Emission requirements
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

ELECTROMAGNETIC COMPATIBILITY

Emission requirements
1 Scope
NOTE Blue coloured text within this document indicates text aligned with CISPR 35.
This International Standard applies to multimedia equipment (MME) as defined in 3.1.23 and
having a rated r.m.s. AC or DC supply voltage not exceeding 600 V.
Equipment within the scope of CISPR 13 or CISPR 22 is within the scope of this publication.
MME intended primarily for professional use is within the scope of this publication.
The radiated emission requirements in this standard are not intended to be applicable to the
intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious
emissions related to these intentional transmissions.
Equipment, for which emission requirements in the frequency range covered by this
publication are explicitly formulated in other CISPR publications (except CISPR 13 and
CISPR 22), are excluded from the scope of this publication.
This document does not contain requirements for in-situ assessment. Such testing is outside
the scope of this publication and may not be used to demonstrate compliance with it.
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.

xDSL Generic term for all types of DSL technology
4 Classification of equipment
This standard defines Class A equipment and Class B equipment associated with two types of
end-use environment.
Class A equipment is equipment which meets the requirements given in Table A.2, Table A.3,
Table A.8, and Table A.10, using the limitations defined in Table A.1 and Table A.7.
Class B equipment is equipment which meets the requirements given in Table A.4, Table A.5,
Table A.6, Table A.9, Table A.11 and Table A.12, using the limitations defined in Table A.1
and Table A.7.
The Class B requirements for equipment are intended to offer adequate protection to
broadcast services within the residential environment.
Equipment intended primarily for use in a residential environment shall meet the Class B
limits. All other equipment shall comply with the Class A limits.
Broadcast receiver equipment is class B equipment.
NOTE Equipment meeting Class A requirements may not offer adequate protection to broadcast services within a
residential environment.
5 Requirements
The requirements for equipment covered within the scope of this publication are defined in
Annex A.
6 Measurements
6.1 General
This clause defines the measurement facilities and instrumentation specific to the
measurement of emissions from MME; it includes by reference the relevant basic
requirements given in the CISPR 16 series and other standards shown in the normative
references in this standard. It also defines how to configure and arrange the EUT, local AE
and associated cabling, and provides the relevant measurement procedures.
The specification of the measurement facility, measurement equipment, procedures, and the
arrangement of the measurement equipment to be used are given in the basic standards
referred to in the tables in Annex A. Unless otherwise specified, the basic standards shall be
used for all aspects of the measurement.
Where there are conflicts in the information presented in the CISPR 16 series and this
publication, the content of this publication takes precedence.
The procedures to be used for measurement of emission levels depend upon several
elements. These include but are not limited to:

CISPR 32  IEC:2012 – 15 –
• the type of EUT,
• the type of port,
• the types of cables used,
• the frequency range,
• the mode of operation.
If a single port satisfies the definition of more than one of the types of port defined in this
publication, it is subject to the requirements for each of the port types that it satisfies. Where
a port is specified by the manufacturer for use with both screened and unscreened cables, the
port shall be evaluated with both cable types.
6.2 Host systems and modular EUT
This subclause describes how to configure EUTs that are a host system or modular in nature.
Modular systems can comprise different types of module(s), for example the EUT can be:
• an external module, for example an infra-red remote control;
• an internal module, for example a computer hard disk;
• a plug-in module, for example a memory stick;
• a mounted module, for example a sound card or a video card.
Modules intended to be marketed and/or sold separately from a host shall be assessed with at
least one representative host system. The modules may be internal, mounted, plug-in or
external as illustrated in Figure 2. The port(s) of any module being assessed shall be
terminated in accordance with Annex D. The functions of the host device that are specific to
the module being assessed shall be exercised during the measurements. Modules shown to
meet the requirements of this publication in any one representative host are deemed to meet
the requirements of this publication when used in any host. The host and modules used
during measurements shall be listed in the test report.
