EN 55022 is a European standard for the measurement of electromagnetic compatibility (EMC) in electronic equipment. The standard specifies the requirements for radiated and conducted emissions, as well as the limits for radiated and conducted immunity. Shielding effectiveness testing is an important aspect of EN 55022, as it is used to evaluate the ability of electronic equipment to withstand and reduce the effects of electromagnetic interference.
Electromagnetic compatibility is the ability of electronic equipment to function satisfactorily in the presence of electromagnetic fields and electromagnetic interference. EMC includes both emissions and immunity, and EN 55022 provides requirements and limits for both aspects of EMC.
EN 55022 provides limits for the radiated and conducted emissions and immunity, which are designed to ensure that electronic equipment does not interfere with other electronic systems and that it is protected from harmful electromagnetic fields. The limits are specified in terms of field strength or power density, and are defined for different frequency ranges.
Emissions are the unwanted electromagnetic energy that is generated by electronic equipment. The standard defines the limits for the amount of electromagnetic energy that can be transmitted from electronic equipment, in terms of field strength or power density. This is important because electronic equipment that transmits high levels of electromagnetic energy can cause interference with other electronic systems, leading to degradation of performance or even damage.
Immunity is the ability of electronic equipment to withstand external electromagnetic fields without degradation of performance or damage. The standard provides limits for the level of electromagnetic interference that electronic equipment must be able to withstand, in terms of field strength or power density. This is important because electronic equipment that is susceptible to electromagnetic interference can be affected by other electronic systems, leading to degradation of performance or even damage.
EN 55022 provides requirements for the measurement of radiated and conducted emissions and immunity. The standard defines the test methods, test conditions, and measurement procedures that must be followed in order to comply with the requirements. The results of the testing provide important information that can be used to design and improve the electromagnetic compatibility of electronic systems.
