DESCRIPTION OF TEST 2.1 Measurement of Conducted Emission The test procedure was in accordance with ANSI C63.4-2003, Clause 7 a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being connected to the power mains through a line impedance stabilization network (LISN). If the EUT is connected to the PC through USB, the AC power-line adapter of the PC is directly connected to a line impedance stabilization network (LISN). Other support units were connected to the power mains through another LISN. The two LISNs provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument. b. Both conducted lines are measured in Quasi…
