EQUIPMENT UNDER TEST DESCRIPTION OF EUT The EUT is a portable computing device with 802.11 a/b/g/n/ac 2x2 WLAN, Bluetooth, Bluetooth LE, WCDMA and LTE radios. MAXIMUM OUTPUT POWER ERP/EIRP LIMIT FCC: §2.1046, §22.913, §24.232 IC: RSS132§5.4; RSS133§6.4 EIRP/ERP TEST PROCEDURE ANSI C63.26:2015 KDB 971168 D01 Section 5.6 ERP/EIRP = PMeas + GT − LC where: ERP/EIRP = effective or equivalent radiated power, respectively (expressed in the same units as PMeas, typically dBW or dBm); PMeas = measured transmitter output power or PSD, in dBm or dBW; GT = gain of the transmitting antenna, in dBd (ERP) or dBi (EIRP); LC = signal attenuation in the connecting cable between the transmitter and antenna, in dB. For devices utilizing multiple antennas, KDB 662911 provides guidance for determining the effective array transmit antenna gain term to be used in the above equation. The transmitter has a maximum average conducted and ERP / EIRP output powers as follows: WCDMA MODE RSS 132 Band 5 Frequency range Conducted (Average) Antenna Gain Limit EIRP 99% BW Emission Modulation (MHz) (dBm) (dBi) (W) (dBm) (W) (kHz) Designator REL 99 24.0 23.19 0.209 4134.8 4M13F9W 826.4-846.6 -0.80 11.5 HSDPA 23.9 23.12 0.205 4130.7 4M13F9W Part 22 Band 5 Frequency range Conducted (Average) Antenna Gain Limit ERP 99% BW Emission Modulation (MHz) (dBm) (dBi) (W) (dBm) (W) (kHz) Designator REL 99 24.0 21.04 0.127 4134.8 4M13F9W 826.4-846.6 -0.80 7.0 HSDPA 23.9 20.97 0.125 4130.7 4M13F9W Part 24 / RSS 133 Band 2 Frequency range Conducted (Average) Antenna Gain Limit EIRP 99% BW Emission Modulation (MHz) (dBm) (dBi) (W) (dBm) (W) (kHz) Designator REL 99 24.0 25.60 0.363 4136.5 4M14F9W 1852.4-1907.6 1.60 2.0 HSDPA 23.9 25.50 0.355 4146.6 4M15F9W Page 8 of 35 UL VERIFICATION SERVICES INC.

REPORT NO: 12802195-E6V2 DATE: SEPTEMBER 06, 2019 FCC ID: C3K1876 IC: 3048A-1876 SOFTWARE AND FIRMWARE The EUT firmware installed during testing was version BSP 6300. MAXIMUM ANTENNA GAIN Antenna Gain Frequency Range (MHz) (dBi) 824 - 849 -0.8 1850 - 1910 1.6 WORST-CASE CONFIGURATION AND MODE The worst-case is EUT on the highest power. Based on average conducted output power measurement investigations, the following modes should be considered as worst-case scenario for all other measurements. Worst-case modes: • WCDMA REL 99 • WCDMA HSDPA The EUT was investigated in different orthogonal orientations X/Y/Z, and 45 degree angle when attached with the keyboard, with/without AC/DC adapter, cables and accessories. It was determined that 45 degree angle orientation when attached with the keyboard was the worst-case orientation for 800/1900MHz bands with AC/DC adapter, cables and accessories. All radios that can be transmitted simultaneously have been evaluated for radiated for all possible combinations of transmission and found to be in compliance. For simultaneous transmission of any BT/BLE/WLAN (2.4GHz) and WWAN bands or WLAN 5GHz and WWAN bands, investigation has been performed and no noticeable new emission was found.

RF OUTPUT POWER VERIFICATION WCDMA TEST PROCEDURE The transmitter output was connected to the input terminal of Directional Coupler via calibrated coaxial cable. The output coupling terminal of the Directional Coupler was directly connected to a spectrum analyzer while the output through terminal connected to the communication test set via calibrated coaxial cable. The output power was measured with the spectrum analyzer at the low, middle and high channel in each band. • Set the spectrum analyzer span wide enough or greater than the modulated signal BW. • Set a spectrum analyzer at peak detection mode with VBW ≥ RBW.≥ 26dB BW, typically 5MHz. • Set a marker to point the corresponding peak value. REL 99 The following tests were completed according to the test requirements outlined in section 5.2 of the 3GPP TS34.121-1 specification. The DUT supports power Class 3, which has a nominal maximum output power of 24 dBm (+1.7/-3.7).

In lieu of meeting the above stability values, the test report may show that the frequency stability is sufficient to ensure that the occupied bandwidth stays within each of the sub-bands (see Section 5.1) when tested to the temperature and supply voltage variations specified in RSS-Gen. RSS133§6.3 The carrier frequency shall not depart from the reference frequency, in excess of ±2.5 ppm for mobile stations and±1.0 ppm for base stations. In lieu of meeting the above stability values, the test report may show that the frequency stability is sufficient to ensure that the emission bandwidth stays within the operating frequency block when tested to the temperature and supply voltage variations specified in RSS-Gen. TEST PROCEDURE Use CMW 500 with Frequency Error measurement capability. • Temp. = −30°C to +50°C • Voltage = (85% - 115%) Low voltage, 6.4VDC, Normal, 7.6VDC and High voltage, 8.7VDC. End Voltage, 5.1VDC. Frequency Stability vs Temperature: The EUT is place inside a temperature chamber. The temperature is set to 20ºC and allowed to stabilize. After sufficient soak time, the transmitting frequency error is measured. The temperature is increased by 10 degrees, allowed to stabilize and soak, and then the measurement is repeated. This is repeated until +50ºC is reached. Frequency Stability vs Voltage: The peak frequency error is recorded (worst-case). RESULTS See the following pages.
