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.
International Standard CISPR 32 has been prepared by CISPR subcommittee I:
Electromagnetic compatibility of information technology equipment, multimedia equipment and
receivers.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) additional requirements using FAR,
b) additional requirements for outdoor unit of home satellite receiving systems,
c) addition of new informative annexes covering GTEM and RVC,
d) numerous maintenance items are addressed to improve the testing of MME.

The text of this publication is based on the following documents:

Emission requirements
1 Scope
NOTE Blue coloured text within this document indicates text that will be aligned with the future MME immunity
publication CISPR 35.
This International Standard 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.
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.
In-situ testing is outside the scope of this publication.
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.

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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
CISPR 32 edition 2.1 contains the second edition (2015-03) [documents CIS/I/498/FDIS
and CIS/I/501/RVD], its corrigendum (2016-06) and its amendment 1 (2019-09)
[documents CIS/I/617/FDIS and CIS/I/623/RVD].
In this Redline version, a vertical line in the margin shows where the technical
content is modified by amendment 1. Additions are in green text, deletions are in
strikethrough red text. A separate Final version with all changes accepted is available in
this publication.

International Standard CISPR 32 has been prepared by CISPR subcommittee I:
Electromagnetic compatibility of information technology equipment, multimedia equipment and
receivers.
This second edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) additional requirements using FAR,
b) additional requirements for outdoor unit of home satellite receiving systems,
c) addition of new informative annexes covering GTEM and RVC,
d) numerous maintenance items are addressed to improve the testing of MME.
This publication has been drafted in accordance with the ISO IEC Directives, Part 2.
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

1 Scope
NOTE Blue coloured text within this document indicates text that will be aligned with the future MME immunity
publication CISPR 35.
This International Standard 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.
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.
The emission requirements in this standard are not intended to be applicable to the intentional
transmissions from a radio communication device operated in accordance with the ITU-R
Radio Regulations, 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 is excluded from the scope of this publication.
In-situ testing is outside the scope of this publication.
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.
