Immunity to Conducted Disturbances
Immunity to Conducted Disturbances Induced by RF Fields
IEC/EN 61000-4-3 Radio Frequency Electromagnetic Field Immunity Test is applied to evaluate the resistance level of electronic and electrical devices against environmental electromagnetic fields. This test measures the ability of products to maintain their performance when exposed to high-frequency electromagnetic fields.
Test Structure and Features
- Radio frequency signals are applied in the range of 150 kHz – 80 MHz
- Direct injection is applied to transmission lines using a Coupling/Decoupling Network (CDN)
- The typical test level is 3 Vrms as a modulated RF signal
- It is performed in accordance with the IEC/EN 61000-4-6 standard
What Is Its Purpose?
The purpose of this test is to measure the resistance of devices against disturbances received through transmission lines due to radio frequency fields. Immunity against such disturbances is critically important for products such as industrial automation systems, communication devices and medical equipment. Test results determine whether the device can operate stably in an electromagnetic environment.
Compliance with Standards
Our tests are carried out in accordance with the IEC 61000-4-6 standard, and test levels, frequency steps and modulation types are set according to the conditions specified in the standard. The equipment used is regularly calibrated, and the conductivity level of the test environment is kept under control.
Why Is It Important?
Conducted disturbances caused by radio frequency sources pose a serious threat, especially for devices operating in dense industrial areas. Through this test, it is evaluated whether the device is affected by undesired effects such as instability, data corruption or reset while operating in disturbed environments. This test, which is an important requirement for CE marking and other conformity certificates, ensures the documentation of product reliability.
