Effective Radiated PowerA standardized theoretical measurement of radio frequency (RF) energy using the SI unit watts. It is determined by subtracting system losses and adding system gains.
Electostatic FieldWhen two objects in each other's vicinity have different electrical charges, an electrostatic field exists between them. An electrostatic field also forms around any single object that is electrically charged with respect to its environment. An object is negatively charged (-) if it has an(...)
Electric FieldThe electric force experienced by a motionless electrically charged test particle at any point in space relative to the source(s) of the field.
Electromagnetic CompatibilityThe branch of electrical sciences which studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (electromagnetic interference, or EMI) that such energy may induce.
EMCThe branch of electrical sciences which studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (electromagnetic interference, or EMI) that such energy may induce.
Electromagnetic DisturbanceDisturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics and electrical equipment.
Electromagnetic FieldA physical field produced by electrically charged objects. Also known as EM Field or EMF.
EMFA physical field produced by electrically charged objects. Also known as EM Field or EMF.
Electromagnetic InterferenceDisturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
EMIDisturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
Electromagnetic PulseA short burst of electromagnetic energy. Also known as EMP or transient distrubance.
EMPA short burst of electromagnetic energy. Also known as EMP or transient distrubance.
Electromagnetic RadiationForm of energy emitted and absorbed by charged particles which exhibits wave-like behavior as it travels through space.
Electronic ChokeA version of a passive two-terminal electronic component called an inductor which is designed specifically for blocking higher-frequency alternating current (AC) in an electrical circuit, while allowing lower frequency or DC current to pass.
Electrostatic DischargeSudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
ESDSudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
EMI FilterFilter that is placed between an electronic equipment and a line external to it, to attenuate conducted radio frequencies between the line and the equipment.
EMI ReceiverA receiver with defined IF-Bandwidths (typically 200 Hz, 9 kHz, 120 kHz, 1 MHz) and standardized detector modes (peak, quasipeak, average, rms, CISPR-AV and CISPR-RMS, RMS-Average). It uses a preselection for an improved dynamic range.
EN 300 386 V1.6.1Covers the EMC requirements for non-radio equipment intended to be used within a public telecommunications network, which provides telecommunications between Network Termination Points (NTPs) (i.e. excluding terminal equipment beyond the NTPs)
EN 301 489-1 V1.9.2Contains the common requirements for radio communications equipment and associated ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC).
