According to the requirements in Section 13.1.4.1 of ANSI C63.10-2013. Conducted emissions from the EUT measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-Peak and average detector mode. 2.3.2 Radiated Emissions Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above 1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane. The turn table shall rotate 360 degrees to determine the position of maximum emission level. EUT is set 3m away from the receiving antenna which varied from 1m to 4m to find out the highest emission. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of EUT was fixed in a particular direction according to the requirements in Section 13.1.4.1 of ANSI C63.10-2013.

Radiated Emission Test Page 17 of 88 Report No.: E01A22110261F00101 7.1 Measurement Procedure 1. The testing follows the guidelines in Spurious Radiated Emissions of ANSI C63.10-2013. 2. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above 1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane. 3. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 4. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower (From 1m to 4m) and turntable (from 0 degree to 360 degree) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level to comply with the guidelines. 5. Set to the maximum power setting and enable the EUT transmit continuously. 6. Final measurement (Above 1GHz): The frequency range will be divided into different sub ranges depending of the frequency range of the used horn antenna. The EMI Receiver set to peak and average mode and a resolution bandwidth of 1MHz. The measurement will be performed in horizontal and vertical polarization of the measuring antenna and while rotating the EUT in its vertical axis in the range of 0 degree to 360 degree in order to have the antenna inside the cone of radiation. 7. Test Procedure of measurement (For Above 1GHz): 1) Monitor the frequency range at horizontal polarization and move the antenna over all sides of the EUT(if necessary move the EUT to another orthogonal axis). 2) Change the antenna polarization and repeat 1) with vertical polarization. 3) Make a hardcopy of the spectrum. 4) Measure the frequency of the detected emissions with a lower span and resolution bandwidth to increase the accuracy and note the frequency value. 5) Change the analyser mode to Clear/ Write and found the cone of emission. 6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m and the antenna will be still inside the cone of emission. 7) Measure the level of the detected frequency with the correct resolution bandwidth, with the antenna polarization and azimuth and the peak and average detector, which causes the maximum emission. 8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the antenna beamwidth.

The dwell time is calculated by: Dwell time = time slot length * hop rate / number of hopping channels * 31.6s with: - hop rate = 1600 * 1/s for DH1 packets = 1600 s-1 - hop rate = 1600/3 * 1/s for DH3 packets = 533.33 s-1 - number of hopping channels = 79 - 31.6 s = 0.4 seconds multiplied by the number of hopping channels = 0.4 s * 79 The highest value of the dwell time is reported. 11.2 Test SET-UP (Block Diagram of Configuration) EUT Spectrum Analyzer 11.3 Measurement Equipment Used: EQUIPMENT TYPE Spectrum Analyzer Coaxial Cable Antenna Connector MFR Rohde & Schwarz Gigalink Microwave ARTHUR-YANG MODEL NUMBER FSV40 ZT40 2244-N1TG1 SERIAL NUMBER US40240623 19022092 N/A CALIBRATED UNTIL 2022-11-12 2022-11-12 2022-11-12 Calibration interval 1 year 1 year 1 year Remark: The temporary antenna connector is soldered on the PCB board in order to perform conducted tests and this temporary antenna connector is listed in the equipment list. 11.4 Test Requirements / Limits FCC Part 15, Subpart C, §15.247 (a) (1) (iii) Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 channels. The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Since the Bluetooth technology uses 79 channels this period is calculated to be 31.6seconds. Refer to attached data chart. TRF No.: 01-R001-3A-BT Global Testing , Great Quality.

Band EDGE test Page 58 of 88 Report No.: E01A22110261F00101 13.1Measurement Procedure For Conducted Test 1. The transmitter output is connected to a spectrum analyzer. The resolution bandwidth is set to 100KHz. The video bandwidth is set to 300KHz. 2. The spectrum from 30MHz to 26 GHz is investigated with the transmitter set to the lowest, middle, and highest channels. EMI Test Receiver Setting Attenuation Auto RBW 100KHz VBW 300KHz Detector Peak Trace Max hold For Radiated emission Test The EUT was placed on a styrofoam table which is 1.5m above ground plane. The measurement procedure at the ban edges was simplified by performing the measurement in just one plot. Both, the in-band-emission and the unwanted emission were be encompassed by the span. After trace stabilization, the maximum peak was be determined by a peak detector and the value was marked by an appropriate limit line. The second limit line, which is 20dB below the first, marks the limit for the emissions in the unrestricted band. A maximum-peak-detector marks the highest emission in the unrestricted band next to the band edge. The measurements were performed at the lower end of the 2.4GHz band. Use the following spectrum analyzer settings: For Restricted Band, When spectrum scanned above 1GHz setting resolution bandwidth 1MHz, video bandwidth 3MHz: EMI Test Receiver Setting Attenuation Auto RBW 1MHz VBW 3MHz Detector Peak Trace Max hold For Non-Restricted Band, When spectrum scanned above 1GHz setting resolution bandwidth 100KHz, video bandwidth 300KHz: EMI Test Receiver Attenuation RBW VBW Detector Trace Setting Auto 100KHz 300KHz Peak Max hold TRF No.: 01-R001-3A-BT Global Testing , Great Quality.
