What is EN 55016-2-1:2020

EN55016-2-1:2020 is a professional technical standard that defines the methods and limits for measuring the conducted emission of radio frequency (RF) devices. It specifically focuses on the measurement of RF disturbances generated by information technology equipment (ITE) and sound and television broadcast receivers. This standard provides guidelines for manufacturers, testing laboratories, and regulatory authorities to ensure compliance with electromagnetic compatibility (EMC) requirements.

Scope of EN55016-2-1:2020

The scope of EN55016-2-1:2020 covers the measurement of broadband conducted disturbances in the frequency range of 9 kHz to 150 kHz. It applies to both intentional radiators, which are devices purposely designed to emit RF energy, and unintentional radiators, which are devices that incidentally generate RF energy as a byproduct of their operation. The standard sets out specific test methodologies and specifies the limits for conducted emissions based on the intended use and environment of the equipment being tested.

Testing and Compliance

To ensure compliance with EN55016-2-1:2020, manufacturers need to perform conducted emission tests on their products. These tests involve connecting the device under test (DUT) to a power supply and measuring the RF signals it emits through its power input leads. The measurement setup must follow the guidelines outlined in the standard to ensure accurate and repeatable results.

The conducted emission limits specified in EN55016-2-1:2020 depend on the intended application of the equipment. For example, different limits apply to residential environments compared to industrial or commercial environments. Manufacturers must ensure that their products meet the applicable limits in order to obtain the necessary certifications and approvals for market access.

Conclusion

EN55016-2-1:2020 is a crucial technical standard in the field of electromagnetic compatibility. It provides guidelines for measuring and limiting conducted emissions from RF devices, ensuring that they do not interfere with the proper functioning of other electronic equipment. Compliance with this standard is necessary for manufacturers to meet regulatory requirements and gain market access. By following the testing methods and limits outlined in EN55016-2-1:2020, manufacturers can ensure their products are safe, reliable, and electromagnetically compatible.
