FCC ID: ZNFX420AS8 Report No.: HCT—EM—1904—FCO26 F@«C HICTGC.LTA 3. DESCRIPTION OF TEST 3.1 Measurement of Conducted Emission The test procedure was in accordance with ANSI C63.4—2014, Clause 7.3 a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being connected to the power mains through a line impedance stabilization network (LISN). If the EUT is connected to the PC through USB, the AC power—line adapter of the PC is directly connected to a line impedance stabilization network (LISN). Other support units were connected to the power mains through another LISN. The two LISNs provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument. b. Both conducted lines are measured in Quasi—Peak and Average mode, including the worst—case data points for each tested configuration. c. The frequency range from 150 kHz to 30 MHz was searched. [ Conducted Emission Limits ] Frequency Resolution Bandwidth Quasi—Peak Average (MHz) (kHz) (dB(uV)) (dB(uV)) 0.15 to 0.5 9 66 to 56* 56 to 46* 0.5 to 5 9 56 46 5 to 30 9 60 50 *Decreases with the logarithm of the frequency.

FCC ID: ZNFX420AS8 Report No.: HCT—EM—1904—FCO26 F@«C HICTGC.LTA 3.2 Measurement of Radiated Emission The test procedure was in accordance with ANSI C63.4—2014, Clause 8.3 a. The EUT was placed on the top of a turn table 0.8 meters above the ground at a semi—anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 3 m away from the interference—receiving antenna, which was mounted on the top of a variable—height antenna tower. c. The antenna height is varied from 1 m to 4 m above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 m to 4 m and the turn table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test—receiver system was set to Quasi—Peak detect function and specified bandwidth with maximum hold mode when the test frequency is below 1 GHz. f. The test—receiver system was set to Peak and Average detect function and specified bandwidth with maximum hold mode when the test frequency is above 1 GHz. g. Place the measurement antenna away from each area of the EUT determined to be a source of emissions at the specified measurement distance, while keeping the measurement antenna aimed at the source of emissions at each frequency of significant emissions, with polarization oriented for maximum response.(1 GHz to 40 GHz) [ Radiated Emission Limits ] Frequency Antenna Distance Field Strength Quasi—Peak (MHz) (m) (uV/m) (dB(uV)/m) 30 to 88 3 100 40.0 88 to 216 3 150 43.5 216 to 960 3 200 46.0 Above 960 3 500 54.0 Frequency Antenna Distance Peak Average (MHz) (m) (dB(uV)/m) (dB(uV)/m) Above 1 000 3 74 54 F—TP22—03 (Rev.00) 9 / 22 HCT CO.,LTD.
