&Nbsp&Nbsp&Nbsp&Nbsp; With the development of industry, there are more and more electronic and electrical products, and their compatibility is particularly important. Electromagnetic compatibility testing is the testing of electromagnetic compatibility. Electromagnetic compatibility (also known as EMC) refers to the ability of a device or system to operate in an electromagnetic environment in compliance with requirements without generating unbearable electromagnetic interference from any device in its environment. Therefore, EMC includes two requirements: on the one hand, it refers to the device having a certain degree of immunity to electromagnetic interference present in the environment, namely electromagnetic sensitivity; On the other hand, it refers to the fact that the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit. Let's learn electromagnetic compatibility testing projects and standards together with Baijian Electromagnetic compatibility testing range ◆ Shielding efficiency of dark rooms, shielded rooms, cabins, chassis cabinets, and shielding materials ◆ Household electrical equipment, information technology equipment, multimedia equipment audio and video equipment, ◆ Telecommunications terminal equipment, network telecommunications equipment, wireless communication equipment ◆ Aircraft electrical equipment, marine electronic equipment and systems ◆ Modules and systems of road vehicles, electrical/electronic components, rolling stock Electronic and electrical equipment for rail transit and railways ◆ Industrial, measuring, scientific, and medical equipment, control and laboratory equipment ◆ Financial electronic equipment, power electronic equipment, nuclear instrument equipment and systems ◆ Fire alarm equipment, environmental gas detection equipment, weighing display controllers ◆ Radio anechoic chamber normalized site attenuation, site voltage standing wave ratio, and field uniformity electromagnetic compatibility testing projects&Nbsp&Nbsp&Nbsp; Vibration wave/ringing wave immunity; Electrostatic discharge immunity; Electrical fast transient pulse group; Surge (impact); Immunity to conducted disturbances induced by radio frequency fields; Power frequency magnetic field immunity; Pulse magnetic field immunity; Damping oscillation magnetic field immunity; Voltage sag and disturbance power; Harmonic current emission; Radiation emission; Low frequency immunity of AC power port harmonics, inter harmonics, and power grid signals; Immunity to common mode conducted disturbances from 0Hz to 150kHz; Immunity to short-term interruptions and voltage changes; Voltage changes, conducted disturbances at telecommunications ports; DC power input port voltage sag, voltage fluctuation, and flicker; Antenna end disturbance voltage; Radio frequency electromagnetic field radiation immunity; Shielding effectiveness; Input immunity; RF common mode voltage at the antenna end; Shielding effect; Induced voltage; Transient immunity of power lines and non power lines; Power line induction; Power line contact; Radiation stray disturbance; High current injection; Superimposed AC voltage, slow drop and rise of supply voltage, and transient changes in supply voltage; Normalized field attenuation, voltage standing wave ratio, and field uniformity; Insertion loss of filters, etc. Author: Bornde Testing https://www.bilibili.com/read/cv10104491/ Source: Bilibili
