The GWTS is mostly commercial-off-the-shelf (COTS) equipment. As such it is subject to component obsolescence. The P/sup 3/I project replaces obsolete COTS, including the system controller with more supportable items. The project goes Further by replacing Compaq/DEC Alpha UNIX with Windows NT12000. This shift requires an en masse re-host of the GWTS software suits Re-host is a challenging process, not without risk, but will more closely align the GWTS design with industry standards. Resources expended now will be more than offset by future savings. The GWTS project is not being conducted in a vacuum. Navy project leaders ensure that CSIST management is continually aware of technical and schedule status, and CSIST engineers will join the team. Raytheon, who is exploring options for new common munitions ATE, monitors upgrade progress, and they have Invited NAWC-WD participation in trade studies for a future Standard Missile test station. The GWTS upgrade team and Raytheon have mutually benefited from this cooperation.","PeriodicalId":334061,"journal":{"name":"2000 IEEE Autotestcon Proceedings.

The intent of our Phase-II work is to provide the Air Force with a \"working tool\" that demonstrates the utility of our architectural approach as well as the utility of AI-ESTATE. The intent of our component based approach to ATS design is to provide a de-coupling of the diagnostic reasoner from the rest of the ATS as well as provide for a true open system at a reduced procurement and maintenance costs. AI-ESTATE is used to provide a standardized interface between the reasoner and the other ATS elements as well as provide standardized information and data model formats. The architecture consists of a COTS Test System (VXI package with LabVIEW), four \"domain\" type components: Diagnostic Engine Component (DEC), Application Executive Component (AEC), Test System Component (TSC) and Model Editing Component (MEC) that plug into our \"Interoperable, Connectivity Enabling Framework\" (ICEF) based on COM/DCOM. The four components and framework are discussed in general terms. The DEC implements AI-ESTATE and is further discussed in derail as are the other components. Also discussed are operational uses, diagnostic development, vendor competition and benefits.","PeriodicalId":334061,"journal":{"name":"2000 IEEE Autotestcon Proceedings.

The MTI AADTS ATE system incorporates an open architecture VXIbus-based and GPIB-based design for test and maintenance of F-15 analog circuit cards. It's an upgrade and refurbishment of an older system, designed to allow old test programs and old test adapters to run on it. All of the instruments in the tester are Commercial-Off-The-Shelf (COTS) units, including the NAI Model 5388 synchro/resolver resource and Model 227 phase-angle voltmeter. NAI's model 5388 is a C size VXI COTS Synchro-Resolver Simulation and Angle Position Measurement card. Interfacing to rugged reliable synchros, the 5388 functionality is based upon highly accurate synchro-to-digital conversion and digital-to-synchro simulation. NAI's model 227 is a wideband message-based phase-angle voltmeter, utilizing the latest DSP technology to provide high performance phase-sensitive, frequency selective voltage measurements. The phase-sensitive measurements of in-phase and quadrature voltage, as well as phase angle, can be made at any frequency from 10 Hz to 100 kHz.","PeriodicalId":334061,"journal":{"name":"2000 IEEE Autotestcon Proceedings.

Generating analog tests by ATLAS or a similar language for the analog part of the Unit Under Test (UUT) and generating digital tests by LASAR for the digital part of the UUT. 2. Generating a single test by ATLAS for both the analog and the digital parts of the UUT. This paper presents another method to generate a single LASAR test that covers both analog and digital components of the OUT. With this method the analog components of the UUT are treated as if they are digital. After the testing strategy is set, behavioral, functional and structural models of the analog chips can be simulated by LASAR. During test generation, treating the whole unit as a digital board will reduce the complexity of the test strategy, the test generation time and consequently the cost of the TPS. The work presented by this paper is based on real-world experience. Real-world examples involved in this paper demonstrate the practicality and the applicability of the method.","PeriodicalId":334061,"journal":{"name":"2000 IEEE Autotestcon Proceedings.
