TBCDNE-M2

Coupling Decoupling Networks Emission

The TBCDNE-M2 Coupling / Decoupling Network – Emission is an EMC accessory designed to support conducted emission measurements. It enables accurate coupling of RF noise from the Equipment Under Test (EUT) onto power lines while simultaneously decoupling and isolating the test setup from external mains influences. This ensures that measured emissions reflect the EUT’s characteristics rather than interference introduced from the power source or environment, improving the integrity of conducted emission test results.
