CONTINUOUS DISTURBANCE VOLTAGE, MAIN TERMINAL : Frequency range 0.15 MHz to 30 MHz 4.1 Operating environment Temperature : 19.0 Relative Humidity : 58.0 % 4.2 Test set-up and test procedures The mains terminal disturbance voltage was measured with the equipment under test(EUT) in a shield room. The EUT was connected to an artificial mains network(LISN) placed on the floor. The EUT was placed on non-metallic table 0.4m above the metallic, grounded floor. The distance to other metallic surface was at least 0.8m. Amplitude measurements were performed with a quasi-peak detector and an average detector. 4.3 Operation Conditions Up & download mode, play mode 4.4 Test instrument Instrument Model No Serial No. Makers Next cal.date Used Test receiver ESCS30 100021 R&S 2004. 1. 24 ESH3-Z5 827246/008 R&S 2004. 3. 19 L.I.S.N.

RADIATED DISTURBANCE : 30MHz – 1000MHz 5.1 Operating environment Temperature : 22.0 Relative Humidity : 55.0 % 5.2 Test set-up The frequency range investigated was 30 MHz to 1000 MHz. All readings are quasi-peak unless stated otherwise. The half-wave dipole antenna was tuned to the frequency found during Preliminary radiated measurements. The EUT, support equipment and Interconnecting cables were re-configured to the set-up to the producing the Maximum emission for the frequency and were placed on top of a 0.8 meter High non-metallic 1 X 1.5 meter table. The EUT, support equipment, and interconnecting cables were re-arranged and manipulated to maximize each EME emission. The turntable containing the system was rotated the antenna height was varied 1 to 4 meters and stopped at the azimuth or height producing the maximum emission. And this device(EUT) was tested in 3 orthogonal planes. The antenna measured both horizontal and vertical polarization. <General test set-up for radiated emissions> 5.3 Operation Conditions Up & download mode, play mode ELECTROMA…
