Abstract : An examination of available test equipment for computer assemblies has shown that one basic device exists which is common to all such test equipment. It is the Digital Signal Generator (DSG). The DSG is a programmable pulse generator whose pulse trains are used to generate the digital data for testing all kinds of computer assemblies. For the particular purpose of testing computer memories, the DSG generates variable data patterns and addresses the memory cells sequentially, in a random mode, collectively or selectively. The discriminators then compare responses with the original data on a bit-by-bit, word-by-word basis. The discriminators furnish a go/no-go indication according to prestored threshold levels. The report provides information representative of test equipment from various manufacturers, a listing of military test equipment, and a tabulation according to tester types in order to facilitate the selection of suitable test equipment.
