TEST REPORT SERIAL NO: UL-RPT-RP12505086JD11A VERSION 1.0 ISSUE DATE: 16 JANUARY 2019 1. Attestation of Test Results 1.1. Description of EUT The equipment under test was a desktop computer with WLAN and BT radios. 1.2. General Information Specification Reference: 47CFR15.207 Specification Title: Code of Federal Regulations Volume 47 (Telecommunications): Part 15 Subpart C (Intentional Radiators) - Section 15.207 Location of Testing: UL VS Ltd, Unit 3 Horizon, Wade Road, Kingsland Business Park, Basingstoke, Hampshire, RG24 8AH, United Kingdom Test Dates: 04 December 2018 to 17 December 2018 1.3. Summary of Test Results FCC Reference (47CFR) Measurement Result Part 15.207 Transmitter AC Conducted Emissions Complied Note(s): 1. There are two vendors of the WiFi/Bluetooth radio modules, Vendor 1 and Vendor 2. The WiFi/Bluetooth radio modules have the same mechanical outline (i.e. the same packaging dimension and pin layout), use the same on-board antenna matching circuit, have an identical antenna structure and are built and tested to conform to the same specification and to operate within the same tolerances. Baseline testing was performed on the two vendors to determine the worst case. 1.4. Deviations from the Test Specification For the measurements contained within this test report, there were no deviations from, additions to, or exclusions from the test specification identified above.

TEST REPORT SERIAL NO: UL-RPT-RP12505086JD11A VERSION 1.0 ISSUE DATE: 16 JANUARY 2019 2. Summary of Testing 2.1. Facilities and Accreditation The test site and measurement facilities used to collect data are located at Unit 3 Horizon, Wade Road, Kingsland Business Park, Basingstoke, Hampshire, RG24 8AH, United Kingdom. UL VS LTD is accredited by UKAS. The tests reported herein have been performed in accordance with its terms of accreditation. 2.2. Methods and Procedures Reference: ANSI C63.10-2013 Title: American National Standard of Procedures for Compliance Testing of Unlicensed Wireless Devices Reference: KDB 174176 D01 Line Conducted FAQ v01r01 June 3, 2015 Title: AC Power-Line Conducted Emissions Frequently Asked Questions 2.3. Calibration and Uncertainty Measuring Instrument Calibration In accordance with UKAS requirements all the measurement equipment is on a calibration schedule. All equipment was within the calibration period on the date of testing. Measurement Uncertainty No measurement or test can ever be perfect and the imperfections give rise to error of measurement in the results. Consequently the result of a measurement is only an approximation to the value measured (the specific quantity subject to measurement) and is only complete when accompanied by a statement of the uncertainty of the approximation. The expression of uncertainty of a measurement result allows realistic comparison of results with reference values and limits given in specifications and standards. The uncertainty of the result may need to be taken into account when interpreting the measurement results. The reported expanded uncertainties below are based on a standard uncertainty multiplied by an appropriate coverage factor such that a confidence level of approximately 95% is maintained. For the purposes of this document “approximately” is interpreted as meaning “effectively” or “for most practical purposes”. Confidence Calculated Measurement Type Range Level (%) Uncertainty AC Conducted Spurious Emissions 0.15 MHz to 30 MHz 95% ±2.40 dB The methods used to calculate the above uncertainties are in line with those recommended within the various measurement specifications. Where measurement specifications do not include guidelines for the evaluation of measurement uncertainty the published guidance of the appropriate accreditation body is followed.

TEST REPORT SERIAL NO: UL-RPT-RP12505086JD11A VERSION 1.0 ISSUE DATE: 16 JANUARY 2019 Operating Modes The EUT was tested in the following operating mode(s): • Continuously transmitting at maximum power on the middle and top channels as required. • The EUT was tested in the following operating mode(s): Pre-scans were performed with the EUT transmitting in Bluetooth BDR, Bluetooth LE, 2.4 GHz WLAN and 5.0 GHz WLAN modes. The worst case mode was found to be Bluetooth BDR, 2.4 GHz WLAN and 5.0 GHz WLAN transmitting simultaneously. Final measurements were performed in this configuration. • The EUT was transmitting at full power while powered via the mains supply. Configuration and Peripherals The EUT was tested in the following configuration(s): • Final measurements were performed with the EUT configured to simultaneously transmit two signals at maximum output power. The two modes were: o Bluetooth BDR: Channel 78 / 2480 MHz o WLAN SDB: 2.4 GHz (802.11n HT20 MIMO) / Channel 6 / 2437 MHz and 5 GHz (802.11n HT40 MIMO) / U-NII Band 2C / Channel 110 / 5550 MHz Pre-scan plots for all other configurations are archived on UL VS LTD IT server and available for inspection if required. • Controlled in test mode using a software application on the EUT supplied by the customer. The application was used to enable a continuous transmission and to select the test channels as required. The customer supplied a document containing the setup instructions ‘EUT_scripts.zip’. • The EUT was powered from a 120 VAC 60 Hz single phase mains supply unless otherwise stated. • The USB ports were terminated into accessories and the Ethernet port was terminated into an Ethernet hub.

Transmitter AC Conducted Spurious Emissions Test Summary: Test Engineers: Stefan Ho, Mark Perry & Test Dates: 04 December 2018 to Matthew Botfield 17 December 2018 Test Sample Serial Numbers: C02X200XKFLX FCC Reference: Part 15.207 Test Method Used: ANSI C63.10 Section 6.2 / FCC KDB 174176 and notes below Environmental Conditions: Temperature (°C): 21 to 23 Relative Humidity (%): 40 to 46 Note(s): 1. The EUT was connected to the power supply input which was connected to a 120 VAC 60 Hz single phase supply via a LISN. 2. In accordance with FCC KDB 174176 Q4, tests were performed with a 240 VAC 60 Hz single phase supply as this was within the voltage range marked on the EUT power supply. 3. A pulse limiter was fitted between the LISN and the test receiver. 4. Pre-scans were performed with the EUT transmitting on the middle channel of Bluetooth BR, Bluetooth LE and WLAN modes. The worst case mode was found to be Bluetooth BR, SDB mode with 2.4 GHz WLAN and 5.0 GHz WLAN active simultaneously on the vendor 2 sample and final measurements were performed in this mode only. Pre-scan plots for all other modes are archived on the UL VS LTD IT server and available for inspection if required. UL VS Ltd Page 11 of 15
