Specialized EMI test receivers or EMI analyzers are used for EMC compliance testing. These incorporate bandwidths and detectors as specified by international EMC standards. An EMI receiver may be based on a spectrum analyser to measure the emission levels of the DUT across a wide band of frequencies (frequency domain), or on a tunable narrower ...
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.
In 1933, a meeting of the International Electrotechnical Commission (IEC) in Paris recommended the International Special Committee on Radio Interference be set up to deal with the emerging problem of EMI. CISPR subsequently produced technical publications covering measurement and test techniques and recommended emission and immunity limits.
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]
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. [1]
CISPR/TR 30-1 - Test method on electromagnetic emissions- Part 1: Electronic control gear for single- and double-capped fluorescent lamps; CISPR/TR 30-2 - Test method on electromagnetic emissions - Part 2: Electronic control gear for discharge lamps, excluding fluorescent lamps; CISPR 31 - Database on the characteristics of radio services
Electromagnetic testing (ET), as a form of nondestructive testing, is the process of inducing electric currents or magnetic fields or both inside a test object and observing the electromagnetic response. If the test is set up properly, a defect inside the test object creates a measurable response.
