The increasing complexity of weapon systems has lead to a system comprised of multiple electronic, electric, or electromechanical subsystems. Inherent in this situation is the possibility that the emissions of one subsystem will degrade the performance of another and thereby have a negative impact on the entire system as a whole. The purpose of EMC testing is to explore and document this phenomenon. All EMC testing conducted at WSMR is performed in accordance with MIL-STD-E-605D.
