Electromagnetic compatibility (EMC) is essential for ensuring that electrical and electronic equipment continues to operate correctly when exposed to electromagnetic disturbances. IEC 61000-4-3 provides a standardized method for evaluating the immunity of equipment to radiated radio-frequency electromagnetic fields. This comprehensive course is designed to provide learners with both theoretical understanding and practical knowledge of radiated RF immunity testing according to IEC 61000-4-3.
Throughout the course, you will learn the fundamental principles of radiated RF immunity testing, understand the requirements of the standard, and explore how a complete EMC test setup is designed and operated. The course covers important test equipment such as RF signal generators, power amplifiers, antennas, field sensors, monitoring systems, and test-site equipment. You will also learn how to establish the required electromagnetic field, perform field calibration and uniformity verification, select appropriate test frequencies and test levels, apply modulation, configure the Equipment Under Test (EUT), and conduct the immunity test in a controlled laboratory environment.
