TEST SYSTEM CONFIGURATION 3.1 Operation Environment Temperature Humidity Pressure OATS : 15°C 46 % 1011 hPa Shield room : 24°C 39 % 1011 hPa Test site These testing were performed following locations; OATS (3m) : Radiated emission Shield room : Conducted emission 3.2 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMI. The factors contributing to uncertainties are test receiver, Cable Loss, antenna factor calibration, Antenna directivity, antenna factor Variation with height, antenna phase center variation, antenna Frequency interpolation, measurement distance variation, Site imperfection, mismatching, and system repeatability. Based on NIS 80, 81, the measurement uncertainty level with a 95% confidence level was applied. 3.3 Sample calculation Conducted emission The field strength is calculated by adding the LISN factor, cable loss to the measured reading. The sample calculation is as follows : FS = MR + LF + CL MR = Meter Reading LF = LISN Factor 82-1, JEIL-RI, YANGJI-MYUN, YONGIN-CITY, KYUNGGI-DO, KOREA TEL: 82 31 336 9919 FAX : 82 31 336 4767 This test report shall not be reproduced except in full, Without the written approval. Report No.: EMC-FCC-0107 Page : 6 of 20 CL = Cable Loss If MR is 30dB, LISN Factor 1dB, CL 1dB The result (FS) is 30 + 1 + 1 = 32dBuV Radiated emission The field strength is calculated adding the antenna Factor, cable loss and, Antenna pad adding, subtracting the amplifier gain from the measured reading. The sample calculation is as follows : FS = MR + AF + CL + AT –AG MR = Meter Reading AF = Antenna Factor CL = Cable Loss AP = Antenna Pad AG=Amplifier Gain If MR is 30dB, AF 12dB, CL 5dB, AP 10dB, AG 35dB The result (MR) is 30 + 12 + 5 + 10 –35 = 22dBuV/m 82-1, JEIL-RI, YANGJI-MYUN, YONGIN-CITY, KYUNGGI-DO, KOREA TEL: 82 31 336 9919 FAX : 82 31 336 4767 This test report shall not be reproduced except in full, Without the written approval.
