ABSTRACT:
A maintenance training system capable of precisely simulating both the inner and the outward functions of original electronic equipment is realized by utilizing a programmable waveform generator, a microcomputer and interfacing input/output circuits in a modular design that can be adapted to use with virtually any desired electronic system maintenance trainer. The system provides genuine waveform generation and display in a real time maintenance trainer with positive input/output control through line replacable unit read/write modules. The programmable waveform generator develops analog waveforms from digital control and picture data received from the micro-computer. The analog outputs of the programmable waveform generator drive the maintenance trainer's external meters, displays and oscilloscope and can be programmed to simulate point by point circuit tracing of the original electronic equipment.
