Full title and description

CISPR 16-2-3:2016+AMD1:2019+AMD2:2023 — Specification for radio disturbance and immunity measuring apparatus and methods — Part 2-3: Methods of measurement of disturbances and immunity — Radiated disturbance measurements. This consolidated 2023 release incorporates Amendment 2 to the 2016 edition and updates the methods, definitions and measurement arrangements used for radiated disturbance measurements in the frequency range covered by CISPR.

Abstract

This publication gives the internationally agreed methods for measuring radiated electromagnetic disturbances (radiated emissions) from equipment and systems, including arrangements for antennas, test sites and instrumentation, measurement procedures and references to measurement uncertainty guidance (see CISPR 16-4-x). The document is a basic EMC publication intended to harmonize radiated disturbance measurement practice between laboratories and regulators.

General information

• Status: Published / Current (international standard consolidated with Amendment 2).
• Publication date: 14 June 2023.
• Publisher: IEC / CISPR (international standard; bilingual English/French editions typically published via IEC national publishers).
• ICS / categories: 33.100.10 (Emission); 33.100.20 (Immunity).
• Edition / version: Consolidated edition incorporating CISPR 16-2-3:2016 + AMD1:2019 + AMD2:2023 (often listed as ed.4.2 or CSV consolidated version).
• Number of pages: Consolidated CSV edition: approximately 525 pages; the standalone Amendment 2 change document is published as a shorter amendment file (around 18 pages).

Scope

The standard specifies methods for measurement of radiated disturbances from 9 kHz up to typically 18 GHz, covering antenna and site requirements, receiver and analyser configurations, test procedures for various installations and equipment types, and references for treating measurement uncertainty. It serves as the reference methods document supporting product and regulatory emission testing and national/adopted versions (for example EN adoptions).

Key topics and requirements

• Measurement arrangements for radiated emissions (open-area test sites, semi-anechoic chambers, etc.).
• Antenna calibration, antenna factors and substitution techniques.
• Receiver, spectrum analyser and detector usage for peak, quasi-peak and average measurements.
• Test site validation and site attenuation measurement procedures.
• Reference to measurement uncertainty methods (see CISPR 16-4 series) and procedural controls to ensure repeatability between laboratories.
• Consolidation of previous edition and amendments to reflect updated measurement practice and instrumentation capabilities.

Typical use and users

Used by EMC test laboratories, product manufacturers, test equipment manufacturers, conformity assessment bodies and regulators to define and perform standardized radiated emissions measurements. Also referenced by standards writers when specifying emission limits and test methods for specific product families.

FAQ

Q: What is this standard?

A: It is CISPR 16-2-3 consolidated with Amendment 2 (2023) — the international methods standard for radiated disturbance (emissions) measurements used in EMC testing.

Q: What does it cover?

A: It describes measurement arrangements, antenna and site requirements, receiver/analysers and detector usage, procedural steps for radiated emissions testing (commonly 9 kHz to 18 GHz), and references to measurement uncertainty guidance.

Q: Who typically uses it?

A: EMC test houses, product manufacturers and design teams, test equipment vendors, conformity assessors and regulators use it to ensure consistent, repeatable radiated emission measurements and to support regulatory compliance.

Q: Is it current or superseded?

A: The 2023 consolidated publication (incorporating Amendment 2) is the current consolidated edition published 14 June 2023; it consolidates the 2016 edition and subsequent amendments. National adoptions and harmonized versions (for example EN updates) may follow the consolidated text.
