Full title and description

St CISPR 16-2-1-2017 — Specification for radio disturbance and immunity measuring apparatus and methods — Part 2-1: Methods of measurement of disturbances and immunity — Conducted disturbance measurements (consolidated with Amendment 1:2017).

Abstract

This standard is a basic EMC publication that specifies internationally agreed methods for measuring conducted disturbance phenomena and general disturbance-measurement techniques. It defines measurement setups, ancillary equipment (such as artificial mains networks, decoupling/coupling networks and coupling-decoupling networks for emission — CDNE), detector functions and procedures for conducted-emission testing over the specified frequency ranges, and includes the technical changes introduced by Amendment 1:2017 to the 2014 edition.

Scope

This part of CISPR 16 is a basic standard specifying methods of measurement of disturbance phenomena in general (frequency range 9 kHz to 18 GHz) and, in particular, the methods for conducted disturbance measurements (normally 9 kHz to 30 MHz). When a coupling–decoupling network for emission (CDNE) is used the frequency range of conducted disturbance measurements can be extended down to 300 Hz. The document also defines acceptable ancillary equipment, measurement conditions, and procedures needed for repeatable, comparable conducted-emission measurements.

Key topics and requirements

• Definitions of disturbance types and detector functions (peak, quasi-peak, average) and their application in measurement.
• Requirements for measuring equipment connections, reference grounding and arrangement of the equipment under test (EUT).
• Specification and use of ancillary networks: artificial mains networks (AMNs / LISNs), voltage and current probes, delta-type networks (Δ-AN), and CDNEs for low-frequency extension.
• Procedures for conducted disturbance measurements (power ports and signal ports), including asymmetric/common-mode and differential-mode measurements and considerations for signals present on telecommunication/data lines.
• Calibration, measurement uncertainty considerations, and verification/validation practices for EMC test setups.
• Guidance on measurement of continuous, intermittent and transient disturbances and on avoiding measurement artefacts from the test environment or equipment.

Typical use and users

Used by EMC test laboratories, compliance engineers, product committees, regulatory bodies and manufacturers for: designing and validating conducted-emission test setups; verifying product compliance with CISPR-derived limits; developing test programmes; and ensuring measurement repeatability and traceability in EMC testing. Test engineers consult this standard when selecting and configuring AMNs/LISNs, CDNEs and other ancillary equipment for conducted-emission testing.

Related standards

Closely related to other parts of CISPR 16 (for example CISPR 16-1-x series and CISPR 16-2-3) and to regional/adopted variants such as EN 55016 series. Also used together with product-specific CISPR series (for limits and applicability) and complementary standards for radiated measurements and immunity testing (for example IEC 61000‑4‑3 and other EMC test-method standards).

FAQ

Q: What is this standard?

A: CISPR 16-2-1 is a basic EMC standard that specifies internationally agreed methods and requirements for measuring conducted disturbance phenomena and general disturbance-measurement techniques; the 2014 edition consolidated with Amendment 1:2017 is commonly used.

Q: What does it cover?

A: It covers measurement setups, ancillary equipment (AMNs/LISNs, probes, Δ-networks, CDNE), detector functions and detailed procedures for conducting conducted-emission measurements (normally 9 kHz–30 MHz; general disturbance methods up to 18 GHz; CDNE can extend lower-frequency measurement down to 300 Hz).

Q: Who typically uses it?

A: EMC test houses and laboratory engineers, product-design and compliance teams, standards and product committees, and regulators use this standard when performing, specifying or assessing conducted-emission measurements.

Q: Is it current or superseded?

A: The authoritative base edition is the third edition published in 2014; Amendment 1 was issued in 2017 and is typically consolidated into the 2014 text (commonly referred to as 2014 + A1:2017). The consolidated publication is treated as the current basic CISPR 16-2-1 text (stability information shown by IEC indicates continued validity through the stated stability date). Always check national/adopted versions and the IEC webstore for the most recent status before use.

Q: Is it part of a series?

A: Yes — it is Part 2-1 of the CISPR 16 family (CISPR 16 is a multi-part basic EMC publication covering measuring apparatus, methods and ancillary equipment; other parts address radiated measurements, apparatus specifications and related measurement techniques).

Q: What are the key keywords?

A: EMC, conducted emissions, AMN/LISN, CDNE, delta-type network, measurement methods, detector functions, CISPR 16-2-1.
