CISPR 22:2008

This amendment to the fifth edition of CISPR 22 specifies emission limits and method of measurement of radiated disturbances in the frequency range 1 GHz to 6 GHz.

Applies to information technology equipment (ITE). Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this standard is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.

CISPR 32:2015 applies to multimedia equipment (MME) as defined in 3.1.24 and having a rated r.m.s. AC or DC supply voltage not exceeding 600 V. This publication covers two classes of MME (Class A and Class B). The MME classes are specified in Clause 4. The objectives of this publication are: 1) to establish requirements which provide an adequate level of protection of the radio spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to 400 GHz; 2) to specify procedures to ensure the reproducibility of measurement and the repeatability of results. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. The contents of the corrigendum of June 2016 have been included in this copy.
