These circuits protect sensitive transistor and resistor components from electrical surges. Data were collected for 110 waveforms for a combination of good circuits and the most frequently encountered failure modes, including shorted diodes, open diodes and bad amplifiers. The data were then used to train a neural network pattern recognition system to see if neural network technology could correctly identify good versus bad protection circuits. When trained using all of the diodes, the neural network was able to identify correctly all of the circuits and associated failure models. To validate the neural network model, a subset of 59 samples was randomly selected for training of the neural network, and the remaining 51 samples were used for testing. In both instances, the network did an excellent job (100%) of identifying failure.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

He notes that newly defined mission requirements place increased emphasis on equipment downsizing and improved transportability. Over the past several years, technology has produced products that promise powerful solutions to testing and significantly reduce the size and footprint of ATE. The innovative implementation of this technology forms the basis by which MATE can be realistically applied to the downsized test environment. An example of a MATE compliant downsized tester architecture is presented.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

This test system is intended to test readouts, sensor chip assemblies, modules, and complete FPAs. The test station was developed in response to existing and anticipated project requirements that exceed the performance capabilities of existing test stations. A new generation test station will require enhanced performance, such as the ability to accommodate increased data rates, generate lower noise drive electronics, and provide improved diagnostic capability. The goal was to develop a test vehicle that was configurable enough to accommodate the projected FPA test requirements for the next several years, thereby eliminating the need for a new design test station for each individual program. Two types of programs were considered when specifying the new test station: development programs where a substantial amount of diagnostic and analysis capability is required, and production programs where test time and ease of use are critical. If a flexible test station design could be achieved, the nonrecurring costs to implement a new program could be greatly reduced, both in test equipment design and in training test personnel.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Two examples of downsized VXIbus systems are evaluated. One is a C-size system with DC to microwave capability for factory floor or transportable ATE (automatic test equipment) applications. The second is a B-size system that is a lower performance equivalent of the C-size system with the microwave functionality removed; it is applicable for transportable and portable ATE. Actual examples of reduced-size test equipment ranging from battery operated testers to rack mounted, factory-based test systems are shown and evaluated. It is concluded that the VXIbus can deliver substantial reductions in test system size for factory, transportable, and portable ATE. Size reduction averages about 3 to 1 over equivalent HP-IB rack and stack instruments.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The heart of the system is an embedded VXIbus processor for controlling the test system and implementing virtual instruments. The software bus concepts of its multitasking operating system make it possible to create or delete software packages dynamically and to control the measuring resources. The system has rigorous control over dynamic resource allocation and is garbage-collection-free.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Measuring system performance characteristics of infrared systems (MRT, MTF, NETD) using automatic test equipment 利用自动测试设备测量红外系统(MRT、MTF、NETD)的系统性能特性

Gibson","doi":"10.1109/AUTEST.1989.81127","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81127","url":null,"abstract":"A project is described whose goal is to develop and test image signal processing algorithms and techniques that allow automation of MRT (minimum resolvable temperature) testing. The basis of the automated test system is the premise that the system MTF (modulation transfer function) is a product of the MTFs of each subsystem component. The MTF of the lens and detector are the major factors affecting system MTF. Therefore, for a given forward-looking infrared system, if the detector and lens system remain constant, the system MTF should be constant. Thus, the results of an automated measurement of the system MTF will remain constant relative to the MTF measurement obtained from human observers. If the constant is proven valid, then it can be reasoned that for all subsequent units of identical design, a constant can be applied to allow verification of system critical parameters to be conducted using automated methods of testing with the same or nearly the same confidence levels compared to the older manual methods. This set of data would be far more repeatable and correlate closer to actual field results. The use of a qualified, quantifiable, and repeatable constant results in a more realistic assessment of actual performance and the removal of human subjectivity from the equation.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

These configurations offer higher performance for repeatability of test, timing accuracy, and system throughput. A discussion of extended start/stop protocol and SYNC100 triggering illustrates how tight timing synchronization between instrument modules results in a high degree of measurement repeatability. In addition, it is noted that dramatic improvements in throughput can be achieved utilizing hardware sequencing where VXI system resources are used to minimize time-consuming intervention by the system controller. A test system comprising a digitizer, an arbitrary waveform generator, and a scanner is discussed, with emphasis on the implementation of extended start/stop protocol and hardware sequencing to potential system applications. Attention is given to the instrument features differentiating these products from their rack and stack counterparts.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.
