RADIATED EMISSIONS AND BAND EDGES 3.1 Applicable Standard FCC 15.235(a) The field strength of any emission within this band shall not exceed 10,000 microvolis/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. FCC 15.235(b) The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodulated carrier or to the general limits in §15.209, whichever permits the higher emission levels. The field strength of any emissions removed by more than 10 kHz from the band edges shall not exceed the general radiated emission limits in §15.209. All signals exceeding 20 microvolts/meter at 3 meters shall be reported in the application for certification. 3.2 Test Setup (1) Radiated Emission Test—Up Frequency Below 30MHz RX Antenna _ EUT euenTaile ‘ 1T m IO.B m Ground Plane | Receiver (2) Radiated Emission Test—Up Frequency 30MHz~1GHz Ground Plane Receiver i _ 3.3 EMI Test Receiver Setup The system was investigated from 30 MHz to 1000 MHz. During the radiated emission test, the EMI test receiver was set with the following configurations: Frequency Range RBW Video B/W IF BAV Detector S0MHz — 1000 MHz 100 kHz 300 kHz 120 kHz oP

Page 9 of 19 Report No.: HUAK180723597E 3.4 Test Procedure 1. Below 1GHz measurement the EUT is placed on turntable which is 0.8m above ground plane. And above 1GHz measurement EUT was placed on low permittivity and low tangent turn table which is 1.5m above ground plane. 2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level. 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m 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. 7. The test frequency range from 9KHz to 25GHz per FCC PART 15.33(a). Note: For battery operated equipment, the equipment tests shall be performed using a new battery.

Page 12 of 19 Report No.: HUAK180723597E 4 20dB EMISSION BANDWIDTH 4.1 Applicable Standard Intentional radiators operating under the alternative provisions to the general emission limits, as contained in § 15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. 4.2 Test Procedure 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect it to measurement instrument. Then set it to any one convenient frequency within its operating range. Set a reference level on the measuring instrument equal to the highest peak value. 3. Measure the frequency difference of two frequencies that were attenuated 20 dB from the reference level. Record the frequency difference as the emission bandwidth. 4. Repeat above procedures until all frequencies measured were complete. 4.3 Test Result

The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. Antenna Connector Construction The EUT has a helical antenna arrangement, which was permanently attached and the antenna gain is 20 dBi; fulfill the requirement of this section.
