Abstract
The present invention employs random electrostatic discharges to stress test electrical machinery, particularly digital computer systems running repetitive diagnostic programs. There is provided an interactive capability which allows the user to determine test duration either in terms of a fixed time or in terms of a specified confidence level, the latter case being one in which the system provides the user with an indication of the run time required. Significant improvements over deterministic 'zapping' devices result. The improvement includes solving the equation: ##EQU1## (Where: ##EQU2## as a program step.
