Report No. 00 - 341 – 046 4 Page of 11 . CONDUCTED EMISSION MEASUREMENT (Section 18.307) 1. Test Procedure The EUT was installed with fluorescent lamp in accordance with the manufacturer’s instruction and operated in a manner that is the representative of the typical usage for equipment. Conducted emission measurements on the EUT were performed by "Conducted Powerline Measurement" procedure as per MP-5. The EUT w as set up on a w ooden table 0.4 meters height, 1.0 by 1.5 meters in size, placed in the shielded enclosed with a side of wall of which constituted a vertical conducting surface of 2.2 m x 3.1 m in size to maintain 0.8 meters from the rear of EUT LISN's(Line Impedance Stabilization Network, EMCO, 3825/2, 50 ohm / 50 ∝H) were installed and electrically boned to the conducting ground plane. The EUT was connected to the LISN. One of two 50 ohm output terminals of the LISN was connected to the Spectrum Analyzer(HP, 8566B, 10 kHz to 22 GHz) with the Quasi-Peak Adapter (HP, 85650A, 10 kHz to 1.0 GHz) and the other was terminated in 50 ohms. Measurements w ere again performed after interchanging such a connection oppositely. The frequency range from 450 kHz to 30 MHz was examined and the peak values that are within 6 dB of the limit would be compared to quasi-peak values using the Quasi-Peak instrument (ROHDE & SCHWARZ, ESH3, 9 kHz to 30 MHz : Detector Function CISPR Quasi-Peak) or HP Quasi-Peak adapter(85650A, 10 kHz to 1.0 GHz) The voltage developed across the 50 ohms port in LISN was measured by the Spectrum Analyzer and graphed by the Plotter(HP, 7470A). The 6 dB bandwidth of the Spectrum Analyzer and Quasi-Peak Adapter was set to 9 kHz with no post detector video filter. The position of connecting cables of the EUT was changed to find the w orst case configuration during measurements. The maximum emission level from the EUT occurred in such configuration as shown in the following photograph. Ref. Report No. 00 - 341 – 046 5 Page of 11 2. Photograph for the test configuration 3. Sample Calculation The emission level measured in decibels above one microvolt (dB∂) was converted into microvolt (∂) as show n in following sample calculation. For example : Measured Value at 0.55 MHz 41.5 dB∂ + Cable Losses * 0.0 dB −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−− = Conducted Emission 41.5 dB∂ ( = 118.9 ∂ ) * In case of RG214/ RF cable 15 Ft, the loss is about 0.17 dB at the frequency of 30 MHz which is negligible.
