The capability of a test system is further enhanced by the implementation of EADS North America Defense Test & Services' isolATE™ interface. The isolATE™ interface is designed to maximize the supportability and maintainability of our test systems by allowing instrumentation to be upgraded or replaced without impacting Test Program Software. Although most functional automatic test systems use only one computer system, the flexibility of the isolATE™ approach allows it to be implemented on single or multiple computer systems while maintaining the same efficient and streamlined structure. The isolATE™ approach provides a modular software interface which segregates code functionality. This allows Test Program Software to operate based solely on data presented by the isolATE™ interface, regardless of the specific instrument that is providing the data.
