Radiated Immunity:Radiated Immunity is a characteristic of a device to withstand external electromagnetic interference and continue to operate normally as intended. A device can malfunction when subjected to Stray EMI radiations generated by nearby devices thus it must remain immune to such radiations to function normally. For example, a laptop connected to a local Wi-Fi should function smoothly i...read more

EFT Immunity is the ability of an electronic/electrical device to withstand the interference of electrical fast transients (EFTs). EFTs are generally high-frequency pulses caused by sparking or arcing. The sparks occur during circuit connection or disconnection from a power supply, switchgear operation, or when lines touch each other. The EFT pulse can be filtered easily but it becomes rather diff...read more

Understanding EMI, EMC, EMC testing, and EMC standardsAn electrical and electronic product usually emits some amount of unwanted electromagnetic energy (called electromagnetic interference (EMI)) during its operation. The EMI of a product may affect the performance of or sometimes damage the nearby electronic device(s).Electromagnetic Compatibility (EMC) is the capability/ability of an electrical ...read more

Conducted immunity refers to the device’s ability to resist unwanted RF voltages and currents that get coupled to the external wires and cables. These coupled RF voltages and currents are nothing but unwanted noise that could hamper the intended functions of the device.What is Conducted Immunity Testing?Conducted immunity testing is used to determine whether the Equipment Under Test (EUT) ha...read more

Apr 12, 2023

Conducted susceptibility and immunity are essentially two important aspects of EMC Testing. Conducted susceptibility refers to the ability of electronic equipment to withstand electromagnetic interference that is coupled through the power or signal lines whereas Conducted Immunity, on the other hand, refers to the ability of electronic equipment to resist external electromagnetic interference that...read more
