1. Attestation of Test Results
1.1. Description of EUT
 The Equipment Under Test (EUT) was a Desktop computer with Bluetooth, Bluetooth Low Energy and
 802.11 a/b/g/n/ac capabilities in the 2.4 GHz and 5.0 GHz bands.


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:                  30 May 2019 to 07 June 2019

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.

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

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%          ±1.96 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.

Operating Modes

The EUT was tested in the following operating mode(s):
    •    Continuously transmitting at maximum power on the middle channels as required.
    •    The EUT was tested in the following operating mode(s): Pre-scans were performed with the EUT
         transmitting in Bluetooth BR, Bluetooth LE, 2.4 GHz WLAN and 5.0 GHz WLAN modes
         individually or simultaneously. The worst case mode was found to be with Bluetooth BR
         transmitting. Final measurements were performed in this configuration.

Configuration and Peripherals

The EUT was tested in the following configuration(s):
    •    Final measurements were performed with the EUT configured to transmit at maximum output
         power using Bluetooth BR on channel 38.
    •    Pre-scan plots for all other configurations are archived on the 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
         ‘MAC_scripts_310119.zip’.
    •    The EUT was powered from a 120 VAC 60 Hz single phase mains supply unless otherwise stated.
    •    Both HDMI ports were terminated into powered monitors. The Ethernet ports and all USB ports
         were also terminated.

 Test Sample Serial Numbers:          C02YF00CMFLF


 FCC Reference:                       Part 15.207
 Test Method Used:                    ANSI C63.10 Section 6.2 / FCC KDB 174176 and notes below

Environmental Conditions:

 Temperature (°C):                    22 to 23
 Relative Humidity (%):               52 to 53

Note(s):

 1. The EUT was connected to a 120 VAC 60 Hz single phase supply via a LISN.
 2. In accordance with FCC KDB 174176 Q4, tests were also 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 and markers placed on the highest live and neutral measured levels. Final
    measurements were performed on the marker frequencies and the results entered into the tables
    below.
 5. Pre-scans were performed with the EUT transmitting on the middle channels of Bluetooth BR,
    Bluetooth LE, 2.4 GHz WLAN and 5 GHz WLAN modes individually, along with each Bluetooth
    technology transmitting in combination with WLAN transmitting in both bands.
 6. The worst case mode observed during prescans was found to be the EUT with Vendor 2 radio
    modules when transmitting Bluetooth BR only. The final measurements were performed in this mode
    only. Pre-scan result plots for Vendor 1 modules / other modes are archived on the UL VS LTD IT
    server and available for inspection if required.
