IEEE/ANSI C63.10-2013

This standard specifies U.S. consensus standard methods and instrumentation and test facilities requirements for measurement of radio frequency (RF) signals and noise emitted from unlicensed wireless devices (also called unlicensed transmitters, intentional radiators, and license-exempt transmitters) operating in the frequency range 9 kHz to 231 GHz. It does not include generic or product-specific emission limits. It also does not cover measurement of radio emissions from unintentional radiators, as mentioned in 1.2. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes. Uses of the word shall in this standard indicate a mandatory requirement that must be met to satisfy this standard. The word should is used to indicate that a requirement is recommended but not mandatory. Tolerances on dimensions and distances are based on good engineering practice where not specified. The word may is used to indicate a recommendation that is at the discretion of the user. In addition, notes in this document are informative and are not part of the requirements. In this standard, the text takes precedence over the figures because the text is complete and the figures are illustrative of a typical application of the text. Notes are used in the text for emphasis or to offer informative suggestions about the technical content of the standard, and provide additional information to assist the reader with a particular passage, but they do not include mandatory requirements. Footnotes in text are included only for information, clarification,and/or aid applicable to the use of the standard, but mandatory requirements are not included in text footnotes. Measurement methods are provided for radiated and conducted emissions that can be generated by a variety of devices, as described in 1.2. Definitions are provided for terms and phrases contained in the text, in which the words do not represent obvious or common usage. In most cases, measurement instrumentation and calibration requirements are only generally characterized in deference to standards dedicated to these subjects, which should be used in conjunction with this standard. Requirements for operation of test samples during measurements are presented for devices in general, as well as for specific types of devices that are frequently measured. Specific requirements for emission test data recording and reporting are presented with reference to general requirements contained in documents dedicated to standard laboratory practices, which should be used in conjunction with this standard. The main text is augmented by a series of annexes that provide details for certain measurement methods and facilities.

Various unlicensed wireless devices (also known as unlicensed transmitters, intentional radiators, and license-exempt transmitters) are subject to certain regulatory requirements. The primary way to show compliance in meeting regulatory requirements is by testing such devices in a repeatable and reproducible manner. This standard presents the methods of measurement to show compliance with the technical specifications for the majority of current wireless devices in wide use. It represents a consolidation and elucidation of procedures that were heretofore dispersed throughout many documents. It is not expected that all unlicensed wireless devices on the market will in fact be covered by this standard. This standard does not consider test methods for unlicensed wireless devices already covered in other published standards, such as Unlicensed Personal Communication Services devices, which are covered in ANSI C63.17-2006 [B3].1 Procedures for evaluating dynamic frequency selection (DFS) functionality (i.e., required for U-NII devices in the United States) and for television-band unlicensed wireless devices2 are not addressed in this standard. This standard also does not cover measurement of emissions from radio receivers, the receiver portion of a transceiver, and other types of unintentional radiators, which are covered by other standards (e.g., ANSI C63.4).3 This standard does not cover other types of unintentional radiators (e.g., industrial, scientific, and medical (ISM) equipment). In addition, many types of unlicensed wireless devices are also subject to regulatory requirements concerning human exposure to RF energy; RF exposure conformity assessment methods are not considered in this standard but are the subject of other standards (e.g., IEEE Std 1528TM-2003 [B37]). This document provides standard test methods for determining compliance with regulatory requirements for many types of unlicensed wireless devices. These unlicensed wireless devices include, but are not limited to, the following: -Remote control and security unlicensed wireless devices -Frequency hopping and direct sequence spread spectrum devices -Digital transmission system devices -Antipilferage devices -Cordless telephones -Radio frequency identification (RFID) tag readers -Unlicensed National Information Infrastructure devices -Intrusion detectors -Unlicensed wireless devices operating below 30 MHz -Wireless (garage) door openers -Ultra-wideband (UWB) devices -Automatic vehicle identification systems -Inductive devices

Revision Standard - Superseded. 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 spread spectrum devices, antipilferage devices, cordless telephones, medical unlicensed wireless devices, Unlicensed National Information Infrastructure (U-NII) devices, intrusion detectors, unlicensed wireless devices operating on frequencies below 30 MHz, automatic vehicle identification systems, and other unlicensed wireless devices authorized by a radio regulatory authority are covered in this standard. Excluded by this standard are test procedures for unlicensed wireless devices already covered in other published standards (e.g., Unlicensed Personal Communication Services (UPCS) devices).
