20 MHz-80 MHz Low Frequency Radiated Immunity Testing

Radio frequency electromagnetic field radiated immunity, also known as radiated sensitivity or immunity, R/S, is one of the most basic electromagnetic compatibility immunity testing items. It refers to the ability of various devices, equipment, or systems to resist radiation in the presence of a radiated electromagnetic field. The higher the sensitivity, the lower the immunity. For example, electromagnetic fields generated by radio stations, television stations, fixed or mobile radio transmitters, and various industrial radiation sources typically have a measurement frequency range of 80 MHz to 6 GHz.

For products such as electric bicycles, electric scooters, and industrial trucks, the lower frequency limit of the measurement range is reduced from the conventional standard of 80 MHz to 20 MHz, and the field strength increases to a maximum of 30 V/m. Electric bicycles, electric scooters, and industrial trucks operating in this electromagnetic field will be affected by it, potentially impacting the normal operation of the equipment.

China's JJR organization has a professional testing laboratory with complete qualifications, capable of providing one-stop radiated immunity testing and certification services.
