations of the use of IEEE 1641. Initially, these were performed to prove the concept and were performed during the development of the standard. Subsequently, these projects were designed to test the use of IEEE 1641 in more advanced program techniques, and to provide input to assist the further development of the standard.

These reports and presentations have been released with the permission of the UK MOD to promote the further understanding and use of IEEE 1641.

This report details a study and demonstration of a test program written in accordance with the developing IEEE 1641 standard. This was performed before the standard was finally completed and approved, so complies with the draft of IEEE project P1641 that was available at the time. This project provided useful information to the P1641 working group prior to the final draft, balloting and approval process.

This study was completed after the IEEE 1641 standard was completed, so was the first full project using the published standard. The objective of this study was "to demonstrate that IEEE Std 1641 is capable of defining and measuring complex Radio Frequency (RF) signals." This project used synthetic instrumentation.

The objective of this project was to produce a test program by applying a test development strategy based on that standard, and compare the results with a traditional approach based on ATLAS. This report provides information on the method adopted to develop the program and its implementation on the test platform and comments upon the use of 1641 compared to traditional methods.

This particular project compared the results from implementing the same test program using two different sets of test equipment, using IEEE 1641 programming techniques. A demonstration of all tests was performed by conventional test techniques to obtain benchmark results to which the results from the subsequent IEEE 1641 program was compared.

Lessons learned

As a result of these projects and other work completed using IEEE 1641, the standard was revised and an updated version was published in 2010. The major changes were to improve the facilities for expressing digital tests. Apart from specific changes and improvements to the standard, it was apparent that more detailed explanation was required to enable users to better understand how to apply the standard to test requirements and how to implement the signals and tests. As a result of these considerations, the User Guide (IEEE Std 1641.1) for the 1641 standard is also in the process of being updated.
