Circuits Control Test Power-Turn-On and -Turn-Off Transients

Two electronic circuits that generate controlled power-turn-on and power-turn-off transients have been developed. These circuits are parts of a suite of test equipment used to measure the responses, to power-bus transients, of power supplies and power-consuming electronic circuitry aboard the space shuttle. These circuits can also be used in testing responses to power-bus transients in other closed electronic systems that include power sources and power-consuming equipment.
