Overview

CISPR 16-1-4:2010/AMD2:2017 is an important amendment issued by the International Electrotechnical Commission (IEC) that updates specifications for radio disturbance and immunity measuring apparatus. This document, part of the CISPR 16 series, focuses specifically on antennas and test sites used for radiated disturbance measurements. It addresses methods, equipment characteristics, and calibration criteria necessary to ensure reliable electromagnetic compatibility (EMC) testing, particularly for radiated emissions and immunity in the frequency range of 1 GHz to 18 GHz.

This amendment contributes to the standardization of measuring apparatus used globally to assess radio disturbances and immunity in electronic and electrical equipment, supporting robust and consistent EMC compliance testing.

Key Topics

  • Scope and Purpose:
    The amendment updates the technical requirements for antennas and test sites used in radiated disturbance measurements. It ensures the accuracy and reproducibility of EMC measurements by specifying antenna types, radiation patterns, and test set-up conditions.

  • Antenna Requirements:

    • Receive (RX) antennas must be linearly polarized and match the types used for Equipment Under Test (EUT) emission measurements.
    • Radiation patterns (E-plane and H-plane) are defined relative to the mechanical boresight, with detailed measurement procedures specifying step sizes and normalization.
    • Half-power beam-width requirements ensure sufficient illumination of the EUT, considering EUT dimensions and test distances to maintain measurement integrity.
  • Test Site Conditions:

    • Specific criteria are included for validating test volumes where EUTs smaller than the validated size are tested, maintaining antenna positioning aligned with original calibration distances.
    • The amendment reinforces the importance of antenna pattern stability over the antenna’s life cycle to guarantee consistent measurement results.
  • Transmit (TX) Antenna Characteristics:

    • TX antennas used during immunity testing must have a linearly polarized radiation pattern with well-documented performance across frequencies, typically measured with steps smaller than 1 GHz.
    • The antennas used for transmission in S testing procedures support simulation of low-directivity radiation patterns of equipment under test.
  • Terminology and Abbreviations:
    New terms such as mechanical boresight-the geometric direction of the main beam of an antenna-are introduced, alongside abbreviations RX (Receive) and TX (Transmit), clarifying communication within the EMC testing community.

Applications

  • EMC Compliance Testing:
    CISPR 16-1-4:2010/AMD2:2017 provides critical guidance for laboratories performing radiated disturbance and immunity tests on electronic devices, ensuring equipment passes international EMC standards.

  • Test Site Calibration and Validation:
    The amendment supports calibration procedures for antennas and the validation of test sites, particularly semi-anechoic chambers and open-area test sites (OATS), improving measurement accuracy.

  • Antenna Design and Manufacturing:
    Manufacturers of EMC antennas use this standard to verify that their antenna models meet criteria for radiation pattern and stability, ensuring suitability for high-precision EMC testing.

  • Measurement Equipment Development:
    The defined performance and pattern requirements aid developers of EMC measurement apparatus in designing antennas and test systems compatible with global standards and regulatory frameworks.

Related Standards

  • CISPR 16-2-3:2010
    Defines methods of measurement for radiated disturbance and immunity testing, referenced in the amendment to align antenna and test procedures.

  • CISPR 16-1-6:2014 and CISPR 16-1-6:2014/AMD1:2016
    Provide specifications for EMC antenna calibration, which complement the antenna requirements detailed in this amendment.

  • IEC Standards on EMC Testing Equipment
    Globally recognized documents detail broader EMC testing requirements and methods, ensuring consistent international applicability.


Adhering to CISPR 16-1-4:2010/AMD2:2017 ensures precise and standardized radiated disturbance and immunity measurements across industries, reinforcing EMC compliance and fostering electromagnetic environment integrity worldwide. For EMC test laboratories, antenna manufacturers, and regulatory bodies, this amendment is a critical reference to maintain measurement quality and alignment with international standards.

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.
