The MIL-STD-1377 specification is specifically for a weapon developer or designer with shielding effectiveness test methods. The actual methods of the shielding effectiveness test are for weapon enclosures, cables, and cable connectors. The weapon enclosure can involve an enclosure that surrounds the weapon circuit, the cable is wiring that starts outside of the enclosure and enters inside and connected to circuits inside the weapon enclosure, and cable connectors are simply what connects everything together for the overall system. The test is performed over a frequency range of 100 kilohertz (kHz) up to 30 megahertz (MHz), then from 1 gigahertz (GHz) to 10 gigahertz (GHz).
As depicted in the figure, test setup is the same as other shielding effectiveness, with the determination of the dynamic range and the actual measurement of the signal for the sample in question. If the system involves a weapon enclosure, all internal components need removed such that only the enclosure is being tested.
