Conducted Emission
Conducted Emission Test
The conducted emission test is applied to measure the electromagnetic interference emitted by electrical and electronic devices into the environment through power or signal lines. This test is one of the fundamental components of the device’s electromagnetic compatibility assessment.
Purpose of the Test
The objective is to determine whether the device generates electromagnetic interference (EMI) at a level that may affect other electronic systems in the environment through conduction paths such as the power cable.
This test is carried out within the framework of international EMC standards such as TS EN 55011 and TS EN 55032.
Who Needs It?
- Electronic device manufacturers
- Industrial automation system manufacturers
- Medical device developers
- Consumer electronics product suppliers
Test Process
The conducted emission test is generally performed by measuring the device connected to a transmission line within a specified frequency range, usually 150 kHz – 30 MHz, using spectrum analyzers. In the laboratory environment, precise results are obtained using a LISN (Line Impedance Stabilization Network).
Compliance with Standards
All emission tests are carried out in accordance with European and global regulations. Within this scope, the requirements for conformity certificates such as CE marking, FCC and CISPR are fulfilled.
