3. Test Standards Test Standard : FCC PART 15 This Standard sets out the regulations under which an intentional, unintentional, or incidental radiator may be operated without an individual license. It also contains the technical specifications, administrative requirements and other conditions relating to the marketing of Part 15 devices. Test Method : ANSI C 63.10 (2013) This standard sets forth uniform methods of measurement of radio-frequency (RF) signals and noise emitted from both unintentional and intentional emitters of RF energy in the frequency range 9 kHz to 40 GHz. Methods for the measurement of radiated and AC power-line conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods cover measurement of certain decides that deliberately radiate energy, such as intentional emitters, but does not cover licensed transmitters. This standard is not intended for certification/approval of avionic equipment or for industrial, scientific, and medical (ISM) equipment These method apply to the measurement of individual units or systems comprised of multiple units Summary of Test Results Applied Satandard : 47 CFR Part 15, Subpart C Standard Test Type Result Remark Limit 15.203 Antenna Requirement Pass See Appendix 2 2.1049 20 ㏈ Bandwidth Pass Meet the requirement 15.207 AC Power Conducted Emission Pass Meet the requirement 15.209 Radiated Emission Pass Meet the requirement Report Number : ESTRFC1901-004 EST-P25-IO2-F04 (2016.01.01) Page 5 of 17

5. 20dB bandwidth 5.1 Test Procedure a. Span = approximately 2 to 3 times the 20 ㏈ bandwidth, RBW = greater than 1 % of the 20 ㏈ bandwidth, VBW = RBW, Sweep = auto, Detector = peak, Trace = max hold. b. The marker-to-peak function to set the mark to the peak of the emission. Use the marker-delta function to measure 20 ㏈ down one side of the emission. Reset the function, and move the marker to the other side of the emission, until it is (as close as possible to) even with the reference marker level. The marker-delta reading at this point is 20 ㏈ bandwidth of the emission. 5.2 Test Setup 5.3 Limit None; for reporting purposed only Report Number : ESTRFC1901-004 EST-P25-IO2-F04 (2016.01.01) Page 8 of 17

5. Measurement of radiated disturbance The EUT was placed on the top of a rotating table 0.8 m above the ground at a 3 m Open test site. The table was rotated 360 ° to determine the position of the highest radiation.Then antenna is a loop antenna is fixed at one meter above the ground to determine the maximum value of the field strength. Both parallel and perpendicular of the antenna are set to make the measurement. For each suspected emission, the EUT was arranged to its worst case and then the table was turned from 0 degrees to 360 ° to find the maximum reading. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. 5.1 Radiated emission limits, general requirements Except as provided elsewhere in this Subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in the following table: Frequency Field Strength(microvolt/meter) Distance(meter) (MHz) 0.009-0.490 2400/F(KHz) 300 0.490-1.705 24000/F(KHz) 30 1.705-30 30 30 30-88 100** 3 88-216 150** 3 216-960 200** 3 Above 960 500 3 * dBuV/m=20*log(uV/m) * Distance factor=40dB / decade(15.31(f)) 5.2 Measurement equipments Next Equipment Name Type Manufacturer Serial No. Calibration date TEST Receiver ESCI7 ROHDE & SCHWARZ 100916 22-Oct-19 Logbicon Antenna VULB 9168 SCHWARZBECK 193 15-Oct-20 Turn Table DT3000-2t Innco System GmbH N/A - Antenna Mast MA4000-EP Innco System GmbH N/A - Antenna Master & CO2000/641 CO2000-P Innco System GmbH - Turn table controller /28051111/L Loop Antenna HFH2-Z2 ROHDE & SCHWARZ 100188 30-Apr-20 5.3 Environmental Condition Test Place 10 m Semi-anechoic chamber Temperature (°C) : 23.1 ℃ Humidity (%) : 47.5 % R.H.
