Full title and description

Specification for radio disturbance and immunity measuring apparatus and methods — Part 1-1: Radio disturbance and immunity measuring apparatus — Measuring apparatus (CISPR 16-1-1:2019). The document specifies characteristics and performance requirements for equipment used to measure radio disturbance (EMI) and related measuring apparatus operating in the 9 kHz to 18 GHz range, and includes requirements for specialized equipment for discontinuous disturbance measurements.

Abstract

This standard (Edition 5.0, 2019) is a basic CISPR/IEC EMC publication that defines performance, accuracy and testing/validation requirements for EMI receivers, spectrum analyzers and discontinuous disturbance analysers (e.g., click analyzers). It covers detector response types (quasi‑peak, peak, average, RMS‑average), key receiver characteristics, validation and calibration procedures (including Annex J), and guidance on use of spectrum analyzers and APD/measurement functions where applicable.

Scope

Covers specification of measuring apparatus used for the measurement of radio disturbance voltages, currents and fields in the frequency range 9 kHz to 18 GHz. The scope includes fundamental performance parameters for measuring receivers and spectrum analyzers, requirements for detectors and discontinuous disturbance analysers, and normative requirements for verification, calibration and validation of measuring equipment. It is intended as a basic EMC publication to be used by product committees to determine applicability for specific product tests.

Key topics and requirements

• Frequency range of applicability: 9 kHz to 18 GHz.
• Performance characteristics for measuring receivers and spectrum analyzers (input impedance, selectivity, bandwidth, tuning tolerance, rejection ratios, overload behaviour).
• Detector types and response requirements: quasi‑peak, peak, average and RMS‑average detectors and their pulse/continuous response characteristics.
• Discontinuous disturbance analysers (click analyzers): fundamental characteristics and validation/test methods for transient/disturbance capture.
• Calibration, verification and validation procedures for measuring apparatus (Annex J and other normative guidance), including test methods for pulse generators and nanosecond pulse measurement techniques.
• Guidance on use of spectrum analyzers for compliance measurements and references to related parts of CISPR 16 for ancillary equipment and test sites.

These topics and specific requirements are defined and expanded in the clauses and annexes of CISPR 16-1-1:2019.

Typical use and users

Used by EMC test laboratories, product test engineers, instrument manufacturers, conformity assessment bodies, and IEC/CISPR product committees. Typical uses include instrument design/validation, laboratory accreditation and setting measurement practices for product emission testing and compliance assessment.
