Full Description

Scope

This standard sets forth uniform methods of measurement of radio noise emitted from low-voltage electrical and electronic equipment, including digital and other information technology equipment UTE), in the frequency range of 9 kHz to 40 GHz. Methods for the measurement of radiated and power-line conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods are not currently intended for measurement of deliberately radiated energy, such as that from intentional emitters, nor is this standard intended for certification/approval of avionic equipment, except where specifically referenced. Methods of measurement of various types of intentional emitters are under consideration. These methods apply to the measurement of individual units or systems comprised of units. Additional methods may be added to this standard to fulfill future requirements as needed. The methods used for validation of test sites such as open area sites and absorbed-lined rooms for frequencies in the range of 30-1000 MHz are contained in this standard. Further work on absorbed-lined room validation is under consideration. An effort has been made, wherever possible, to harmonize the measurement procedures contained herein with those in effect nternationally.

Abstract

New IEEE Standard - Superseded. U.S. consensus standard methods, instrumentation, and facilities for measurement of radio-frequency (RF) signals and noise emitted from electrical and electronic devices in the frequency range 9 kHz to 40 GHz are specified. This standard does not include generic nor product-specific emission limits. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes.
