Abstract :
VCCI* Technical Sub-committee has investigated the dispersion of radiated emission measurement results . It was confirmed that one of the main cause of the dispersion of radiated emission measurement results was the difference of the power line-to-ground impedance of the power supply for the equipment under test (EUT). For the improvement of the dispersion, VCCI manufactured the experimental VHF-LISN (very high frequency-line impedance stabilization network). And we confirmed the validity of this VHF-LISN.
