The instrument performs real-time spectrum analysis in the DC-to-10 MHz range at 5000 spectrums per second. Its architecture is based on the VMEbus and is partly adapted for high-speed pipeline processing. The keyboard and color graphic displays suit basic spectrum analysis, as well as advanced analysis of amplitude vs. both frequency and time. The instrument provides a DSP (digital signal processing) programming environment when an RS232 terminal is attached. With addition of an RF spectrum analyzer, downconverter, and software, real-time analysis is extended to 21 GHz and beyond. Postprocessable spectral output makes the instrument suitable for use in a larger signal analysis or test system. This digital spectrum analyzer, which has 17 boards on the bus, is representative of an emerging class of filled-enclosure instruments.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The VXIbus architecture allows significant reduction in the footprint of the traditional rack-and-stack ATE systems. In addition, the VXIbus offers significant advantages in the area of addressing instrument functions, message-passing, time synchronization, power-on initialization and diagnostics, and system throughput. The VXIbus combines multivendor computer and instrumentation functions into a common mainframe and supports interchangeability and interoperability.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

{"title":"Transport of CAE data: a discourse analysis view","authors":"A. Lowenstein, D. Hall, S. Schlosser, G. Winter","doi":"10.1109/AUTEST.1989.81103","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81103","url":null,"abstract":"The theorems and terminology of discourse analysis are used to illuminate important issues and clarify areas of controversy associated with the transport of electronic data. This view of data transport reveals that an ATE (automatic test equipment) of CAE (computer-aided engineering) database is never independent of the tools or environment which create and use the data. This lack of independence is shown to compromise the fundamental principles of the traditional implementations of database-centered and three-schema architectures. A consequence is the 'premature geriatric diseases' which commonly degrade such approaches. Solutions based on the lessons learned from discourse analysis are proposed. The importance of performing a deterministic well-defined mapping, i.e. isomorphic mapping, is explained. The use of orthogonal systems, when possible, guarantees that such a mapping can be performed. Netlists are shown to have special attributes which facilitate mapping. An approach to the creation of standards is proposed that constrains the use of nonorthogonal standards, such as computer languages, to express data. Thereby, the transport becomes, or at least approaches, a deterministic well-defined mapping.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Timmons","doi":"10.1109/AUTEST.1989.81095","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81095","url":null,"abstract":"The two-level maintenance (TLM) concept is being advocated as a means of increasing support capability and reducing the total cost of system maintenance. Traditionally, the Air Force has used a three level maintenance concept, with a heavy emphasis on base level, in-shop repair. In the 1970s and 1980s, this approach to maintenance and the expanding technology of automated test systems resulted in sophisticated and powerful, but costly and resource-consuming automated test systems being developed and deployed worldwide. With continuing advances in reliability, and emphasis on supportable designs, it is apparent that, under certain combinations of resource costs, item reliability, and usage rates, two levels of maintenance provide more support at less cost and consume less resources than does three-level maintenance. The objective of TLM is to eliminate, when feasible, the base-level repair shop from the maintenance structure. The authors explore the rationale behind and the methods of identifying the optimum level of repair, and explain why it is necessary to analyze the requirements before assigning a particular maintenance task to a certain level of maintenance.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The author argues that this inherent potential ATE system capability has not been used effectively. It has been treated as an afterthought and implemented by the most prosaic of methods. The results of this inadequate and inappropriate treatment of ATE self-test has been stagnation in improved MTBF of new ATE systems and regression in MTTR. The maintenance and training problems for new and modern ATE have been exacerbated rather than reduced. The author contends that this situation is a result of neglect and apathy on the part of ATE systems developers who have failed to be innovative or attentive to modern system techniques in the design of self-test for their ATE. The author proposes a five-phase ATE self-test approach that he hopes can resolve the above-mentioned problems. The phases are: pre-ATE planning; ATE planning; self-test implementation; self-test maturity and evaluation; and self-test feedback/archiving.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

His analysis shows that using the VHSIC Phase 2 interface buses (PI bus, TM-bus, and ETM-bus) and maximizing the use of system/module/IC built-in-test, a 25-MHz tester can satisfy depot test requirements. In addition, bus interface circuits designed to emulate the internal/external event-driven VHSIC bus protocols at operational speeds facilitate this concept.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The authors describe how the model-based reasoning system is used to generate automatically diagnostic trees that can have variable degrees of branching, from binary to ternary (nodes with high, OK, and low branches) to n-ary trees. With branching degrees at or above ternary, these trees are capable of fault isolating within loops and can in fact isolate multiple faults. The trees can utilize much of the information content in quantitative measurements to make efficient and accurate diagnoses not possible with the binary tree. Both efficiency and accuracy of diagnosis increase with the branching factor of the tree. Automated tree generation provides effective automated diagnostics to applications requiring low-cost hardware and fast response time.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The system integrates multiple maintenance information sources into a single easy-to-use information system. Integrated diagnostics relative to ATE has focused on the improved operator interfaces, embedded training, maintenance aiding, information handling and presentation, and documentation. The author presents a system which integrates these functions into a DMI system. The primary application is the presentation of video, graphic, schematic, and instructional text and data in the form of interactive scripts which are displayed to the ATE operator in a PC environment. These scripts visually demonstrate operator support functions during testing including unit-under-test hookup, alignment and adjustment procedures, probing steps, and repair actions. Embedded training in the use of the system, online help, DMI diagnostics, heuristic data collection and retrieval, and electronic network analysis aides are provided using an integrated expert system.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The analyses compare the costs associated with a strict two-level maintenance concept with the resulting costs of other maintenance alternatives (e.g. three- and four-level, with and without screening). The authors identify the sensitivity of the resulting cost to such factors as inaccurate built-in test (BIT); TMDE (test measurement and diagnostic equipment) costs, including test program sets; provisioning levels and supply support measures, including number and placement of test equipment and maintenance personnel; and the impact of repair vs. discard. The cost of each policy is assessed not only in terms of dollars, but also in terms of operational availability and system readiness.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.
