The test data contained in this report pertains only to the emissions due to the EUTs Bluetooth transmitter. This Bluetooth module has been tested by a Bluetooth Qualification Lab, and we confirm the following:

A) The hopping sequence is pseudorandom B) All channels are used equally on average C) The receiver input bandwidth equals the transmit bandwidth D) The receiver hops in sequence with the transmit signal 15.247(g): In accordance with the Bluetooth Industry Standard, the system is designed to comply with all of the regulations in Section 15.247 when the transmitter is presented with a continuous data (or information) system. 15.247(h): In accordance with the Bluetooth Industry Standard, the system does not coordinate its channels selection/

hopping sequence with other frequency hopping systems for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters. 15.247(h): The EUT employs Adaptive Frequency Hopping (AFH) which identifies sources of interference namely devices operating in 802.11 WLAN and excludes them from the list of available channels. The process of re-mapping reduces the number of test channels from 79 channels to a minimum number of 20 channels. The EUT operates in two power schemes per modulation. The power schemes are Internal Pre Amplifier(iPA) and External Pre Amplifier (ePA). According to the manufacturer, models A1859 and A1960 are electrically identical. Model A1859 was used for final testing. Device Capabilities 2.2 This device contains the following capabilities:

802.11b/g/n WLAN, Bluetooth (1x, EDR, LE), NFC Note: This device is capable of operating in hopping and non-hopping mode. The EUT can hop between 79 different channels in the 2400 2483.5MHz band. 2.3 Following antenna was used for the testing. Antenna Description Table 2-1.

Frequency (GHz)Antenna Gain (dBi)2.4-11.2 2.4 Test Support Equipment Table 2-2. Test Support Equipment Used Test Configuration 2.5 The EUT was tested per the guidance of KDB 558074 D01 v04. ANSI C63.10-2013 was used to reference the appropriate EUT setup for radiated spurious emissions testing and AC line conducted testing. See Sections 3.2 for AC line conducted emissions test setups, 7.9 for radiated emissions test setups, and 7.2, 7.3, 7.4, 7.5, and 7.6 for antenna port conducted emissions test setups. Additional radiated spurious emissions measurements were performed with the EUT on a certified wireless charging pad (WCP) while operating under normal conditions in a simulated call or data transmission configuration. The worst case radiated emissions data is shown in this report. The worst case configuration was investigated for all combinations of the three materials, aluminum, ceramic, and stainless steel, and various types of wristbands, metal and non-metal wristbands. The store display sample was investigated with the three types of EUTs. The EUT was also investigated with and without wireless charger. The worst case configuration found was used for all testing. The worst case material was aluminum and the worst case accessory was metal wristband. But no significant difference was found between various types of wrist bands. The emissions below 1GHz and above 18GHz were tested with the highest transmitting power channel and the worst case configuration. The EUT was manipulated through three orthogonal planes of X-orientation (flatbed), Y-orientation

(landscape), and Z-orientation (portrait) during the testing. Only the worst case emissions were reported in this test report. The worst orientation was found to be X-orientation (flatbed). For AC line conducted and radiated test below 1GHz, following configuration were investigated and EUT powered by AC/DC was the worst case.

- EUT powered by AC/DC adaptor via USB cable with wireless charger

- EUT powered by host PC via USB cable with wireless charger

/4-DQPSK has been investigated and confirmed as not the worst case. FCC ID: BCG-A1859 Test Report S/N:

Deviation from measurement procedure.....................................None 3.2 The line-conducted facility is located inside a 7m x 3.66m x 2.7m shielded enclosure. The shielded enclosure is manufactured by AP Americas. The shielding effectiveness of the shielded room is in accordance with MIL-

Std-285 or NSA 65-6. A 1m x 1.5m wooden table 80cm high is placed 40cm away from the vertical wall and 80cm away from the sidewall of the shielded room. Two 10kHz-30MHz, 50/50H Line-Impedance Stabilization Networks (LISNs) are bonded to the shielded room floor. Power to the LISNs is filtered by external high-current high-insertion loss power line filters. The external power line filter is EPCOS 2X60A Power Line Filter (100dB Attenuation, 14kHz-18GHz) and the two EPCOs 2X48A filters (100dB Minimum Insertion Loss, 14kHz 10GHz). These filters attenuate ambient signal noise from entering the measurement lines. These filters are also bonded to the shielded enclosure. The EUT is powered from one LISN and the support equipment is powered from the second LISN. If the EUT is a DC-powered device, power will be derived from the source power supply it normally will be powered from and this supply line(s) will be connected to the second LISN. All interconnecting cables more than 1 meter were shortened to a 1 meter length by non-inductive bundling (serpentine fashion) and draped over the back edge of the test table. All cables were at least 40cm above the horizontal reference groundplane. Power cables for support equipment were routed down to the second LISN while ensuring that that cables were not draped over the second LISN. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal operating condition. The RF output of the LISN was connected to the spectrum analyzer and exploratory measurements were made to determine the frequencies producing the maximum emission from the EUT. The spectrum was scanned from 150kHz to 30MHz with a spectrum analyzer. The detector function was set to peak mode for exploratory measurements while the bandwidth of the analyzer was set to 10kHz. The EUT, support equipment, and interconnecting cables were arranged and manipulated to maximize each emission. Once the worst case emissions have been identified, the one EUT cable configuration/arrangement and mode of operation that produced these emissions is used for final measurements on the same test site. The analyzer is set to CISPR quasi-peak and average detectors with a 9kHz resolution bandwidth for final measurements. Line conducted emissions test results are shown in Section 7.12. Automated test software was used to perform the AC line conducted emissions testing. Automated measurement software utilized is Rohde &

Radiated Emissions 3.3 The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final measurements and exploratory measurements, when necessary. The measurement area is contained within the semi-

anechoic chamber which is shielded from any ambient interference. The test site inside the chamber is a 6m x 5.2m elliptical, obstruction-free area in accordance with Figure 5.7 of Clause 5 in ANSI C63.4-2014. Absorbers are arranged on the floor between the turn table and the antenna mast in such a way so as to maximize the reduction of reflections for measurements above 1GHz. An 80cm high Styrodur Plastic Test Table is placed on top of the turntable. For measurements above 1GHz, another Styrodur Plastic Test Table of 70cm height is placed on top of the test table to bring the total table height to 1.5m. For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter receive antenna height using a broadband antenna from 30MHz up to the upper frequency shown in 15.33(b)(1) depending on the highest frequency generated or used in the device or on which the device operates or tunes. For frequencies above 1GHz, linearly polarized double ridge horn antennas were used. For frequencies below 30MHz, a calibrated loop antenna was used. When exploratory measurements were necessary, they were performed at 1 meter test distance inside the semi-anechoic chamber using broadband antennas, broadband amplifiers, and spectrum analyzers to determine the frequencies and modes producing the maximum emissions. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal operating condition. The test set-up was placed on top of the 1 x 1.5 meter table. The EUT, support equipment, and interconnecting cables were arranged and manipulated to maximize each emission. Appropriate precaution was taken to ensure that all emissions from the EUT were maximized and investigated. The system configuration, mode of operation, turntable azimuth, and receive antenna height was noted for each frequency found. Final measurements were made in the semi-anechoic chamber using calibrated, linearly polarized broadband and horn antennas. The test setup was configured to the setup that produced the worst case emissions. The spectrum analyzer was set to investigate all frequencies required for testing to compare the highest radiated disturbances with respect to the specified limits. The turntable containing the EUT was rotated through 360 degrees and the height of the receive antenna was varied 1 to 4 meters and stopped at the azimuth and height producing the maximum emission. Each emission was maximized by changing the orientation of the EUT through three orthogonal planes and changing the polarity of the receive antenna, whichever produced the worst-case emissions. 3.4 The temperature is controlled within range of 15oC to 35oC. The relative humidity is controlled within range of 10% to 75%. The atmospheric pressure is monitored within the range 86-106kPa (860-1060mbar).

1) All modes of operation and data rates were investigated. The test results shown in the following sections represent the worst case emissions. 2) The analyzer plots shown in this section were all taken with a correction table loaded into the analyzer. The correction table was used to account for the losses of the cables, directional couplers, and attenuators used as part of the system to maintain a link between the call box and the EUT at all frequencies of interest. 3) All antenna port conducted emissions testing was performed on a test bench with the antenna port of the EUT connected to the spectrum analyzer through calibrated cables, attenuators, and couplers. 4) For conducted spurious emissions, automated test software was used to measure emissions and capture the corresponding plots necessary to show compliance. The measurement software utilized is PCTEST BT Auto, Version 3.3. FCC ID: BCG-A1859 Test Report S/N:

Quality Manager Page 21 of 80 7.3 Output Power Measurement 15.247 (b.1) Test Overview and Limits Measurement is made while the EUT is operating in non-hopping transmission mode. The powers shown below were measured using a spectrum analyzer with a Bluetooth signaling test set (Agilent Model: N4010A) used only to maintain a Bluetooth link with the EUT. Average power data is provided to determine the need for Bluetooth SAR testing according to KDB 447498 D01 v06. Average power measurements are performed using the analyzers burst power function with RBW = 3MHz. The burst power function triggers on a single set burst set to maximum power and measures the maximum average power on the on-time. The maximum permissible output power is 1 Watt. Test Procedure Used ANSI C63.10-2013 Section 7.8.5 Test Settings Peak Power Measurement 1. Span = approximately 5x 20dB bandwidth, centered on hopping channel 2. RBW > 20dB bandwidth of emission being measured 3. VBW RBW 4. Sweep = auto 5. Detector = peak 6. Trace mode = max hold 7. The trace was allowed to stabilize Method AVGPM-G (Average Power Measurement) Average power measurements were performed only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The power meter implemented triggering and gating capabilities which were set up such that power measurements were recorded only during the ON time of the transmitter. The trace was averaged over 100 traces to obtain the final measured average power. FCC ID: BCG-A1859 Test Report S/N:

Typically, Bluetooth 1x/EDR mode has a channel hopping rate of 1600 hops/s. Since 1x/EDR modes use 5 transmit and 1 receive slot, for a total of 6 slots, the Bluetooth transmitter is actually hopping at a rate of 1600 /

6 = 266.67 hops/s/slot o 400ms x 79 hopping channels = 31.6 sec (Time of Occupancy Limit) o Worst case BT has 266.67 hops/second (for 1x/EDR modes with DH5 operation) o 266.67 hops/second / 79 channels = 3.38 hops/second (# of hops/second on one channel) o 3.38 hops/second/channel x 31.6 seconds = 106.67 hops (# hops over a 31.6 second period) o 106.67 hops x 2.904 ms/channel = 309.77 ms (worst case dwell time for one channel in 1x/EDR modes) With AFH, the number of channels is reduced to a minimum of 20 channels and the channel hopping rate is reduced by 50% to 800 hops/s. AFH mode also uses 6 total slots so the Bluetooth transmitter hops at a rate of 800 / 6 = 133.3 hops/s/slot o 400ms x 20 hopping channels = 8 sec (Time of Occupancy Limit) o Worst case BT has 133.3 hops/second/slot (for AFH mode with DH5 operation) o 133.3 hops/s / 20 channels = 6.67 hops/second (# of hops/second on one channel) o 6.67 hops/s / channel x 8 seconds = 53.34 hops (# hops over a 8 second period) o 53.34 hops x 2.220 ms/channel = 118.41 ms (worst case dwell time for one channel in AFH mode) FCC ID: BCG-A1859 Test Report S/N:

Conducted Spurious Emissions 7.8 15.247 (d) Test Overview and Limit Conducted out-of-band spurious emissions were investigated from 30MHz up to 25GHz to include the 10th harmonic of the fundamental transmit frequency. The maximum permissible out-of-band emission level is 20 dBc. Test Procedure Used ANSI C63.10-2013 Section 7.8.8 Test Settings 1. Start frequency was set to 30MHz and stop frequency was set to 25GHz (separated into two plots per channel) 2. RBW = 1MHz* (See note below) 3. VBW = 3MHz 4. Detector = Peak 5. Trace mode = max hold 6. Sweep time = auto couple 7. The trace was allowed to stabilize Test Setup The EUT and measurement equipment were set up as shown in the diagram below. Figure 7-8. Test Instrument & Measurement Setup Test Notes Out-of-band conducted spurious emissions were investigated for all data rates and the worst case emissions were found with the EUT transmitting at 1Mbps. The display line shown in the following plots is the limit at 20dB below the fundamental emission level measured in a 100kHz bandwidth. However, the traces in the following plots are measured with a 1MHz RBW to reduce test time, so the display line may not necessarily appear to be 20dB below the level of the fundamental in a 1MHz bandwidth.
