CISPR 15 edition 9 offers different methods for the measurement of radio disturbance characteristics of electrical lighting equipment. One of these is the CDNE method. This method specifies the use of a coupling / decoupling network for emission measurement (CDNE) to measure disturbance voltages in the 30 to 300 MHz frequency range. This method enables EUTs to be connected directly to the CDNE, allowing a single conducted emission measurement to replace a lengthy radiated emission test. The TESEQ CDNEs are compliant with the actual versions of CSIPR 16-1-2, CISPR 16-2-1 and CISPR 15 edition 9. Using a CDNE instead of CDN offers improved measurement reproducibility due to standard’s requirements for more restrictive limits of asymmetrical impedance, phase angle, symmetrical impedance and internal attenuation. CISPR 15 edition 9 requires the termination of the mains supply cable of the EUT with a CDNE positioned on the reference-ground plane for the OATS, SAC or FAR measurement method. The receiver port of the CDNE is terminated with a 50 Ω impedance.
