The measurement are performed in the shielded room which dimension is 3.0*7.0*2.5(m). The EUT was placed on a non conductive table which is 1.0*1.5(m), 80 cm above an earthed ground plane and is kept at least 1m from any other earthed ground plane except the rear of table top being removed 40 cm from a vertical conducting plane. Power to the EUT was provided through the LISN(3725/2,EMCO) which has the Impedance vs Frequency Characteristic in accordance with the Fig.1 Impedance Characteristic of LISN. Peripheral equipment required to provide a functional system(support equipment) for EUT testing was powered through another LISN(NSLK8128,Schwarzbeck). Power to the LISN was filtered to eliminate ambient signal interference. A coaxial type connector which provides a 50 Ohm terminating impedance was provided for the test instrument. The excess length of the power cord was wrapped in the two non metallic pegs attached to the top of the LISN. The two pegs are 9 cm high, approximately 2.0 cm in diameter and that are spaced 6cm on the center apart. 1.6 Test Facility Location: Korea EMC Labor…
