    Definition
  • The basis for the acceptability criterion of /spl plusmn/4 dB for the site attenuation measurements required in ANSI C63.4-1992 is provided.
  • Information that is useful in constructing an open-area test site (OATS) used to perform radiated emission measurements in the frequency range of 30-1000 MHz is provided. Final validity of the test site can only be made by performing site attenuation measurements as described in ANSI C63.4-1992.
  • Information that is useful in constructing an open-area test site used to perform radiated emission measurements in the frequency range of 30 MHz to 1000 MHz is provided. Final validity of the test site can only be made by performing site attenuation measurements as described in ANSI C63.4-2003.
  • This standard provides recommended test methods and limits for assuring the radio frequency (RF) immunity of office equipment to general use transmitters with transmitter power up to 8 watts.
  • The procedures for testing the compliance of a wide variety of unlicensed wireless transmitters (also called intentional radiators and license-exempt transmitters) including, but not limited to, remote control and security unlicensed wireless devices, frequency hopping and direct sequence(...)
  • This standard republishes CISPR 11:1997 (with Amendment 1, 1999-05) as an American National Standard to make it easily available to U.S. manufacturers.
  • This standard set forth, at least for reference purposes, a suggested set of EMC limits which may find general applications. As part of the development of limits, the following parameters should be considered: an understanding of the devices commonly used for the measurement of radio noise and(...)
  • This recommended practice presents a rationale for developing limits and recommends sets of limits that are representative of current practice. These limits may be adjusted in particular applications as circumstances dictate.
  • A basic understanding of the application, evaluation, and safety considerations of electromagnetic interference (EMI) power-line filters used in both AC and DC applications is provided. The construction of an EMI power-line filter and its functions in providing suppression of conducted noise(...)
  • Terms associated with electromagnetic compatibility (EMC) and electromagnetic environmental effects (E3) are defined in this standard, including electromagnetic pulse (EMP), and electrostatic discharge (ESD) terms. Quantities, units, multiplying factors, symbols, and abbreviations are covered.
  • This immunity measurement and measurement instrumentation specification document complements the recommended procedures for making emission measurements as specified in ANSI C63.4. The immunity methods are alternative methods that might be of use to manufacturers who want to ensure a reliable(...)
  • Based upon ESD events on electronic equipment in actual-use environments, a process to establish ESD test criteria is provided. Test procedures for highly repeatable ESD immunity evaluation of tabletop and floor-standing equipment are described. Simulator characteristics for hand/metal and(...)
  • Specific test procedures for verifying the compliance of unlicensed personal communications services (UPCS) devices (including wideband voice and data devices) are established including applicable regulatory requirements regarding radio-frequency emission levels and spectrum access procedures.
  • Uniform methods of measurement for compatibility between hearing aids and wireless communications devices are set forth in this standard.
  • Uniform methods of measurement for compatibility between hearing aids and wireless communications devices are set forth.
  • Uniform methods of measurement for compatibility between hearing aids and wireless communications devices are set forth. American national standard methods are used for the measurements.
  • Uniform methods of measurement for compatibility between hearing aids and wireless communications devices are set forth.
  • Emission limits are provided that are an are acceptable alternative for limits of the current issue of FCC Part 15, Subpart B, for Information Technology Equipment (ITE). This document republishes CISPR 22 (1993) and Amendment 1 (1995) as an American National Standard, ANSI C63.022-1996, which(...)
  • U.S. consensus guideline for automation of conducted and radiated EMI compliance measurements is provided in this guide. This document does not include mandatory specifications for automation tools (i.e., application software, automated test equipment, computers and peripherals). Where(...)
  • Methods for estimating measurement uncertainty of emissions measurement results are provided, for use in conjunction with the basic methods of ANSI C63.4. Included in this document are both Type A and Type B uncertainty evaluation methods.
