Overview

EN 55016-1-2:2014/A1:2018 (CISPR 16-1-2:2014/A1:2017) specifies requirements for coupling devices used in conducted disturbance measurements. This European amendment updates definitions and technical requirements for artificial networks (AN/AMN), coupling devices and measurement interfaces used when measuring radio disturbance (conducted emissions) and immunity on power and other wired ports. The document is fundamental for EMC test labs, manufacturers and compliance engineers performing conducted emissions and immunity testing.

Key topics and technical requirements

• Scope and status
  • Amendment A1 modifies EN 55016-1-2:2014 and aligns the European text with CISPR 16-1-2:2014/A1:2017.
• Definitions clarified
  • Asymmetric voltage (CM): RF voltage between the electrical mid-point of multi‑wire circuit and reference ground.
  • Symmetric voltage (DM): RF voltage between any pair of wires (not including ground) in a multi‑wire circuit.
  • Unsymmetric voltage (UM): Voltage between an individual conductor and reference ground (measured with V‑AMN).
  • Reference ground plane (RGP) and artificial network (AN) definitions are refined.
• Artificial networks (AN/AMN)
  • AN provides defined RF impedance to the equipment under test (EUT), isolates the test circuit from lab mains and couples disturbance to the receiver.
  • Types: V‑AN / V‑AMN (couples unsymmetric voltages), Δ‑AN / Δ‑AMN (couples symmetric and asymmetric separately), Y‑AN, and coaxial (screened cable) networks.
• Impedance & termination rules
  • Receiver port must be terminated in 50 Ω; a 10 dB attenuator (VSWR ≤ 1.2:1) is recommended to guarantee proper termination and included in voltage division factor measurements.
  • When receiver not connected, disturbance output must be terminated in 50 Ω.
• 150 Ω Δ‑AN specification (150 kHz–30 MHz)
  • Termination impedance: (150 ± 30) Ω, phase angle ≤ 40°.
  • Longitudinal conversion loss (LCL) ≥ 26 dB.
  • Insertion loss ≥ 20 dB (power/load port → EUT port); other requirements include discharge resistor values (≥ 1.5 MΩ) and extended characteristics down to 9 kHz.

Applications and users

• Who uses it: EMC laboratories, product compliance teams, test-house engineers, and product standards committees.
• Practical use cases
  • Setting up and validating conducted emissions and conducted immunity test setups for mains and non‑mains power ports.
  • Selecting or designing artificial networks (V‑AMN, Δ‑AN) to meet defined impedance and isolation criteria.
  • Ensuring reproducible, standardized measurements for product certification and regulatory compliance.

Related standards & keywords

• Related to CISPR 16 family (basic EMC publication) and national implementations of EN 55016‑1‑2.
• SEO keywords: EN 55016-1-2:2014/A1:2018, CISPR 16-1-2, coupling devices, artificial mains network, AMN, V‑AMN, Δ‑AN, conducted disturbance measurements, conducted emissions, conducted immunity, EUT, reference ground.

This amendment refines measurement definitions and artificial network requirements essential for reliable, repeatable conducted disturbance testing in conformity assessments.

Replace the existing title by the following new title:
4 Artificial networks for AC mains and other power ports
4.1 General
Replace the existing text, including Notes 1 and 2, by the following new text and new notes:
An AN is required to provide a defined impedance at radio frequencies at the terminals of the
EUT's port under test, to isolate the test circuit from unwanted RF signals on the laboratory
AC or DC supply mains, other power source or load connected to the EUT but not subject to
testing in relation with that EUT, and to couple the disturbance voltage to the measuring
receiver.
For use with measurements on LV AC mains power ports, there are two basic types of AMN,
the V-AMN, which couples the unsymmetric voltages, and the Δ-AMN, which couples the
symmetric and the asymmetric voltages separately. Use of practical implementations of these
AMNs is not restricted to LV AC mains power ports. In principle they can be used for
measurements on any kind of power port. The user of such artificial networks is
recommended to consult the respective product standard for guidance. The information and
advice in this standard for the AMN is hence valid for use of that AMN or another AN at power
ports other
