AUTOMATED TEST APPARATUS FOR USE WITH MULTIPLE EQUIPMENT

摘要

A number of standardized microprocessors are used as building blocks for gaining access and control to other standardized functional resource circuit units. One of the microprocessors is selected by a main processing unit to capture the different functional resource circuit units needed to perform functions of a discrete test instrument. To instruct the different resource circuit units to perform the needed functions, a program is downloaded from a mass memory by the microprocessor. After having performed the necessary functions, the microprocessor releases the different functional resource circuit units, which - along with the microprocessor - would return to idle and await the next selection.
