FACILITIES AND ACCREDITATIONS 3.1 FACILITIES The semi anechoic chamber and conducted measurement facility used to collect the radiated and conducted test data are located at the 42, Yurim-ro, 154beon-gil, Cheoin-gu, Yongin-si, Gyeonggi-do, Korea 449-935. The site is constructed in conformance with the requirements. - Semi anechoic chamber registration Number: 596748 3.2 EQUIPMENT Radiated emissions are measured with one or more of the following types of antennas: loop, tuned dipole, bi-conical, log periodic, bi-log, and/or ridged waveguide horn. Spectrum analyzers with pre-selectors and peak, quasi-peak detectors are used to perform radiated measurements. Conducted emissions are measured with Line Impedance Stabilization Networks and EMI Test Receivers. Calibrated wideband preamplifiers, coaxial cables, and coaxial attenuators are also used for making measurements. All receiving equipment conforms to CISPR Publication 16-1, “Radio Interference Measuring Apparatus and Measurement Methods.” FCC ID : DEO-MT-IMMO-03 DEMC1408-03296 Report No.: DRTFCC1409-1248 TRF-RF-204(01)110221 Page 7 / 13 Copyright ○ C 2014, DT&C Co., Ltd. 4.
