<p>A number of standardized microprocessors (4a-4d) are used as building blocks for gaining access and control to other standardized functional resource circuit units (6-16). One of the microprocessors (4a-4d) is selected by a main processing unit (2) to capture the different functional resource circuit units (6-16) 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 (5) 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.</p> |
