Abstract
Marginal checking by varying supply voltages for some time has been a means of preventive maintenance for electronic systems. Some important innovations have been employed in the marginal checking system of the AN/FSQ-7 air defense computer to give a more effective high-speed preventive maintenance technique. Completely automatic preventive maintenance testing is discussed incorporating program control of the marginal checking system.
