Annex A
(normative)
Requirements
A.1 General
Add, after the first paragraph of this clause, the following new paragraph:
When the excluded transmissions from a radio communication device (as defined in Clause 1)
appear in a measured conducted or radiated emission spectrum, those signals do not need to
be reported and shall not be considered in identifying the top six emissions for reporting (see
Clause 9). The test report may indicate that the signals were observed and were identified as
being excluded transmissions.
Replace the existing fourth paragraph of this clause starting with "Other measurement
methods." with:
Other measurement methods and associated limits for RVCs and GTEM cells are presented in
Annex I for information, however, they cannot be used for demonstrating compliance with this
publication.
A.2 Requirements for radiated emissions
Replace the existing second paragraph of this clause by the following new text and new figure:
Measurements for showing compliance shall only be performed at measurement distances for
which the test site is compliant with the appropriate test site validation requirements and
restrictions defined in Table A.1. In addition, for facilities covered by Table clause A1.1, this
includes any receive antenna position between (and including) R1 to R2 as given in Figure A.2
that results in a test distance meeting the requirements defined in Table D.2. These antenna
positions are those used during the test site validation.
In Figure A.2, the circle defines the maximum allowable EUT volume from the test site validation.

4, 5, 6 and 7. Detectors and bandwidths shall be used as specified in relevant tables in Annex A
of CISPR 16-1-1:2015. Where this publication specifies the use of an average detector, the
linear average detector defined in Clause 6 of CISPR 16-1-1:2015 shall be used.
C.2.2.2 Antennas for radiated emissions measurements
Replace the last sentence of this subclause with the following and add the new note as follows:

NOTE Previously, CISPR 32 referenced ANSI C63.5 for antenna calibration requirements. In order to simplify the
transition to these new requirements, the test laboratory should have their antennas calibrated using methods defined
in CISPR 16-1-6:2014/AMD1:2017 which emulate those of ANSI C63.5, using the antenna calibration facilities defined
in CISPR 16-1-5:2014/AMD1:2016. This may include using a CALTS (calibration test sites) for the frequency range
below 1 GHz and a FAR above 1 GHz.

Add the following text and figures after Table C.1:
A wired network port intended for connection to an unscreened balanced pair cable, that uses
a transmission technology where the defined injected power does not exceed the power spectral
density (PSD) limits given in the equations below then the conducted emissions at the wired
network port may alternatively be measured using one of the following methods in order of
precedence:
1) AAN methodology as defined in C.4.1.6.2 with the highest LCL value that doesn’t
interrupt normal operation.
2) the non-invasive methodology as defined in C.4.1.6.4.
Measurements may still be made using the AAN methodology with the appropriate LCL, in
accordance with C.4.1.6.2, if preferred. If the wanted signals of the transmission technology
have a Quasi-peak to Average ratio greater than 10 dB, the conducted emission measurement
shall be performed using the AAN methodology with the appropriate LCL, in accordance with
C.4.1.6.2 or if the port is unable to function correctly the methodology defined in C.4.1.6.4.

NOTE There are many ITU-T recommendations that define PSD masks for wireline transmission systems. Standards
defining PSD measurement techniques are limited, examples can be found in ATIS 0600417 and NICC ND1602.
EXAMPLE ITU-T recommendation G.993.2:2019 defines PSD masks in A.2, B.2 and C.2. Taking the PSD masks
defined in B.2.3 Table B.7 as an example they are all below the PSD limits defined above for a Class B EUT for a
Category 3 cable (See Figure C.11 example below showing Masks B8-1 to B8-7 from G.993.2). Therefore a wired
network port conforming to these masks could follow the procedure given in C.4.1.6.2 to measure the conducted
emissions but using an AAN with the highest LCL; or, if the port is still unable to function correctly with such an AAN
then the non-invasive methodology as defined in C.4.1.6.4 is used.

C.4.1.2 Characteristics of AAN

Replace the existing first paragraph with the following new paragraph (moved from C.4.1.6.2):
When emission voltage measurements are performed, the AAN shall provide a voltage
measurement port suitable for connection to a measuring receiver while simultaneously
satisfying the analogue/digital data port common mode termination impedance requirements.
Replace, in item e), "the requency range" by "the frequency range".
C.4.1.3 Selection of AAN for unscreened balanced multi-pair cables
Replace the second existing paragraph with the following new paragraph:
Examples of AANs are shown in Annex G. The AAN described in Figure G.4 to Figure G.7 and
Figure G.18 to G.21 are only appropriate for use where there are no unconnected pairs in the
cable. The AANs shown in Figure G.1 to Figure G.3 are suited to any situation, including those
where the use of some of the pairs is unknown, or some pairs are known to be unconnected.
The AAN examples shown in Figures G.16 to G.21 are designs with either an asymmetrical
transformer or improved shunt arrangement. These ensure the common mode impedance of
the EUT does not affect the measurement and are recommended for measurements at wired-
network ports with low LCL.

Annex D
(normative)
Arrangement of EUT, local AE and associated cabling
D.1.1 General
Add, between the first paragraph and the second paragraph, the following new paragraph:
This annex defines the arrangement of the EUT, local AE and associated cabling. This standard
does not define the use of CMADs for radiated emission measurements and so they shall not
be placed on cables leaving the test site.
Replace the existing seventh paragraph with the following new paragraph:
Cables connecting to AE located outside the measurement area shall drop directly to, but be
insulated from, the RGP (or turntable where applicable), and then be routed directly to the place
where they leave the test site. The thickness of the insulation is specified in Table Clause D2.14
and is separate from any insulation that is part of the cable construction. However, cables which
would normally be bonded to ground should be bonded to the RGP in accordance with normal
practice or the manufacturer’s recommendation.
Replace the existing ninth paragraph with the following new paragraphs:
For conducted emission measurements, where practical, any excessive length in AC mains
cables shall be bundled non-inductively, at the midpoint between the EUT and the AMN. The
bundle length shall be less than 0,4 m to satisfy the distances given in Table D.2. Cables
between the EUT and AAN shall be kept as short as possible, and shall take the most direct
path between the EUT port and the corresponding AAN port, and should not be bundled in order
to meet the arrangement spacing defined in Table D.2.
If a cable requires bundling care should be taken to ensure that the bundle is formed non-
inductively and the cable characteristics are maintained.
For radiated emission measurement, mains cables shall drape vertically to (but be insulated
from) the horizontal ground plane. Where practical, any excessive cable length shall be
arranged non-inductively on the insulation.
Replace the existing twelfth paragraph with following new paragraph:
For conducted measurements, where possible, the effective length of the EUT mains cables
shall be 1 m ± 0,1 m.
Replace the existing second to last paragraph with the following new paragraph:
See Figure D.1 through Figure D.12 for examples of arrangements.
