The data found in this test report was taken with the EUT operating in Bluetooth low energy mode. According to the manufacturer, models A1891 and A1972 are electrically identical. Model A1891 was used for final testing. While in low energy mode, the Bluetooth transmitter hops pseudo-randomly between 40 channels, three of which are advertising channels. When the transmitter is hopping only between the three advertising channels, the EUT does not fall under the category of a hopper as defined in 15.247(a)(iii) which states that a frequency hopping systems in the 24002483.5 MHz band shall use at least 15 channels. As operation on only the advertising channels does not qualify the EUT as a hopper, the EUT is certified as a DTS device in this mode. The data found in this report is representative of the device when it transmits on its advertising channels. Typical Bluetooth operation is covered under the DSS report found with this application. The EUT operates in two power schemes per modulation. The power schemes are Internal Pre Amplifier (iPA) and External Pre Amplifier
(ePA). 2.2 This device contains the following capabilities:
850 WCDMA/HSPA, Multi-band LTE, 802.11b/g/n WLAN, Bluetooth (1x, EDR, LE), NFC 2.3 Following antenna gain was used for the testing. Antenna Description Device Capabilities 2.4 Test Support Table 2-1. Antenna Peak Gain Table 2-2. Test Support Equipment Used FCC ID: BCG-A1891 Test Report S/N:

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, 3.3 for radiated emissions test setups, and 7.2, 7.3, 7.4, 7.5, and 7.6 for antenna port conducted emissions test setups. This device supports wireless charging capability and, thus, is subject to the test requirements of KDB 648474 D03 v01r04. 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 wrist bands. 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. 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 Software and Firmware 2.6 The test was conducted with firmware version 15R328 installed on the EUT. 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 Bluetooth LE Automation, Version 3.0. 2.7 EMI Suppression Device(s)/Modifications No EMI suppression device(s) were added and/or no modifications were made during testing.

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 7.10. 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. A raised turntable is used for radiated measurement. It is a continuously rotatable, remote-controlled, metallic turntable and 2 meters (6.56 ft.) in diameter. The turn table is flush with the raised floor of the chamber in order to maintain its function as a ground plane. 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).

Conducted Spurious Emissions 7.6 15.247(d) Test Overview and Limit For the following out of band conducted spurious emissions plots, the EUT was set to transmit at maximum power with the largest packet size available. The worst case spurious emissions were found in this configuration. The limit for out-of-band spurious emissions at the band edge is 20dB below the fundamental emission level, as determined from the in-band power measurement of the DTS channel performed in a 100kHz bandwidth per the procedure in Section 11.1 of KDB 558074 D01 v04. Test Procedure Used KDB 558074 D01 v04 Section 11.3 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 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 7-6.

Test Notes 1. RBW was set to 1MHz rather than 100kHz in order to increase the measurement speed. 2. The display line shown in the following plots denotes the limit at 20dB below the fundamental emission level measured in a 100kHz bandwidth. However, since the traces in the following plots are measured with a 1MHz RBW, the display line may not necessarily appear to be 20dB below the level of the fundamental in a 1MHz bandwidth. 3. For plots showing conducted spurious emissions near the limit, the frequencies were investigated with a reduced RBW to ensure that no emissions were present. FCC ID: BCG-A1891 Test Report S/N:

Test Notes 1. The optional test procedures for antenna port conducted measurements of unwanted emissions per the guidance of KDB 558074 D01 v04 were not used to evaluate this device for compliance to radiated limits. All radiated spurious emissions levels were measured in a radiated test setup. 2. All emissions lying in restricted bands specified in 15.205 are below the limit shown in Table 7-8. 3. The antenna is manipulated through typical positions, polarity and length during the tests. The EUT is manipulated through three orthogonal planes. 4. This unit was tested with its standard battery. 5. The spectrum is measured from 9kHz to the 10th harmonic of the fundamental frequency of the transmitter using CISPR quasi peak detector below 1GHz. Above 1 GHz, average and peak measurements were taken using linearly polarized horn antennas. The worst-case emissions are reported however emissions whose levels were not within 20dB of the respective limits were not reported. 6. Average measurements were recorded using a VBW of 3kHz, per Section 12.2.5.3 of KDB 558074 D01 v04, since 1/T is equal to just under 3kHz. This method was used because the EUT could not be configured to operate with a duty cycle > 98%. Both average and peak measurements were made using a peak detector 7. Emissions below 18GHz were measured at a 3 meter test distance while emissions above 18GHz were measured at a 1 meter test distance with the application of a distance correction factor. 8. No significant radiated band edge emissions were found in the 2310 2390MHz restricted band. 9. The "-" shown in the following RSE tables are used to denote a noise floor measurement. Sample Calculations Determining Spurious Emissions Levels o Field Strength Level [dBV/m] = Analyzer Level [dBm] + 107 + AFCL [dB/m]
o AFCL [dB/m] = Antenna Factor [dB/m] + Cable Loss [dB]
o Margin [dB] = Field Strength Level [dBV/m] Limit [dBV/m]
Radiated Band Edge Measurement Offset o The amplitude offset shown in the radiated restricted band edge plots in Section 7.8 was calculated using the formula:
Offset (dB) = (Antenna Factor + Cable Loss + Attenuator) Preamplifier Gain FCC ID: BCG-A1891 Test Report S/N:

V 6.6 06/06/2017 Test Notes 1. All emissions lying in restricted bands specified in 15.205 are below the limit shown in Table 7-12. 2. The broadband receive antenna is manipulated through vertical and horizontal polarizations during the tests. The EUT is manipulated through three orthogonal planes. 3. This unit was tested with its standard battery. 4. The spectrum is investigated using a peak detector and final measurements are recorded using CISPR quasi peak detector. The worst-case emissions are reported however emissions whose levels were not within 20dB of the respective limits were not reported. 5. Emissions were measured at a 3 meter test distance. 6. Emissions are investigated while operating on the center channel of the mode, band, and modulation that produced the worst case results during the transmitter spurious emissions testing. 7. No spurious emissions were detected within 20dB of the limit below 30MHz. 8. The results recorded using the broadband antenna is known to correlate with the results obtained by using a tuned dipole with an acceptable degree of accuracy. The VSWR for the measurement antenna was found to be less than 2:1. 9. The wide spectrum spurious emissions plots shown on the following pages are used only for the purpose of emission identification. There were no emissions detected in the 30MHz 1GHz frequency range, as shown in the subsequent plots. 10. The unit was tested with all possible mode and power schemes and only the highest emission is reported. FCC ID: BCG-A1891 Test Report S/N:
