____________
Replace the existing title of this standard by the following new title:
Specification for radio disturbance and immunity measuring apparatus and methods –
Part 1-5: Radio disturbance and immunity measuring apparatus – Specifications and
validation procedures for CALTS and REFTS from 30 MHz to 1 000 MHz

1 Scope
Replace the first paragraph of this clause by the following new paragraph:
This part of CISPR 16 specifies the requirements for calibration test sites used to perform
antenna calibrations and for reference test sites used to measure the antenna-pair reference
site attenuation for compliance test site validations. It describes the test antenna
characteristics, calibration and reference test site verification procedures and site compliance
criteria. Further information on calibration site requirements, test antenna considerations and
the theory of antennas and site attenuation is provided in informative annexes.
2 Normative references
Replace, in the existing list of references, the reference to “CISPR 16-1-4:2003” by the
following new reference:
CISPR 16-1-4:2010, Specification for radio disturbance and immunity measuring apparatus
and methods – Part 1-4: Radio disturbance and immunity measuring apparatus – Antennas
and test sites for radiated disturbance measurements

CISPR 16-1-5 Amend. 1 © IEC:2012 – 3 –
3.1
calibration test site (CALTS)
Replace the existing definition by the following new definition and new note:
open-area test site with metallic ground plane and tightly specified site attenuation
performance in horizontal electric field polarization
NOTE A CALTS is used for the measurement of height dependent AF, and by the standard site method to
measure free-space AF. A CALTS can also be validated for vertical polarization via 4.7. See the related definition
of a REFTS.
3.6
site attenuation
Replace the existing term and definition by the following new term and definition:
site attenuation
SA
minimum site insertion loss measured between two polarization-matched antennas located on
a test site when one antenna is moved vertically over a specified height range and the other is
set at a fixed height
Add, after the existing term 3.8, the following new terms and definitions 3.9 and 3.10:
3.9
site insertion loss
transmission loss between a pair of antennas placed at specified positions on a test site,
when a direct electrical connection between the signal generator output and the measuring
receiver input is replaced by transmitting and receiving antennas placed at the specified
positions
3.10
reference test site
REFTS
open-area test site with metallic ground plane and tightly specified site attenuation
performance in horizontal and vertical electric field polarizations
NOTE Site attenuation measurements of a REFTS are used for comparison to corresponding site attenuation
measurements of a COMTS to evaluate the performance of the COMTS.
4 Specifications and validation procedures for a test site to be used to
calibrate antennas in the frequency range of 30 MHz to 1 000 MHz
Replace the existing title of this clause by the following new title:
4 Specifications and validation procedures for CALTS and REFTS from 30 MHz
to 1 000 MHz
Replace, in the last sentence of this subclause, “5.6 of CISPR 16-1-4” by “5.2.6 of
CISPR 16-1-4”.
4.1 Introduction
Replace the existing title of this subclause by the following new title
4.1 General
Replace the existing second paragraph of this subclause by the following new paragraph:

– 4 – CISPR 16-1-5 Amend. 1 © IEC:2012
In order for a CALTS to be used as a reference test site for validating the performance of test
sites according to Clause 5 of CISPR 16-1-4, the CALTS should be verified using both
horizontal and vertical antenna polarizations, as described in 4.7, whereupon it qualifies for
use as a REFTS. Test sites specified in Clause 5 of CISPR 16-1-4 that are used for
demonstrating compliance with radiated emission limits are referred to herein as compliance
test sites (COMTS). Validation of a COMTS may be obtained by comparing it to the
theoretical site attenuation given in Clause 5 of CISPR 16-1-4, or by comparing the site
attenuation measured on a REFTS to the corresponding site attenuation measured on the
COMTS, using the same antennas and the same antenna set-up geometry.
4.2.2 Normative specification
Replace the existing text of this subclause, including Notes 1 and 2, by the following new text:
For the calibration of antennas, the CALTS shall comply with the validation criteria given in
4.5.3.1 at all frequencies at which the antennas shall be calibrated. The tests in 4.4.3.2 and
their associated criteria in 4.5.3.2 and 4.5.3.3 are optional, but are included for those who
want to confirm the achievement in 4.5.3.1 of T (f) to less than 0,7 dB.
SA
4.6.2 Validation report requirements
Replace, in the existing first sentence of item b), "(see 4.2.2a)" by "(see 4.2.2)".
4.7 Validation of the CALTS for vertical polarization
Replace the existing title of this subclause by the following new title:
4.7 Validation of a REFTS
Delete the existing text of this subclause “Under consideration.”
4.7.1 Introduction
Replace the existing title of this subclause by the following new title:
4.7.1 General
Add the following new text to this subclause:
A REFTS shall meet all requirements of Annex A and be validated with site attenuation
measurements for both horizontal and vertical polarizations. The test antenna for SA
measurements is specified in 4.3. In horizontal polarization SA measurements shall meet the
requirements of 4.4 except 4.4.3.2, 4.4.5 and 4.4.6. The criteria are specified in 4.7.3. Criteria
required for a CALTS described in 4.5.3.2 and 4.5.3.3 are not required for a REFTS. The test
antenna for SA measurements is specified in 4.3. In horizontal polarization SA measurements
shall meet the relevant requirements of 4.4 to 4.6. In vertical polarization SA measurements
shall meet the requirements of 4.7.3.
4.7.2 Site specification
Replace the existing title of this subclause by the following new title:
4.7.2 Site insertion loss measurements for vertical polarization
Add the following new text and subclauses to this subclause:

CISPR 16-1-5 Amend. 1 © IEC:2012 – 5 –
4.7.2.1 General
The following precautions are applicable to vertically polarized antennas in addition to the
requirements for horizontally polarized antennas.
4.7.2.2 Antenna mounting and antenna mast requirements
The antenna separation shall be 10 m. The height of the centre of the transmitting antenna
shall be 2 m, except at 30 MHz, 35 MHz and 40 MHz, where the height shall be 2,75 m. The
frequency and the receive antenna heights shall be chosen according to Table 3.
The bottom tip of the antenna shall be at least 0,25 m above the ground plane. The antenna
mast should be made of low-density dielectric material, and demonstrated to have minimal
effects on the antenna response. Effects of the mast and horizontal boom on the antenna
factor shall be eva
