Don't just re-host-improve

Abstract

Today's ATE/TPS business environment is full of ATE upgrade and replacement projects with an associated TPS re-host. One such project is the development of a replacement for the Re-Entry System Test Set for the Minuteman MK12/12A Re-Entry System. The use of new technology provided several opportunities to go beyond a simple replacement and provide a new tester that solved many existing problems at the field operational sites. One benefit was that downsizing using VXI instrument technology allowed the tester to be transportable which in turn allows the development of new shorter cables since the tester can be moved up to the Re-Entry system components. This will alleviate a safety trip hazard at the field sites. The replacement design also simplifies the test set-up for the operator by elimination of junction boxes and external functional interfaces. Additional implemented improvements include the reduction of functional interfaces, improved MTBF, and inclusion of expansion capability for other current and future Air Force equipment. A significant requirement of this project was to maintain existing operational procedures and processes since they were proven and operators were familiar with them. New technology has improved the operator interface and allowed an upgrade to built-in tailored menus, while maintaining the existing test strategies. Other advanced technology features that were incorporated were the implementation of Built in Test, Built-in Self Test and Diagnostic capabilities. Design for Testability has been implemented for improved diagnostic capability for life-cycle maintenance This paper discusses these and other operational benefits that are being provided by this nuclear certifiable replacement tester.
