2.4 Test Procedure The EUT and simulators are connected to the main power through a line impedance stabilization network (L.LS.N.). This provides a 50 ohm /50uH coupling impedance for the measuring equipment. The peripheral devices are also connected to the main power through a LISN that provides a 50ohm/50uH coupling impedance with 50ohm termination. (Please refers to the block diagram of the test setup and photographs.) Both sides of A.C. line are checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipment and all of the interface cables must be changed according to ANSI C63.4 /1992 on conducted measurement. The bandwidth of the field strength meter (R & S Test Receiver ESCS 30) is set at IkHz. 25 Test Results The conducted cmission from the EUT is measured and shown in attachment 1 of test report. The acceptance criterion was met and the EUT passed the test.

Distance refers to the distance in meters between the measuring instrument antenna and the closed point of any part of the device or system. 3. RF Line Voltage (dBuV) = 20 log RF Line Voltage (uV) 3.4 Test Procedure The EUT and its simulators are placed on a turn table which is 0.8 meter above ground. The turn table can rotate 360 degrees to determine the position of the maximum emission level. The EUT was positioned such that the distance from antenna to the EUT was 10 meters . The antenna can move up and down between 1 meter and 4 meters to find out the maximum emission level. Both horizontal and vertical polarization of the antenna are set on measurement. In order to find the maximum emission, all of the interface cables must be manipulated according to ANSI C63.4 /1992 on radiated measurement. The bandwidth below 1Ghz setting on the field strength meter (R&S Test Receiver ESCS 30 ) is 120 KHz. 3.5 Test Results The radiated emission from the EUT is measured and shown in attachment 1 of test report. The acceptance criterion was met and the EUT passed the test.
