EN 55035 EMC Immunity Test of Multimedia Devices
The EN 55035 standard is a crucial part of the Electromagnetic Compatibility (EMC) suite, designed to ensure that multimedia devices function correctly in their electromagnetic environment. This test evaluates how well electronic equipment can withstand interference from external electromagnetic fields without malfunctioning or causing harmful interference.
The EN 55035 standard is particularly important for devices such as TVs, monitors, audio systems, and other consumer electronics that are used daily by millions of people worldwide. Non-compliance with these standards could lead to malfunctions in electronic equipment, potential safety hazards, and even health risks if the interference affects sensitive medical devices.
The test aims to ensure that multimedia devices can operate correctly under conditions where they are exposed to electromagnetic fields generated by other devices. This includes both conducted and radiated emissions immunity tests which are critical for preventing interference in communication channels between electronic equipment.
Conducted Immunity (Ci) testing measures the ability of a device to function properly when subjected to conducted electromagnetic disturbance signals over specific frequency bands. Radiated Immunity (Ir) testing assesses the robustness of devices against radiated electromagnetic fields that could cause interference or malfunction.
In practice, this involves placing the multimedia device under test in an environment where controlled electromagnetic disturbances are generated and measuring its response. The test setup typically includes a屏蔽模式
