The scope of this standard is to develop a standard method of measurement for evaluating the electromagnetic and radio frequency supression capability of filters in the frequency range of 100 Hz to 10 GHz. This will apply to EMI/RFI filters in general i.e. DC, single phase or poly phase systems rated for 600 Volts and below 1000 Amps. The method of measurement will describe general considerations, such as method of standardizing source impedance for nonlinear loads, temperature rise,… read more attentuation measurement, components, and or derating requirements when supplying non-sinusoidal load currents and operating in matched or mismatched impedance enviroments. read less

This standard provides methods for determining antenna factors (AFs) and associated parameters of antennas used to perform radiated emission measurements in electromagnetic interference (EMI) control from 9 kHz to 40 GHz. Antennas covered by this standard are linearly polarized antennas, such as loops, rods (monopoles), tuned dipoles, biconical dipoles, log-periodic dipole arrays, hybrids (i.e., combination broadband dipole and log-periodic dipole array antennas), broadband horns, etc., that… read more are used in measurements defined by various ASC C63(R) emission measurements standards (e.g., ANSI C63.4 and ANSI C63.10).4 The associated compliance measurement requirements are provided within other ASC C63(R) standards. The methods used for antenna calibration measurements include the standard site method (SSM), the reference antenna method (RAM), the equivalent capacitance substitution method (ECSM), the standard transmit loop method (STLM), the standard antenna method (SAM), and the standard field method (SFM). In 4.1, the latter three methods are included in this document by reference. read less
