CONTINUOUS DISTURBANCE VOLTAGE, MAIN TERMINAL : Frequency range 0.15 MHz to 30 MHz 4.1 Operating environment Temperature : 22.0 °C Relative Humidity : 32.0 % 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 Upload & Download mode, play mode 4.4 Test instrument Instrument Model No Serial No. Makers Next cal.date Used Test receiver ESCS30 100022 R&S 2004. 06. 16 x ESH3-Z5 100029 R&S 2004. 11. 11 x L.I.S.N.
