What is EN 61000-4-6:1996?

EN 61000-4-6:1996 is an international standard that addresses the issue of electromagnetic compatibility (EMC). Specifically, it focuses on conducted disturbances induced by radio-frequency fields in the frequency range of 150 kHz to 80 MHz. This standard provides guidance and defines measurement techniques for assessing the immunity of electrical and electronic equipment to these disturbances.

The standard begins by outlining the scope and purpose of EN 61000-4-6:1996. It highlights the importance of ensuring that electrical and electronic systems can operate without experiencing significant interference from radio-frequency fields. The document then introduces key definitions and terminology related to conducted disturbances and immunity testing processes.

Additionally, EN 61000-4-6:1996 describes the different field sources and their respective characteristics. It covers the basic principles of disturbance testing, such as the setup and test procedures required to comply with the standard. This section also includes guidelines on specifying performance criteria and evaluating the test results.

Measurement Techniques

One crucial aspect of EN 61000-4-6:1996 is the provision of specific measurement techniques for assessing conducted disturbances induced by radio-frequency fields. The standard details how to prepare the equipment under test, including applying reference ground connections and power supply conditions. It specifies the use of artificial networks as well.

The document outlines various test levels and test methods, covering both continuous and repetitive tests. It offers clear instructions on measuring the immunity of equipment based on its intended environment. Furthermore, the standard provides guidelines for modification of the test setup, when necessary, according to the specific requirements of the system being tested.

Conclusion

EN 61000-4-6:1996 plays a vital role in ensuring the electromagnetic compatibility of electrical and electronic equipment. By addressing conducted disturbances induced by radio-frequency fields, this standard helps manufacturers and engineers assess the immunity of their systems against such interferences. Compliance with EN 61000-4-6:1996 enables the development of products that can operate reliably in today's increasingly connected world.
