Title: Application of Microprocessors for Miniaturized TMDE.
Abstract: Abstract : The goal of this project was to establish the feasibility of developing miniaturized, automatic contact and repair test equipment (CARTE) using a microprocessor as the control and computational element. By changing the firmware via either cassette tapes or plug-in ROM's, the CARTE could be used by contact teams in the field to diagnose and repair a variety of operational equipment. The use of third generation automatic test equipment (ATE) techniques was to be emphasized in order to minimize the amount of hardware required. A laboratory demonstration system was assembled to provide basic stimulus, measurement, and testing capabilities based on a microprocessor and using third generation ATE techniques. The system hardware consisted of the microprocessor and its memory and I/O bus, a digitally synthesized software controlled stimulus generator, a software controlled amplitude sampling unit, a frequency counter under remote control via an IEEE bus, and various peripherals. The peripherals included two cassette transports for data storage, a special function keyboard, a CRT terminal, and a serial printer for hardcopy of the CRT screen contents. The special hardware designs of the digitally synthesized stimulus generator and amplitude sampling units permit the microprocessor software to control both the setup and operation of both the stimulus and measurement functions of the laboratory model.
