Hardware test systems is a large computer based market. Tested hardware is driven by preset values at its inputs and selected internal points. Output and internal probed values are compared with standard values. A good test system will test the entire board and provide an accurate indication of all failing or marginal components. IEEE has developed a standard for test specification languages, but hardware testing remains an art unique for each new hardware board. (cbb 5/80)
