TEST INFORMATION FCC Rule Parts CFR 47 Part 2, Part 27 Measurement Standards KDB 935210 D05 v01r04, KDB 971168 D01 v03r01, 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-2209-FC001 F-TP22-03 (Rev. 04) Page 6 of 79 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, ᄲRadio Interference Measuring Apparatus and Measurement Methods.ᄶ Report No. HCT-RF-2209-FC001 F-TP22-03 (Rev. 04) Page 7 of 79 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 27 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, §27.50(j)(2), §27.50(j)(4) Compliant Out-of-band/out-of-block emissions and spurious emissions §2.1051, §27.53(l)(1) Compliant Spurious emissions radiated §2.1053, §27.53(l)(1) Compliant Frequency Stability §2.1055 §27.54 Compliant Report No. HCT-RF-2209-FC001 F-TP22-03 (Rev. 04) Page 8 of 79 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 C-Band 5G NR 20 MHz 5G NR 40 MHz 5G NR 60 MHz 5G NR 80 MHz 5G NR 100 MHz The tests results included actual loss value for attenuator and cable combination as shown …
