FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical reports or guides and they are accepted by the National Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60364-7-711 has been prepared by IEC technical committee 64:

Electrical installations of buildings
The text of this standard is based on the following documents:
FDIS Report on voting
64/982/FDIS 64/999/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

Note 1 to entry There are two basic types of this network, the V-network (V-AMN) which couples the unsymmetric

voltages, and the delta-network (Δ-AMN), which couples symmetric (DM) and asymmetric (CM) voltages

separately.
The addition of a new Note 4 to entry applies to the French language only.

Replace the existing definition and note by the following new definition and new notes:

flat, conductive surface that is at the same electric potential as reference ground, which is

used as a common reference, and which contributes to a reproducible parasitic capacitance

with the surroundings of the EUT

Note 1 to entry A reference ground plane is needed for the measurement of conducted disturbances, and serves

as reference for the measurement of unsymmetric and asymmetric disturbance voltages.

Note 2 to entry In some regions, the term ‘reference earth’ is used in place of ‘reference ground’.

Add, after the existing definition 3.1.14, the following new definition and note:

3.1.15
artificial network

network that provides a defined impedance to the EUT at radio frequencies, couples the

disturbance voltage to the measuring receiver, and decouples the test circuit from the mains

network or other power lines or from signal lines with associated equipment

Note 1 to entry There are four basic types of this network, the V-network (V-AN) which couples the unsymmetric

voltages, the delta-network (Δ-AN), which couples symmetric (DM) and asymmetric (CM) voltages separately, the

Y-network (Y-AN) and the coaxial (screened cable) network which couple asymmetric (CM) voltages.

Replace the existing title by the following new title:
4 Artificial networks for AC mains and other power ports
4.1 General

Replace the existing text, including Notes 1 and 2, by the following new text and new notes:

An AN is required to provide a defined impedance at radio frequencies at the terminals of the

EUT's port under test, to isolate the test circuit from unwanted RF signals on the laboratory

AC or DC supply mains, other power source or load connected to the EUT but not subject to

testing in relation with that EUT, and to couple the disturbance voltage to the measuring

receiver.

For use with measurements on LV AC mains power ports, there are two basic types of AMN,

the V-AMN, which couples the unsymmetric voltages, and the Δ-AMN, which couples the

symmetric and the asymmetric voltages separately. Use of practical implementations of these

AMNs is not restricted to LV AC mains power ports. In principle they can be used for

measurements on any kind of power port. The user of such artificial networks is

recommended to consult the respective product standard for guidance. The information and

advice in this standard for the AMN is hence valid for use of that AMN or another AN at power

ports other than LV AC mains power ports.

The AN or AMN is furnished with three ports, the port for connection to the laboratory AC or

DC supply mains or other power source or load (power/load port), the port for connection of

the EUT (EUT port), and the disturbance output port for connection of the measuring receiver

(receiver port).
NOTE 1 Examples of circuits of AMNs and ANs are given in Annex A.

NOTE 2 This clause specifies impedance and isolation requirements for ANs including the corresponding

measurement methods. Some background and rationale on the AMN related uncertainties are given in 6.2.3 of

CISPR/TR 16-4-1:2009 and in CISPR 16-4-2.
4.2 AMN impedance
Replace the existing title by the following new title:
4.2 AN impedances

Replace the existing text, including the note, by the following new text and new note:

The specification of the UM termination impedance of a V-AN includes the magnitude and the

phase of the impedance measured at an EUT terminal with respect to the reference ground,

when the V-AN’s receiver port is terminated with 50 Ω.

In case of a Δ-AMN or Δ-AN, the specification of the termination impedances includes the

magnitude and phase of the asymmetric (CM) termination impedance and the magnitude and

phase of the symmetric (DM) termination impedance. The asymmetric termination impedance

---------------------- Page: 6 ----------------------
CISPR 16-1-2:2014/AMD1:2017 – 5 –
© IEC 2017

is measured with the two (or more) active EUT terminals joined together relative to the

reference ground (as in Figure E.2). The symmetric termination impedance is measured

between each active pair of EUT terminals without relation to reference ground and requires

the use of a balun (see Figure K.2). For the impedance measurements, also for Δ-ANs the

receiver port shall be terminated by 50 Ω.

The impedance at the EUT terminals of the AN defines the termination impedance presented

to the EUT's port under test. For this reason, when a disturbance output terminal is not

connected to the measuring receiver, it shall be terminated by 50 Ω. To assure accurate

termination into 50 Ω of the receiver port, a 10 dB attenuator shall be used either inside or

external to the AN, the VSWR of which (seen from either side) shall be less than or equal to

1,2 to 1. The attenuation shall be included in the measurement of the voltage division factor

(see 4.11).

The impedance between each conductor (except PE, if any) of the EUT port and reference

ground shall comply with the provisions of 4.3, 4.4, 4.5 or 4.6, as appropriate, for any value of

external impedance, including a short circuit connected between the corresponding mains or

other power supply terminal and reference ground of the power/load port. This requirement

shall be met at all temperatures which the AN may reach under normal conditions for

continuous currents up to the specified maximum. The requirement shall also be met for peak

currents up to the specified maximum.

NOTE Because EUT connectors are not optimized for radio frequencies up to 30 MHz, the measurement of the

network impedance is carried out with special measurement adaptors to enable short-length connections. The OSM

(open/short/matched) calibration of the network analyzer is used to characterize the adaptors, taking the insertion

loss and the conductor lengths of the adaptors into account.

4.6 150 Ω artificial mains V-network (V-AMN) for use in the frequency range 150 kHz

to 30 MHz
Replace the existing title and text by the following:

4.7 150 Ω artificial delta-network (Δ-AN) for mains and other power ports for use in

the frequency range 150 kHz to 30 MHz
4.7.1 Requirements

In the frequency range of interest from 150 kHz to 30 MHz the AN shall have an impedance of

magnitude (150 ± 30) Ω with a phase angle not exceeding 40°, both between the EUT

terminals not including reference ground and between these two EUT terminals joined

together and the reference ground; see Table 8.

For proper performance in the range 150 kHz to 30 MHz, the AN shall also meet the

characteristics specified in Table 9 in the frequency range 9 kHz to 150 kHz. Adherence to

these characteristics does not however qualify the 150 Ω Δ-AN for use with measurements of

disturbance voltages in the range below 150 kHz. If necessary, another Δ-AN needs to be

specified for such measurements.

Annex K
(normative)
Measurement of Δ-AN parameters

Most of the typical characteristics of Δ-ANs are measured according to the instructions for

measurements on asymmetric artificial networks (AANs) in Annex E of this standard.

The asymmetric impedance at the EUT port of the Δ-AN is measured according to Figure E.2.

The calibration set-up and the set-up for measurement of the symmetric impedance at the

EUT port of the Δ-AN are shown in Figures K.1 and K.2, respectively.

The LCL of the Δ-AN is measured according to Figure E.5 (however with modified resistor

values for a symmetric impedance of 150 Ω, instead of 100 Ω).

The asymmetric insertion loss between the EUT port and the port of the AN for connection to

the external power source or load is measured according to Figure E.6.

The symmetric insertion loss between the EUT port and the port of the AN for connection to

the external power source or load is measured according to Figure E.7.
The voltage division factor for asymmetric measurements is measured according to
Figure E.8.
