Therefore, sufficient tests were made to demonstrate that the alternative site produces results that correlate with the ones of tests made in an open field based on KDB 937606. Radiated emission measurements are performed at 3m distance with the broadband antenna (Double ridged guide antenna). The antenna is positioned both the horizontal and vertical planes of polarization and height is varied 1m to 4m and stopped at height producing the maximum emission. The EUT is Placed on a turntable, which is 0.8m/1.5m above ground plane. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level. The test results represent the worst case emission for each emission with manipulating the EUT, support equipment, interconnecting cables and varying the mode of operation. Sufficient time for the EUT, support equipment, and test equipment are allowed in order for them to warm up to their normal operating condition. - Test configuration TÜV SÜD Japan Ltd. Page 55 of 74

Test method : ANSI C63.10 Frequency range : 0.15 MHz to 30 MHz Test place : 3m Semi-anechoic chamber EUT was placed on : FRP table / (W) 2.0 × (D) 1.0 × (H) 0.8 m Vertical Metal Reference Plane : (W) 2.0 × (H) 2.0 m, 0.4 m away from EUT Test receiver setting - Detector : Quasi-peak, Average - Bandwidth : 9 kHz EUT and peripherals are connected to 50Ω/50 μH Line Impedance Stabilization Network (LISN) which are connected to reference ground plane, and are placed 80cm away from EUT. Excess of AC power cable is bundled in center. LISN for peripheral is terminated in 50Ω. EUT operating mode is selected to emit the maximum noise. Overall frequency range is investigated with spectrum analyzer using peak detector. Maximum emission configuration is determined by manipulating the EUT, peripherals, interconnecting cables. Then, emission measurements are performed with test receiver in above setting to each current-carrying conductor of the mains port. Sufficient time for EUT, peripherals and test equipment is provided in order for them to warm up to their normal operating condition. If the average limit is met when using a quasi-peak detector receiver, the EUT shall be deemed to meet both limits. - Test configuration 4.8.2 Calculation method Emission level = Reading + (LISN. Factor + Cable system loss) Margin = Limit – Emission level Example: Limit @ 0.403 MHz: 57.8 dBμV(Quasi-peak) : 47.8 dBμV(Average) (Quasi peak) Reading = 22.7 dBμV c.f. = 10.4 dB Emission level = 22.7 + 10.4 = 33.1 dBμV Margin = 57.8 – 33.1 = 24.7 dB (Average) Reading = 6.5 dBμV c.f. = 10.4 dB Emission level = 6.5 + 10.4 = 16.9 dBμV Margin = 47.8 – 16.9 = 30.9 dB TÜV SÜD Japan Ltd.
