Product Code:SAE ARP1972
Title:Recommended Measurement Practices and Procedures for Emc Testing
Issuing Committee:Ae-4 Electromagnetic Environmental Effects (E3) Committee
Scope:The test methods presented in this document do not represent a modification of an existing set of test methods. Rather, they represent a series of test methods which the committee felt would provide the basic information for any type equipment. A system integrator will need to determine which tests are meaningful to his application. An effort has been made to establish shield room test methods that give results that will approximate those made in an actual installation. A major concern of those involved in preparation of this document is the need to establish meaningful limits for the tests. Measuring emissions on a signal line is only meaningful in conjunction with the susceptibility levels. And these levels are highly dependent on the equipment operating scenario. This area needs to be addressed in the future.
