Effective automated test equipment is built upon the idea of abstracted layers to provide a flexible, robust, and comprehensive test environment. The layers must be plentiful and each one offer abstracted abilities of lower layers. In addition, if a layer is absent, the lack of that layer must not disrupt the ability to use lower ones; a layer must be independent of any higher (observer) layers. This...
Today's fast paced world of ever changing Commercial-Of-The-Shelf (COTS) hardware and software architectures creates a quandary in that the end-user must be cognizant of these effects on their own legacy based system when embracing a new design. The advantages of moving to a newer and sleeker system surely outweigh the complexities of attempting to maintain an older system especially when obsolescence...
Compact and robust automated testing and control solution for the F-15 Jet Fuel Starter and Central Gearbox assemblies utilizing the NI-cRIO family of instrumentation. System design and implementation being performed on a non-interference basis with the customer's current production schedule.
This paper will describe the Integrated Process Team developed between the US Air Force VDATS program team and the Lockheed Martin LM-STAR team. Independently, both groups have designed a common ATS solution to reverse the excessive life cycle sustainment costs associated with the proliferation of unique test systems throughout their customer base. Both groups recognized the similarities in instrumentation,...
Reconfigured Parallel Test Grid (RPTG) technology advanced a novel theory to improve test and ATE using efficiency. In order to analyze the function and efficiency of RPTG, it is important to simulate the RPTG environment authentically. Based on parallel and reconfigured characteristic of RPTG, HLA-based layered analytic simulation architecture was put forward. This solution can exploit the parallelism...
This paper examines the testing and production processes used on the CASS Phase II TPS Offload Program. The CASS Phase II TPS Offload program is a US Navy acquisition to replace legacy ATE Systems using CASS (Consolidated Automated Support System) Test Stations. This provides the Navy intermediate maintenance activities an effective tool for restoring “Ready For Issue” (RFI) status for over 450 aircraft...
How to identify when a static pattern digital test program should be re-hosted as a dynamic pattern set on the state-of-the-art ATE is complicated. However, there are critical issues that should be evaluated when making this decision. Issues include chip models, timing parameters, drive strength, logic levels, circuit complexity, I/O pins, automated diagnostics, portability, reuse, speed, optimal...
The operating models that most organizations have adopted over the past several decades are changing rapidly, and Lockheed Martin has worked with our customers to adapt to the new environment. Automated Test Equipment (ATE) and DoD partnering have played an important role in this adaptation. Insertion of new technologies and commercial best practices has demonstrable benefit through the entire supply...
A new revision of IEEE Std 1641 has been completed and should be available before the end of the year. This standard, which provides a method of accurately defining signals and tests, has been further developed with many new improvements. The standard provides for libraries of pre-defined signals which may be re-used within a technology or project. There have been many examples of stimulus signals,...
As the complexity and functionality of electronic equipment increases over time, testing of modern day electronics has brought about the need for more complex stimulus and measurement capabilities. New methodologies such as Virtual and Synthetic Instrumentation have emerged to provide a more flexible ATE that can be re-configured to support a variety of technologies required by the modern day unit...
