![]() ![]() EEE or E 3 - Electromagnetic Environmental Effects The impact of the electromagnetic environment upon the operational capability of military forces, equipment, systems, and platforms. DUT - Device Under Test The device being evaluated by an EMC test (see also EUT). The strength of the signal is determined by a forward power measurement. DPI - Direct Power Injection A type of conducted immunity test where a continuous wave signal is injected directly onto a cable or component pin (usually through a capacitor). CW - Continuous Wave A sinusoidal waveform with a constant amplitude and frequency. CSA - Canadian Standards Association The Canadian Standards Association is a not-for-profit membership-based association serving business, industry, government and consumers in Canada and the global marketplace. CS and CI describe similar tests, but CS is typically used in military and aerospace testing. ![]() These tests are used to determine the ability of equipment or circuits to withstand or reject electrical noise. CS - Conducted Susceptibility A term used to describe EMC tests where energy is directly coupled onto cables and wires. CISPR - Committee on Special International Committee on Radio Interference CISPR is an international organization concerned with developing standards for detecting, measuring and comparing electromagnetic interference in electric devices. CI and CS describe similar tests, but CI is typically used in commercial EMC testing. ![]() CI - Conducted Immunity A term used to describe EMC tests where energy is directly coupled onto cables and wires. CENELEC’s mission is to prepare voluntary electrotechnical standards (including EMC standards) that help develop the Single European Market/European Economic Area for electrical and electronic goods and services removing barriers to trade, creating new markets and cutting compliance costs. CENELEC - Comité Européen de Normalisation Electrotechnique In English, the name of this committee is the "European Committee for Electrotechnical Standardization". CE - Conducted Emissions The energy generated by a circuit or equipment which is conducted on wires and cables. The charged device model is an alternative to the human body model (HBM), which is similar but with generally higher resistance. In its most basic form, it consists of a charged capacitor, resistor and a switch in series. CDM - Charged Device Model A model for electrostatic discharge sources. BCI - Bulk Current Injection A type of EMC test where common-mode currents are induced on the power and communications cables of the device under test. ![]() APLAC - Asian Pacific Laboratory Accreditation Cooperation APLAC is a cooperation of accreditation bodies in the Asia Pacific region that accredit laboratories, inspection bodies and reference material producers. ANSI - American National Standards Institute ANSI is an organization that sponsors and supports various standards including the EMC radiated emissions test standard, ANSI C63.4. ALSE - Absorber-Lined Shielded Environment An EMC test environment consisting of a shielded room with material on the walls and ceiling that absorbs electromagnetic radiation. AM - Amplitude Modulation A technique for putting information on a sinusoidal "carrier" signal by varying the amplitude of the carrier. Antenna factors are functions of position and frequency. EMC Acronyms and Definitions AF - Antenna Factor The ratio of the received field strength to the voltage appearing at the terminals of a receiving antenna OR the ratio of the transmitted field strength at a specified distance to the voltage applied to the terminals of a transmitting antenna. ![]()
