This paper describes a technique of semiautomatic electromagnetic compatibility (EMC) testing that has been developed at the US Army Avionics Laboratory, Fort Monmouth, NJ, USA. The technique was developed to reduce EMC testing effort and to provide a more comprehensive test program. The method used to accomplish the task involves the use of a data acquisition unit integrated into the aircraft avionics and electrical subsystems. This enables the test engineer to gather EMC performance data on the system in its natural environment. The on-board recorded data is subsequently reduced by computer using specially developed programs to determine areas of non-compatibility. The results of the investigation indicate that the technique of using a data acquisition system for EMC testing is feasible and requires less test effort and provides more complete and accurate results than conventional EMC testing.
