3.2 Abbreviations
Add to the existing list the following new abbreviations:
DM Differential mode
Δ-AN Artificial Δ-network (‘Δ’ is pronounced ‘delta’)
GCPC Grid connected power convertor
LV Low voltage
RFI Radio frequency interference
UM Unsymmetric mode
V-AMN Artificial mains V-network
V-AN Artificial V-network
Y-AN Artificial Y-network
5.3 Connections to RF reference ground
Delete, in the existing title, the abbreviated term "RF".
Replace the second paragraph (the paragraph following NOTE 1) by the following new
paragraphs:
The measurement of unsymmetric (UM) or terminal voltages and asymmetric (CM) voltages
shall be referenced only to the reference ground. Ground loops (common impedance
coupling) shall be avoided. Ground loops will negatively affect repeatability of measurement
and can, e.g. be detected if grounded components of a test set-up are touch-sensitive. This
should also be observed for measuring apparatus (e.g. measuring receivers and connected
ancillary equipment, such as oscilloscopes, analyzers, recorders, etc.) fitted with a PE
conductor of safety class I equipment.
NOTE 3 A detrimental ground loop can be detected when the components of a test set-up are touch-sensitive, i.e.
the reading changes when the component is touched.
The measuring instrumentation shall be provided with RF isolation so that the AN has only
one RF connection to reference ground. This can be accomplished by using RF chokes and
isolation transformers, or by powering the measuring apparatus from batteries. Figure 1
shows an example of a recommended test set-up with three AMNs and PE chokes for the
avoidance of ground loops. In this figure, also the receiver RF connecting cable to the AMN
can act as a ground connection if the receiver is grounded. Therefore, either a PE choke is
needed at the receiver power input, or, if the receiver is outside a shielded room, a sheath
current suppressor is needed on the connecting cable. Each AMN is thus RF-grounded only
once.
5.4 Connections between the EUT and the artificial mains network
Delete, in the existing title, the word "mains".
Add, after the existing first sentence of this subclause, the following new sentence:
The same guidelines also apply for selection of connections of the EUT to other types of AN
used for the termination of ports other than LV AC mains ports.
6.4.5 Supply
Replace the existing text of this subclause by the following new text:

The EUT shall be operated from a supply having the rated voltage of the EUT. EUTs with
more than one rated voltage shall be tested at the rated voltage which causes maximum
disturbance. Product standards may call for additional measurements at supply voltages
within the rated supply voltage range, if, for example, the levels of disturbance vary
considerably with the actual supply voltage used during the measurements.
7.1 General
Replace the existing item a), including the note, by the following new item:
a) the types of disturbance: there are two methods of measuring conducted disturbances,
either as a voltage (prevailing method for CISPR measurements) or as a current. Both
methods can be used to measure the three types of conducted disturbance, i.e.:
– common mode (also called asymmetric mode, i.e. the vector sum of voltages/currents
in a bundle or group of wires in relation to reference ground);
– differential mode (also called symmetric mode);
– unsymmetric mode (voltage between a terminal of the port under test and reference
ground).
NOTE The unsymmetric voltage is primarily measured at the LV AC mains power port. The CM voltage (or
current) is measured primarily at telecommunication, signal and control ports.
7.3.2.1 General
Replace the existing text of this subclause by the following new text:
The CM, DM and UM impedances of actual networks, such as power mains and
telecommunication networks, are location dependent and, in general, time varying. Therefore,
type testing of disturbance requires standardized impedance simulation networks, referred to
as artificial networks (ANs). The AN provides standardized RF load impedances to the EUT
and simultaneously decouples the laboratory LV AC mains and/or DC power source or other
type of peripheral and ancillary equipment, like a signal simulator, from the EUT. For this
purpose, the AN is inserted between the terminals of the EUT and the actual network or signal
simulator. In this way, the AN simulates extended networks (long lines) with defined
impedances.
7.3.2.2 Types of artificial networks
Replace the existing text, including items a), b) and c), by the following new text:
The ANs specified in CISPR 16-1-2 shall be used, unless specific reasons call for another
construction. In general, three types of AN can be distinguished:
a) V-AN (typically used as V-AMN, or LISN): in a defined frequency range, the RF
impedances between each of the EUT terminals to be measured and the reference ground
have a defined value, whereas no additional separate impedance component is connected
directly between these terminals. The construction defines (indirectly) the measurement of
the vector sum of both the symmetric (DM) and asymmetric (CM) voltages, i.e. of the
composite unsymmetric (UM or terminal) disturbance voltage. In principle, there is no limit
for the number of EUT terminals, i.e. for the number of lines to be measured by V-ANs;
b) Δ-AN: in a defined frequency range, the RF impedances between a pair of EUT terminals
to be measured (and not comprising the grounding terminal) and between the electrical
mid-point of these terminals and the reference ground have defined values. This
construction defines directly both the symmetric (DM) and the asymmetric (CM) RF load
impedances. Addition of a balance/unbalance transformer makes it possible to measure
the symmetric (DM) and asymmetric (CM) disturbance voltages separately. Practical
implementations of Δ-ANs are presently (2016) furnished only with connectors for a total
of three individual EUT terminals, inclusive of common ground;
c) Y-AN (also called the asymmetric artificial network, AAN, or ISN): in a defined frequency
range, the CM RF impedance between the electrical mid-point of a pair of EUT terminals

to be measured and the reference ground has a defined value. In general, no defined
differential load impedance is included in a Y-AN as such. The defined DM impedance
shall then be provided by the external circuit connected to the supply (line) terminals of
the Y-AN. This type of AN is used to measure CM disturbance voltages only.
7.3.3 Current probes
Replace the existing first paragraph by the following new paragraph:
Current probes or current transformers allow the measurement of all three types of
disturbance current (see 7.1 and CISPR 16-1-2) on mains and other power supply leads,
signal lines, load lines, etc. A clip-on construction of the probe will facilitate its use.
7.4 Equipment under test configuration
Replace the existing title by the following new title:
7.4 Configuration of the EUT and method of measurement
7.4.1 Arrangement of the EUT and its connection to the AN
Replace the existing first paragraph by the following new paragraph:
For measurement of the disturbance voltage, the EUT is connected to the laboratory LV AC
and/or DC power supply and any other extended network via one or more AN(s) in
accordance with the following requirements. In general, the V-AMN is used for the LV AC
mains power port (see Figure 9) in accordance with the following requirements. For
termination of LV DC power ports under test, 150 Ω Δ-ANs per CISPR 16-1-2 can be used
(see Figure 26). CISPR product public
