Electronic modules that can be faulted by remotely controlled switching are potentially valuable aids in the training of operating and maintenance personnel in the recognition and diagnosis of- failures and performance degradation in complex electronic systems. Oas, inc., proposes an investigation of low-level microwave and supersonic switching devices that might be attached to an electronic module to be faulted by an instructor operating a remote microwave or supersonic transmitter. Alternatively, a miniature timer that allows arbitrary switch closing times to be programmed within it will be evaluated and compared with the remote switching devices. This phase i effort will involve a search for suitable components, miniaturized designs of chosen components, an evaluation of expected performance, and testing of components whose performance cannot be predicted.
