Full title and description

CISPR 16-1-2: Specification for radio disturbance and immunity measuring apparatus and methods — Part 1-2: Radio disturbance and immunity measuring apparatus — Coupling devices for conducted disturbance measurements. The consolidated publication is edition 2.0 (2014) with Amendment 1 (2017), and it specifies characteristics and performance requirements for coupling devices and ancillary apparatus used for conducted disturbance measurements.

Abstract

This standard sets out the requirements for coupling and decoupling networks, artificial mains networks (AMNs), current and voltage probes and other coupling devices used when measuring conducted radio disturbance voltages and currents in the frequency range 9 kHz to 1 GHz. It is a basic horizontal EMC publication intended to harmonize the performance and interaction of measuring apparatus and ancillary equipment used in type and compliance testing.

Scope

Covers the design characteristics, performance and required parameters of coupling devices and ancillary apparatus used for conducted disturbance measurements (including artificial mains networks, coupling/decoupling networks, probes and coupling units for current injection) for the frequency range 9 kHz to 1 GHz. The standard defines standardized RF load impedances, measurement configurations and requirements to ensure repeatable, comparable measurements across test laboratories and product categories.

Key topics and requirements

• Definitions and classification of coupling devices and ancillary apparatus (AMNs, V‑AMN, Δ‑AN, CDNE, AAN).
• Impedance and transfer impedance requirements for artificial mains networks and probes across specified frequency bands.
• Construction, placement and grounding/ground‑loop avoidance measures for AMNs and related equipment in test configurations.
• Performance tolerances, RF isolation recommendations for measuring instruments and ancillary equipment, and guidance for powering/connection to avoid measurement artefacts.
• Requirements for coupling units used for conducted immunity/current injection tests and standardized measurement interfaces.

Typical use and users

Used by EMC test laboratories, test-house engineers, calibration laboratories, manufacturers of measuring receivers and ancillary EMC test equipment, product standards committees that reference EMC test methods, and regulatory/market‑surveillance bodies responsible for ensuring compliance with conducted disturbance limits.
