2 Normative references
Replace, in the existing list, the reference to CISPR 16-2-3 by the following:
CISPR 16-2-3:2010, Specification for radio disturbance and immunity measuring apparatus
and methods – Part 2-3: Methods of measurement of disturbances and immunity – Radiated
disturbance measurements
Add, to the existing list, the following new normative reference:
CISPR 16-1-6:2014, Specification for radio disturbance and immunity measuring apparatus
and methods – Part 1-6: Radio disturbance and immunity measuring apparatus – EMC

3.1 Terms and definitions
Add, after the existing 3.1.27 added by Amendment 1, the following the new term and
definition:
3.1.28
mechanical boresight
direction of the main beam, which is defined by the geometric properties of the antenna

3.2 Abbreviations
Add to the existing list the following new abbreviations:

RX Receive
TX Transmit
4.6 Frequency range 1 GHz to 18 GHz

Add, before the existing text, the following new title:

4.6.1 General
Delete, in the third sentence of the first paragraph of the existing subclause, the latter half of
the sentence starting with “or provisions shall be made…”
Add at the end of the existing 4.6 the following new subclauses:
4.6.2 Receive antenna
4.6.2.1 General
The receive antenna shall be linearly polarized and shall be the same type as used for EUT
emission measurements.
Some antenna models may have different versions with possibly different patterns and users
are advised to verify this.
NOTE 1 “Antenna type” means a shape or a kind of antenna, for example horn and LPDA antenna.
NOTE 2 “Antenna model” means the specified manufacturer’s model number.
NOTE 3 “Version” means the specified manufacturer’s revision number, if applicable, of a particular antenna
model number.
4.6.2.2 Receive antenna radiation pattern
E-plane and H-plane radiation patterns shall be measured with reference to the boresight.
The measurand is the antenna pattern in dB and as represented on the polar chart in
Figure 43.
The normalization of this chart is to 0 dB.

The 0º angle shall be equal to the mechanical boresight.
The E-plane and H-plane radiation patterns of each individual antenna shall be recorded over
the frequency range of the antenna with a step size of 500 MHz or smaller according to
Annex I of CISPR 16-1-6:2014/AMD1:2016.
Type test results, including statistical data, supplied by the manufacturer may be used to
provide evidence that the receive antenna radiation pattern requirements are met. Service
measures shall be taken to assure pattern stability during the antenna life.

Figure 43 – RX antenna E-plane radiation pattern example with limit for
3 m distance and 2 m EUT width
NOTE In general, the boresight direction is the direction of maximum radiation from the antenna, However it may
happen that the pattern has two radiation maxima and none of the maxima are in the direction of the mechanical
boresight as in Figure 43.
4.6.2.3 Receive antenna radiation pattern requirements
The grey areas shown in the polar diagrams of Figures 44 and 45 are defined by the
maximum height, h, and the maximum width, w, of the EUT and the test distance, d.
In order for the receive antenna to sufficiently illuminate the EUT, the half power beam-width
of the receive antenna shall not fall inside this area in E-plane and H-plane cuts as shown in
Figures 44 and 45.
w
0 dB

w = maximum width of the EUT

8.3.1 General
Add, between the third and fourth paragraphs, the following new paragraph and new NOTE 3:
When measuring the disturbance of an EUT size smaller than the validated diameter, the
diameter of the validated test volume is assumed to apply. In this case the antenna position is
adjusted such that the distance between the EUT and the antenna reference point is identical
to the distance used for S validation.
VSWR
NOTE 3 For EUTs smaller than the validated test volume, the rationale is that the RX antenna position in relation
to the front of the EUT be adjusted to remain at the distance used in S validation. It is assumed that a smaller
VSWR
EUT will remain within the half power beam-width of the RX antenna and since the chamber is validated for the
largest EUT and therefore the widest beam-width of the RX antenna, the requirements of 7.6.6.1 in CISPR 16-2-
3:2010 are met.
8.3.3.1.1 General
Replace the existing text of this subclause by the following new paragraphs and note:
To provide illumination of all reflecting surfaces during this test, and to simulate the possible
low-directivity radiation patterns exhibited by many EUTs, this subclause specifies
characteristics for equipment used for S testing. For this purpose, RX and TX antennas
VSWR
are used.
The following subclauses define the performance criteria for the TX antennas for the S
VSWR
test. For the performance criteria of RX antennas see 4.6.2.3. Type test results supplied by
the manufacturer may be used to provide evidence that the performance criteria are met.
The TX and RX patterns shall be measured according to Annex I of
CISPR 16-1-6:2014/AMD1:2016.
For both the TX and RX antennas, one or more antennas can be used to cover the whole
frequency range for the S test.
