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 16-1-4:2025 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications for antennas and test sites are included.NOTE In accordance with IEC Guide 107. CISPR 16-1-4 is a basic EMC publication for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC standard. CISPR and its sub-committees are prepared to cooperate with product committees in the evaluation of the value of particular EMC tests for specific products.The requirements of this publication apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating range of the measuring equipment. Methods of measurement are covered in CISPR 16-2-3, further information on radio disturbance is given in CISPR TR 16-3, and uncertainties, statistics, and limit modelling are covered in CISPR 16-4 series. This fifth edition cancels and replaces the fourth edition published in 2019, Amendment 1:2020 and Amendment 2:2023. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) revision of the definition 3.1.7 and of the general introduction 8.1.1 for CMAD;b) introduction of a new cable termination device, the very high frequency line impedance stabilization network (VHF-LISN) in 8.2;c) addition of definition 3.1.34 for VHF-LISN, 3.1.20 for reference ground, 3.1.21 for reference ground plane and 3.1.31 for TN‑C‑S power system;d) various non-technical editorial, style, and wording adjustments for consistency with drafting rules.
