description
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.
