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, Republic 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 February 26, 2026(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.˒ The report shall not be (partly) reproduced except in full without approval of the laboratory.

The radio frequency voltage or powers generated within the equipment and appearing on a spurious frequency shall be checked at the equipment output terminals when properly loaded with a suitable artificial antenna. Curves or equivalent data shall show the magnitude of each harmonic and other spurious emission that can be detected when the equipment is operated under the conditions specified in §2.1049 as appropriate. The magnitude of spurious emissions which are attenuated more than 20 dB below the permissible value need not be specified. §90.219 Use of signal boosters. (e) Device Specifications. In addition to the general rules for equipment certification in §90.203(a)(2) and part 2, subpart J of this chapter, a signal booster must also meet the rules in this paragraph. (3) Spurious emissions from a signal booster must not exceed −13 dBm within any 100 kHz measurement bandwidth. Test Procedures: Measurements were in accordance with the test methods section 4.7 of KDB 935210 D05 v01r04. Spurious emissions shall be measured using a single test signal sequentially tuned to frequencies within each authorized frequency band of operation. Intermodulation products shall be measured using two CW signals with all available channel spacing with the center between these channels being equal to the center frequency f 0 as determined from Out-of-band rejection test. 4.7.2 Out-of-band/out-of-block emissions conducted measurements a) Connect a signal generator to the input of the EUT. b) If the signal generator is not capable of producing two independent modulated carriers simultaneously, then two discrete signal generators can be connected, with an appropriate combining network to support the two- signal test. c) Configure the two signal generators to produce CW on frequencies spaced consistent with f 0 , with amplitude levels set to just below the AGC threshold. d) Connect a spectrum analyzer to the EUT output. e) Set the span to 100 kHz. f) Set RBW = 300 Hz with VBW ͖ 3 × RBW. g) Set the detector to power averaging (rms). h) Place a marker on highest intermodulation product amplitude. i) Capture the plot for inclusion in the test report. j) Repeat steps c) to h) with the composite input power level set to 3 dB above the AGC threshold. k) Repeat steps b) to i) for all operational bands. The report shall not be (partly) reproduced except in full without approval of the laboratory. Report No. HCT-RF-2605-FC013 F-TP22-03 (Rev. 06) Page 77 of 91 4.7.3 EUT spurious emissions conducted measurements a) Connect a signal generator to the input of the EUT. b) Configure the signal generator to produce a CW signal. c) Set the frequency of the CW signal to the center channel of the EUT passband. d) Set the output power level so that the resultant signal is just below the AGC threshold. e) Connect a spectrum analyzer to the output of the EUT, using appropriate attenuation as necessary. f) Set the RBW = 100 kHz. (i.e., for 30 MHz to 1 GHz PLMRS and/or PSRS booster devices) g) Set the VBW = 3 × RBW. h) Set the Sweep time = auto-couple. i) Set the detector to PEAK. j) Set the spectrum analyzer start frequency to 30 MHz (or the lowest radio frequency signal generated in the EUT, without going below 9 kHz if the EUT has additional internal clock frequencies), and the stop frequency to 10 times the highest allowable frequency of the EUT passband. k) Select MAX HOLD, and use the marker peak function to find the highest emission(s) outside the passband. (This could be either at a frequency lesser or greater than the passband frequencies.) l) Capture a plot for inclusion in the test report. m) Repeat steps c) to l) for each authorized frequency band/block of operation.
