Report No.: DRTFCC1807-0186 FCC ID: SS4EF401 ▣ Test Procedure Below 1GHz Above 1GHz ▣ Test Procedure 1. The EUT is placed on a non-conductive table. For emission measurements at or below 1 GHz, the table height is 80 cm. For emission measurements above 1 GHz, the table height is 1.5 m. 2. The turn table shall be rotated for 360 degrees to determine the position of maximum emission level. 3. EUT is set 1m or 3 m away from the receiving antenna, which is varied from 1m to 4 m to find out the highest emissions. 4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance. 5. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 6. Repeat above procedures until the measurements for all frequencies are complete. Radiated spurious emission measured using following Measurement Procedure of KDB789033 D02v02r01 ► General Requirements for Unwanted Emissions Measurements The following requirements apply to all unwanted emissions measurements, both in and outside of the restricted bands: ▪ EUT Duty Cycle (1) The EUT shall be configured or modified to transmit continuously except as stated in (ii), below. The intent is to test at 100 percent duty cycle; however a small reduction in duty cycle (to no lower than 98 percent) is permitted if required by the EUT for amplitude control purposes. Manufacturers are expected to provide software to the test lab to permit such continuous operation. (2) If continuous transmission (or at least 98 percent duty cycle) cannot be achieved due to hardware limitations of the EUT (e.g., overheating), the following additions to the measurement and reporting procedures are required: • The EUT shall be configured to operate at the maximum achievable duty cycle. • Measure the duty cycle, x, of the transmitter output signal. • Adjustments to measurement procedures (e.g., increasing test time and number of traces averaged) shall be performed as described in the procedures below. • The test report shall include the following additional information: ◦ The reason for the duty cycle limitation. ◦ The duty cycle achieved for testing and the associated transmit duration and interval between transmissions. ◦ The sweep time and the amount of time used for trace stabilization during max-hold measurements for peak emission measurements. (3) Reduction of the measured emission amplitude levels to account for operational duty factor is not permitted. Compliance is based on emission levels occurring during transmission - not on an average across on and off times of the transmitter.

Report No.: DRTFCC1807-0186 FCC ID: SS4EF401 ► Measurements below 1000 MHz a) Follow the requirements in section II.G.3, “General Requirements for Unwanted Emissions Measurements”. b) Compliance shall be demonstrated using CISPR quasi-peak detection; however, peak detection is permitted as an alternative to quasi-peak detection. ► Measurements Above 1000 MHz (Peak) a) Follow the requirements in section II.G.3, “General Requirements for Unwanted Emissions Measurements”. b) Peak emission levels are measured by setting the analyzer as follows: (i) RBW = 1 MHz. (ii) VBW ≥ 3 MHz. (iii) Detector = Peak. (iv) Sweep time = Auto. (v) Trace mode = Max hold. (vi) Allow sweeps to continue until the trace stabilizes. Note that if the transmission is not continuous, the time required for the trace to stabilize will increase by a factor of approximately 1/x, where x is the duty cycle. For example, at 50 percent duty cycle, the measurement time will increase by a factor of two relative to measurement time for continuous transmission. ► Measurements Above 1000 MHz (Method AD) (i) RBW = 1 MHz. (ii) VBW ≥ 3 MHz. (iii) Detector = RMS, if span / (# of points in sweep) ≤ RBW / 2. Satisfying this condition may require increasing the number of points in the sweep or reducing the span. If the condition is not satisfied, the detector mode shall be set to peak. (iv) Averaging type = power (i.e., RMS) • As an alternative, the detector and averaging type may be set for linear voltage averaging. Some analyzers require linear display mode in order to use linear voltage averaging. Log or dB averaging shall not be used. (v) Sweep time = Auto. (vi) Perform a trace average of at least 100 traces if the transmission is continuous. If the transmission is not continuous, the number of traces shall be increased by a factor of 1/x, where x is the duty cycle. For example, with 50 percent duty cycle, at least 200 traces shall be averaged. (vii) If tests are performed with the EUT transmitting at a duty cycle less than 98 percent, a correction factor shall be added to the measurement results prior to comparing to the emission limit in order to compute the emission level that would have been measured had the test been performed at 100 percent duty cycle. The correction factor is computed as follows: • If power averaging (RMS) mode was used in step (iv) above, the correction factor is 10 log(1/x), where x is the duty cycle. For example, if the transmit duty cycle was 50 percent, then 3 dB must be added to the measured emission levels. • If linear voltage averaging mode was used in step (iv) above, the correction factor is 20 log (1/x), where x is the duty cycle. For example, if the transmit duty cycle was 50 percent, then 6 dB must be added to the measured emission levels. • If a specific emission is demonstrated to be continuous (100 percent duty cycle) rather than turning on and off with the transmit cycle, no duty cycle correction is required for that emission.

Report No.: DRTFCC1807-0186 FCC ID: SS4EF401 8.7 AC Conducted Emissions ▣ Test Requirements and limit, §15.207 For an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 150 kHz to 30 MHz, shall not exceed the limits in the following table, as measured using a 50 μH/50 ohms line impedance stabilization network (LISN). Conducted Limit (dBuV) Frequency Range (MHz) Quasi-Peak Average 0.15 ~ 0.5 66 to 56 * 56 to 46 * 0.5 ~ 5 56 46 5 ~ 30 60 50 * Decreases with the logarithm of the frequency Compliance with this provision shall be based on the measurement of the radio frequency voltage between each power line (LINE and NEUTRAL) and ground at the power terminals. ▣ Test Configuration See test photographs for the actual connections between EUT and support equipment. ▣ Test Procedure Conducted emissions from the EUT were measured according to the ANSI C63.10-2013. 1. The test procedure is performed in a 6.5 m × 3.5 m × 3.5 m (L × W × H) shielded room. The EUT along with its peripherals were placed on a 1.0 m (W) × 1.5 m (L) and 0.8 m in height wooden table and the EUT was adjusted to maintain a 0.4 meter space from a vertical reference plane. 2. The EUT was connected to power mains through a line impedance stabilization network (LISN) which provides 50 ohm coupling impedance for measuring instrument and the chassis ground was bounded to the horizontal ground plane of shielded room. 3. All peripherals were connected to the second LISN and the chassis ground also bounded to the horizontal ground plane of shielded room. 4.The excess power cable between the EUT and the LISN was bundled. The power cables of peripherals were unbundled. All connecting cables of EUT and peripherals were moved to find the maximum emission. ▣ Measurement Data: Comply Note 1: See next pages for actual measured spectrum plots and data for worst case result.

Report No.: DRTFCC1807-0186 FCC ID: SS4EF401 APPENDIX II Duty Cycle Information ▣ Test Procedure Duty Cycle [X = On Time / ( On + Off time )] is measured using Measurement Procedure of KDB789033 D02v02r01 1. Set the center frequency of the spectrum analyzer to the center frequency of the transmission. 2. Set RBW ≥ EBW if possible; otherwise, set RBW to the largest available value. 3. Set VBW ≥ RBW. Set detector = peak. 4. Note : The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T, where T is defined in section II.B.1.a), and the number of sweep points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to 3 MHz, then the zero-span method of measuring duty cycle shall not be used if T ≤ 16.7 microseconds.) T : The minimum transmission duration over which the transmitter is on and is transmitting at its maximum power control level for the tested mode of operation. (T = On time of the above table since the EUT operates with above fixed Duty Cycle and it is the minimum On time) ▣ Test Results: Duty cycle Maximum Achievable Duty Cycle Tested Duty Cycle (x) = On / (On+Off) Mode Data Frequency Correction 50/T Rate Factor [kHz] [MHz] On Time (On+Off) Time x [dB] [ms] [ms] 802.11a 6Mbps 5180 1.040 1.238 84.01 0.76 48.08 802.11ac MCS0 5180 0.975 1.173 83.12 0.81 51.28 (VHT20) 802.11ac MCS0 5190 0.492 0.691 71.20 1.48 101.63 (VHT40) 802.11ac MCS0 5210 0.248 0.448 55.36 2.57 201.61 (VHT80) TRF-RF-233(03)161101 Prohibits the copying and re-issue of this report without DT&C approval.
