Surge Generators & EFT Generators. EMC Partner. The IMU Series Immunity Test System from EMC Partner is the most flexible multi function generator covering up to 10 IEC/EN compliance standards in one compact test system (EFT, Surge, Ringwave, Voltage Dips/Interruptions, Magnetic Fields & more).

To the right is an example of an EFT pulse. For this particular pulse, the voltage risetime is approx 5ns with a pulse width of approximately 50ns. There are other profiles of EFT pulses for different standards but this is the most common for 61000-4-4 compliance.
