Typically, a given run of tests for a particular piece of equipment will require an EMC test plan and a follow-up test report. The full test program may require the production of several such documents. Emissions are typically measured for radiated field strength and where appropriate for conducted emissions along cables and wiring.
CISPR is the acronym of Comité International Spécial des Perturbations Radio, [1] or the International Special Committee for Radio Protection of IEC. CISPR Standards aim to the protection of radio reception in the range 9 kHz to 400 GHz from interference caused by operation of electrical or electronic appliances and systems in the electromagnetic environment.
Usually, the electrical appliance must be factory tested with standards for conducted emission, as the list of common EMC test standards denotes. Moreover, different manufacturers hold different versions of these standards as fit best to their appliances and warranty schemes. Fig. 2. Conducted Emissions from a commercial DC buck converter
A line impedance stabilization network (LISN) [1] is a device used in conducted and radiated radio-frequency emission and susceptibility tests, as specified in various electromagnetic compatibility (EMC)/EMI test standards (e.g., by CISPR, International Electrotechnical Commission, CENELEC, U.S. Federal Communications Commission, MIL-STD, DO-160 Sections 20-21-22).
A TEM or transverse electromagnetic cell is a type of test chamber used to perform electromagnetic compatibility (EMC) or electromagnetic interference (EMI) testing. It allows for the creation of far field electromagnetic fields in a small enclosed setting, or the detection of electromagnetic fields radiated within the chamber.
The current version of the IEC standard is the second edition dated 2008-12-09. [1] The basic standards (61000-4) are usually called by product or family specific standards, which use these basic standards as a common reference.
MIL-STD-461 [1] is a United States Military Standard that describes how to test equipment for electromagnetic compatibility.. The United States Department of Defense issued MIL-STD-461 in 1967 to integrate electromagnetic compatibility into the research and development stage for defense communications technology. [2]
The FCC logo or the FCC mark is a voluntary mark employed on electronic products manufactured or sold in the United States which indicates that the electromagnetic radiation from the device is below the limits specified by the Federal Communications Commission and the manufacturer has followed the requirements of the Supplier's Declaration of Conformity authorization procedures.
