A system component, such as a circuit card with several circuit modules, is tested during development for its susceptibility to ESD when it is later used as part of a system. Some system components may be poorly shielded by the system enclosure and some components such as high gain circuits are particularly susceptible to ESD. As is conventional in ESD testing, a capacitor is charged to a selected voltage and then discharged across an arc-producing component called a probe. The test simulates various sources of electrical interference, for example, the discharge that frequently occurs when a person walks across a rug in dry weather.
