TEST INFORMATION FCC Rule Parts CFR 47 Part 2, Part 24 Measurement Standards KDB 935210 D05 v01r04, ANSI C63.26-2015 Test Location HCT CO., LTD. 74, Seoicheon-ro 578beon-gil, Majang-myeon, Icheon-si, Gyeonggi-do, 17383, Rep. of KOREA Report No. HCT-RF-2005-FC011 F-TP22-03 (Rev. 02) Page 6 of 125 2. 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.˒ Report No. HCT-RF-2005-FC011 F-TP22-03 (Rev. 02) Page 7 of 125 3. TEST SPECIFICATIONS 3.1. STANDARDS The following tests were conducted on a sample of the equipment for the purpose of demonstrating compliance with FCC Part 2, Part 24. Description Reference Results AGC threshold KDB 935210 D05 v01r04 3.2 Compliant Out-of-band rejection KDB 935210 D05 v01r04 3.3 Compliant Input-versus-output signal comparison §2.1049 Compliant Input/output power and amplifier/booster gain §2.1046, §24.232 Compliant Out-of-band/out-of-block emissions and spurious emissions §2.1051, §24.238 Compliant Spurious emissions radiated §2.1053 Compliant Report No. HCT-RF-2005-FC011 F-TP22-03 (Rev. 02) Page 8 of 125 3.2. ADDITIONAL DESCRIPTIONS ABOUT TEST Except for the following cases, EUT was tested under normal operating conditions. : Out-of-band rejection test requires maximum gain condition without AGC The test was generally based on the method of KDB 935210 D05 v01r04 and only followed ANSI C63.26-2015 if there was no test method in KDB standard. EUT was tested with following modulated signals provide by applicant. Band Name Tested signals PCS GSM CDMA WCDMA LTE 5 MHz LTE 10 MHz The frequency stability measurement has been omitted in accordance with section 3.7 of KDB 935210 D05 v01r04. : It can be confirmed through input-versus-output signal comparison test that EUT does not alter the input signal. The tests results included actual loss value for attenuator and cable combination as shown in the table below. : Inp…
