ABSTRACT:
A tester simulates high energy pulses typically present at the inputs to an avionics device after an aircraft carrying the avionics device has been struck by lightning. The tester is used to assist in determining whether the avionics device is sufficiently protected against the effects of a lightning strike on the aircraft. The tester includes a trigger circuit for generating trigger signals at fixed or random intervals so that the pulses which make up each burst as well as the bursts themselves are generated at fixed or random intervals. A number of individual pulse generating circuits are provided to generate high energy pulses which are output to the avionics device under test. A sequencing circuit feeds the trigger signals to the pulse generating circuits so as the generate the high energy pulses and bursts at the selected fixed or random intervals.
