Electromagnetic Susceptibility (EMS)

Electromagnetic Susceptibility (EMS) refers to how sensitive an electronic device or system is to electromagnetic interference (EMI) from external sources like radio waves, electrical equipment, or wireless signals. When a device has high EMS, these external signals can cause it to malfunction, produce errors, or behave unpredictably. EMS is an important factor in designing and testing electronic equipment to ensure it operates reliably in environments with various electromagnetic signals. Essentially, EMS measures how much external electromagnetic energy can affect the proper functioning of a device.
