Potential damage to flight hardware from MIL-STD-462 CS02 setup

The MIL-STD-462 CS02 conducted susceptibility test setup includes an audio transformer, with the secondary used as an inductor, and a large capacitor. Together, these two components from an L-type low-pass filter to minimize the injected test signal input into the power source. Some flight hardware power input configurations are not compatible with this setup and break into oscillation when powered up. This, in turn, can damage flight hardware. Such as oscillation resulted in the catastrophic failure of an item tested in the Goddard Space Flight Center (GSFC) large electromagnetic compatibility (EMC) test facility.
