When it comes to the design and operation of electrical and electronic equipment, Electromagnetic Compatibility (EMC) is a critical consideration. Ensuring that devices function correctly in their electromagnetic environment without facing unacceptable interference is of utmost importance. To address these concerns, several standards have been devised, with CISPR (Comite International Special des Perturbations Radioelectriques (CISPR), 16-1 playing a key role. It is a part of the broader CISPR 16 series, which safeguards radio reception on devices operating between 9kHz to 400 GHz from electromagnetic interference caused by other devices.

What is CISPR 16-1?
CISPR 16-1, a small part of the larger EMC global and regional standards, is a set of technical standards developed by CISPR. The CISPR 16 series is divided into several parts, with Part 1 (CISPR 16-1) including six parts that define specific standards for the measuring apparatus and equipment utilized to conduct the required EMC tests.
Following are the sub-parts under CISPR 16-1, each addressing specific aspects of EMC measurement equipment.
- CISPR 16-1-1: This standard specifies the performance characteristics and calibration requirements for EMC measuring instruments, such as spectrum analyzers, antennas, and other measurement instruments. It covers aspects such as frequency range, sensitivity, selectivity, and dynamic range, polarization characteristics, and gain and pattern of the antenna, among others. Compliance with this standard ensures that the instruments can accurately detect and measure electromagnetic disturbances.
- CISPR 16-1-2: The standard defines the characteristics and performance of equipment when measuring for radio disturbance voltages and currents, including current probes, voltage probes, and Line Impedance Stabilization Networks (LISNs). These devices must meet stringent requirements to accurately capture interference signals conducted along power lines or other conductors.
- CISPR 16-1-3: The CISPR 16-1-3 standard, part of the broader CISPR 16 series, focuses on the specifications for radio disturbance and immunity measuring equipment, particularly ancillary equipment for disturbance power. It sets the standards for the apparatus used to measure disturbance power in devices, ensuring accuracy and consistency in testing.
- CISPR 16-1-4: The standard outlines definite requirements for characterizing antennas and test sites used in EMC testing. It includes guidelines for calibrating antenna parameters to ensure accurate measurements. The standard also mentions the methods for assessing the characteristics of test sites, including the evaluation of the electromagnetic environment, measurement of background noise levels, and determination of the site's reflection coefficient.
- CISPR 16-1-5: The standard outlines requirements for choosing and assessing calibration and reference test sites. It includes evaluating the site's electromagnetic environment, checking the background noise levels, and measuring how it reflects signals. It also details the equipment and procedures needed to carry out these assessments.
- CISPR 16-1-6: It specifies guidelines for calibrating antennas used in EMC testing. Compliance with these standards ensures antennas are accurately calibrated for measuring radio disturbances and immunity.
Needless to say, compliance with CISPR 16-1 not only ensures product quality and reliability but also enables easy to international markets by meeting regulatory requirements. For any firm involved in the design, testing, or certification of electronic devices, understanding and adhering to the EMC requirements in CISPR 16-1 is highly critical.
