IEEE/ANSI/USEMCSC C63.9-2024

This standard specifies methods, instrumentation, facilities, and test environments when applying RF immunity requirements for components and subsystems used in multimedia equipment in the frequency range 380 MHz to 7.125 GHz. Specific RF immunity signals (including frequency, power levels, and modulation) and methods of how to apply these are specified so that their functionality can be assessed. The aim is to verify that components, digital devices, or subsystems to be used within MME hosts from different manufacturers have an acceptable performance regarding RF field levels. Measurement methods are included for radiated RF immunity. Definitions are provided for terms and phrases contained in the text, in which the words do not represent obvious or common usage. Measurement instrumentation, facilities, and test environments are specified and characterized, including RF absorber-lined Faraday chambers used for radiated immunity testing. The requirements in this standard shall take precedence. 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. The requirements for the operation of test samples during testing are presented for devices in general, as well as for specific types of devices that are frequently tested. The main text is augmented by a series of annexes that provide details for certain test methods and facilities.

This standard is intended to standardize methods, instrumentation, facilities, and test environments to characterize components of multimedia equipment exposed to a wide variety of common and ubiquitous RF sources from licensed to unlicensed transmitters. The purpose of this standard is to provide methods of evaluating equipment exposed to such threats under controlled conditions to verify that it continues to operate as intended. The specified procedures are intended to be applied in controlled laboratory test environments. Notwithstanding other possible uses, this standard is intended to be used for determining RF susceptibility of unintentional radiators (including digital devices, components, and subsystems) used in multimedia equipment. Regulatory compliance is not implied by use of this standard, as it is intended for components, digital devices, and subsystems of multimedia equipment. Regulatory compliance of the multimedia end-product in which the components, digital devices, or subsystems are used can be required based on regulatory requirements in the country or region it is intended to be used or sold.

Revision Standard - Active. This standard provides recommended test methods and limits for assuring the radio-frequency immunity of multimedia equipment to general use transmitters and other RF sources.
