New TESEQ CDNE Coupling/Decoupling Network for Emission Testing
Teseq, has developed a new coupling/decoupling (CDNE) network for emissions testing.
The publication of EN 55015, based on CISPR 15 A1 Ed 7, has introduced an independent method of measurement of radio disturbance characteristics of electrical lighting equipment. This method specifies the use of a coupling/decoupling network (CDN) as defined in IEC 61000-4-6 for emission measurement in the frequency range 30 to 300 MHz.
An aThe result describes a specific coupling/decoupling network for emissions (CDNE). In addition to closer tolerances for the asymmetrical impedance, the phase angle, symmetrical impedance and the internal attenuation are also defined.
Teseq’s CDNE series fulfils these new requirements and offers improved reproducibility for current EN 55015 measurements.
