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 CISPR 16-2-3 consists of the third edition (2010)
[documents CISPR/A/886/FDIS and CISPR/A/892/RVD and its amendment 1 (2010)
[documents CISPR/A/878/CDV and CISPR/A/894/RVC]. It bears the edition number 3.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

maintenance items are addressed to make the standard current with respect to other parts of
the CISPR 16 series.
It has the status of a basic EMC publication in accordance with IEC Guide 107,
Electromagnetic compatibility – Guide to the drafting of electromagnetic compatibility
publications.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the CISPR 16 series, published under the general title Specification for
radio disturbance and immunity measuring apparatus and methods, can be found on the IEC
website.
The committee has decided that the contents of the base publication and its amendments 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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-161, as well
as the following apply.
3.1
absorber-lined OATS/SAC
OATS or SAC with ground plane partially covered by RF-energy absorbing material
3.2
ancillary equipment
transducers (e.g. current and voltage probes and artificial networks) connected to a
measuring receiver or (test) signal generator and used in the disturbance signal transfer
between the EUT and the measuring or test equipment
3.3
antenna beam
main lobe of the antenna pattern (gain pattern) of the receive antenna (usually the direction
with maximum sensitivity or lowest antenna factor) that is directed towards the EUT
3.4
antenna beamwidth
angle between the half-power (3 dB) points of the main lobe of the antenna beam, when
referenced to the maximum power of the main lobe. It may be expressed for the H plane or for
the E plane of the antenna
NOTE Antenna beamwidth is expressed in degrees.
3.5
associated equipment
AE
apparatus, that is not part of the system under test, but needed to help exercise the EUT
3.6
auxiliary equipment
AuxEq
peripheral equipment that is part of the system under test
3.7
basic standard
standard that has a wide-ranging coverage or contains general provisions for one particular
field

NOTE A basic standard may function as a standard for direct application or as a basis for other standards.
[ISO/IEC Guide 2, definition 5.1]
3.8
coaxial cable
cable containing one or more coaxial lines, typically used for a matched connection of
ancillary equipment to the measuring equipment or (test-) signal generator providing a
specified characteristic impedance and a specified maximum allowable cable transfer
impedance
3.9
common-mode absorption device
CMAD
device that may be applied on cables leaving the test volume in radiated emission
measurements to reduce the compliance uncertainty
[CISPR 16-1-4, 3.1.4]
3.10
conformity assessment
demonstration that specified requirements relating to a product, process, system, person or
body are fulfilled
NOTE The subject field of conformity assessment includes activities defined elsewhere in ISO/IEC 17000:2004,
such as testing, inspection and certification, as well as the accreditation of conformity assessment bodies.
[ISO/IEC 17000:2004, 2.1, modified]
3.11
continuous disturbance
RF disturbance with duration of more than 200 ms at the IF-output of a measuring receiver
that causes a deflection on the meter of a measuring receiver in quasi-peak detection mode,
and that does not decrease immediately
[IEC 60050-161:1990, 161-02-11, modified]
3.12
(electromagnetic) emission
phenomenon by that electromagnetic energy emanates from a source
[IEC 60050-161:1990, 161-01-08]
3.13
emission limit (from a disturbing source)
specified maximum emission level of a source of electromagnetic disturbance
[IEC 60050-161:1990, 161-03-12]
3.14
equipment-under-test
EUT
equipment (devices, appliances and systems) subjected to EMC (emission) compliance
(conformity assessment) tests
3.15
fully-anechoic room
FAR
shielded enclosure, the internal surfaces of which are lined with radio-frequency
