Is EFT/B sufficient to reproduce malfunctions of EUTs?

― Current immunity testing for transient phenomena defined by international standards describes a test method that applies a waveform simulating typical electromagnetic noise that occurs in nature, such as ESD, EFT/B and lightning surge.
― However, in the actual field, we can be affected by various noises beyond those phenomena described in the standard.
― In case of the EFT/B test, it provides only limited power line noise test and sometimes is difficult to reproduce design failures.
― NoiseKen’s INS (Impulse Noise Simulator) provides a unique test method that covers the noise phenomena which cannot be reproduced by the EFT/B test defined by the international standard IEC 61000-4-4.

A simulator to reproduce fast rise-up noises which are generated when switching ON / OFF electric current on the inductive load. It can be used for performance evaluation of electronic equipment upon reproduction of line noises which are intruded to the power supply lines or induced noises onto the telecommunication lines.


Advantages of Impulse Noise Test
