FACILITIES AND ACCREDITATIONS 2.1. FACILITIES The SAC(Semi-Anechoic Chamber) and conducted measurement facility used to collect the radiated data are located at the 74, Seoicheon-ro 578beon-gil, Majang-myeon, Icheon-si, Gyeonggi-do, 17383, Rep. of KOREA. The site is constructed in conformance with the requirements of ANSI C63.4 (Version: 2014) and CISPR Publication 22. Detailed description of test facility was submitted to the Commission and accepted dated April 02, 2018 (Registration Number: KR0032). 2.2. EQUIPMENT Radiated emissions are measured with one or more of the following types of Linearly polarized antennas: tuned dipole, bi- conical, log periodic, bi-log, and/or ridged waveguide, horn. Spectrum analyzers with pre-selectors and quasi-peak detectors are used to perform radiated measurements. Calibrated wideband preamplifiers, coaxial cables, and coaxial attenuators are also used for making measurements. All receiving equipment conforms to CISPR Publication 16-1, ˑRadio Interference Measuring Apparatus and Measurement Methods.˒ F-TP22-03 (Rev. 03) Page 8 of 80 Report No. HCT-RF-2011-FC018-R1 3.
