- Designed for conducted emission test setups.
- Couples RF noise from the EUT onto the test line.
- Decouples mains interference from the measurement.
- Improves accuracy and repeatability of emission measurements.
- Rugged, reliable construction for lab and field use.
- Compatible with standard conducted emission measurement systems.
TBCDNE-M3
Coupling Decoupling Networks Emission
The TBCDNE-M3 Coupling / Decoupling Network – Emission is an EMC accessory designed to support conducted emission measurements by providing a controlled path to couple noise from the Equipment Under Test (EUT) onto power or signal lines while isolating interference from external mains sources. This ensures that the measured emissions reflect only the EUT’s characteristics, improving the accuracy and repeatability of conducted emission testing.
