Report No.: SET2019-03397 3. 47 CFR PART 15B REQUIREMENTS 3.1 Conducted Emission 3.1.1 Requirement According to FCC section 15.107, the radio frequency voltage that is conducted back onto the AC power line on any frequency within the band 150kHz to 30MHz shall not exceed the limits in the following table, as measured using a 50µH/50Ω line impedance stabilization network (LISN). Conducted Limit (dBµV) Frequency range (MHz) Quasi-peak Average 0.15 - 0.50 66 to 56 56 to 46 0.50 - 5 56 46 5 - 30 60 50 Note: a) The limit subjects to the Class B digital device. b) The lower limit shall apply at the band edges. c) The limit decreases linearly with the logarithm of the frequency in the range 0.15 - 0.50MHz. 3.1.2 Test Description See section 2.3.1 of this report. 3.1.3 Test Result The maximum conducted interference is searched using Peak (PK), Quasi-peak (QP) and Average (AV) detectors; the emission levels more than the AV and QP limits, and that have narrow margins from the AV and QP limits will be re-measured with AV and QP detectors. Tests for both L phase and N phase lines of the power mains connected to the EUT are performed. All test modes are considered, refer to recorded points and plots below. Note: Devices subject to Part 15 must be tested for all available U.S. voltages and frequencies (such as a Nominal 120V AC,50/60Hz) for which the device is capable of operation. A device rated for 50/60 Hz operation need not be tested at both frequencies provided the radiated and line conducted emissions are the same at both frequencies. CCIC-SET/T（00） Page 11 of 18

Report No.: SET2019-03397 3.2 Radiated Emission 3.2.1 Requirement According to FCC section 15.109, the field strength of radiated emissions from unintentional radiators at a distance of 3 meters shall not exceed the following values: Frequency Field Strength Field Strength Limitation at 3m Measurement Dist range (MHz) µV/m Dist (uV/m) (dBuV/m) 0.009 - 0.490 2400/F(kHz) 300m 10000* 2400/F(kHz) 20log 2400/F(kHz) + 80 0.490 - 1.705 2400/F(kHz) 30m 100* 2400/F(kHz) 20log 2400/F(kHz) + 40 1.705 - 30.00 30 30m 100*30 20log 30 + 40 30.0 - 88.0 100 3m 100 20log 100 88.0 - 216.0 150 3m 150 20log 150 216.0 - 960.0 200 3m 200 20log 200 Above 960.0 500 3m 500 20log 500 a) As shown in FCC section 15.35(b), for frequencies above 1000MHz, the field strength limits are based on average detector. When average radiated emission measurements are specified in this part, including emission measurements below 1000MHz, there also is a limit on the radio frequency emissions, as measured using instrumentation with a peak detector function, corresponding to 20dB above the maximum permitted average limit for the frequency being investigated unless a different peak emission limit is otherwise specified in the rules. b) Test Antenna is 3m away from the EUT. Test Antenna height is varied from 1m to 4m above the ground to determine the maximum value of the field strength. c) For below 1G :QP detector RBW 120kHz ,VBW 300kHz. d) For Above 1G: PK detector RBW 1MHz,VBW 3MHz for PK value ;AV detector RBW 1MHz, VBW 10Hz for AV value. Note: 1) The tighter limit shall apply at the boundary between two frequency range. 2) Limitation expressed in dBuV/m is calculated by 20log Emission Level(uV/m). 3) If measurement is made at 3m distance, then F.S Limitation at 3m distance is adjusted by using the formula of Ld1 = Ld2 * (d2/d1)2. Example: F.S Limit at 30m distance is 30uV/m, then F.S Limitation at 3m distance is adjusted as Ld1 = L1 = 30uV/m * (10)2 = 100 * 30uV/m. CCIC-SET/T（00） Page 14 of 18

Report No.: SET2019-03397 3.2.2 Test Description See section 2.3.2 of this report. 3.2.3 Test Result The maximum radiated emission is searched using PK, QP and AV detectors; the emission levels more than the limits, and that have narrow margins from the limits will be re-measured with AV and QP detectors. Both the vertical and the horizontal polarizations of the Test Antenna are considered to perform the tests. All test modes are considered, refer to recorded points and plots below. The amplitude of spurious emissions which are attenuated more than 20 dB below the permissible value need not be reported. Note: All radiated emission tests were performed in X, Y, Z axis direction, and only the worst axis test condition was recorded in this test report. CCIC-SET/T（00） Page 15 of 18
