The specific results and lessons learned from one such upgrade of new digital technology into a MATE station are discussed. The issue of compatibility with existing test program sets (TPSs) is usually one of the driving forces for the selection of the new equipment. Analog signal compatibility and pin mapping also must be maintained as much as possible to avoid excessive changes to the test adapters. Analog compatibility issues for digital upgrades include clock ranges, voltage levels, input impedances, and pin drive capabilities. Another major interface to be considered for MATE testers is the CIIL language. Some benefits of technology insertion are considered. Some of the lessons learned that apply to upgrading any test station are in the area of the hidden interfaces and system behaviours that will not be visible from just studying specifications. Some questions are suggested that, if asked, may reduce the problems of upgrading the ATE. In the end, tradeoffs must be made between the cost of TPS incompatibilities and the benefits of newer technology.<<ETX>>","PeriodicalId":273287,"journal":{"name":"Conference Record AUTOTESTCON '92: The IEEE Systems Readiness Technology Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117059219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By designing one common fixture, testing of unloaded and loaded printed wiring boards can be performed in less time and at a reduced cost. The authors discuss the marriage of the two types of test and fixturing philosophies from conception to implementation. Significant time, cost, and maintainability benefits were derived from the union of the printed wiring board tests. The potential benefits, the foreseeable problems, and the course of action in the future at NAWCADI are outlined.<<ETX>>","PeriodicalId":273287,"journal":{"name":"Conference Record AUTOTESTCON '92: The IEEE Systems Readiness Technology Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121797381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated diagnostics is defined as a structured design and management process implemented to achieve the maximum effectiveness of diagnostic capabilities through a concurrent engineering process during weapon system design. The ultimate goal of mechanical systems integrated diagnostics is to achieve condition-based maintenance and prognostics. The focus is on reviewing the trends, requirements, utilization, and shortcomings in the automation of integrated diagnostics with the intent of creating awareness of the current efforts and a perspective for the years ahead.<<ETX>>","PeriodicalId":273287,"journal":{"name":"Conference Record AUTOTESTCON '92: The IEEE Systems Readiness Technology Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124087672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A distributed-resource architecture, modern integration techniques, and a hard-dock scanning solution enable a high-performance VXI-based digital test subsystem to be built. The digital subsystem is described. The development of a hard-docking scanning and fixturing solution for VXI-based automated test equipment systems solves the problems of connecting the digital subsystem to the unit under test, maintains a high-quality ground system, and also provides a means of routing extra power to the digital subsystem.<<ETX>>","PeriodicalId":273287,"journal":{"name":"Conference Record AUTOTESTCON '92: The IEEE Systems Readiness Technology Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115745661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, twisted and shielded cabling is considered that is used to provide protection against electromagnetic interference (EMI), nuclear-induced electromagnetic pulses (ENPs), and high-speed data buses such as MIL-STD-1553B. Also discussed are common failures of shielded and twisted cables and methods of locating the faults. The method discussed in detail is the isolation of these faults by using a highly accurate capacitance comparator along with software to compensate for system and adaptor cable capacitance. Real-world capacitance measurements and the methods used to determine system capacitance tare with grounded and ungrounded systems are discussed. With an accurate system tare, the physical location of the actual defect can be determined.<<ETX>>","PeriodicalId":273287,"journal":{"name":"Conference Record AUTOTESTCON '92: The IEEE Systems Readiness Technology Conference","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121382502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
