Standard Test Conditions Engineering Practices Except as noted herein, the following conditions and procedures were observed during the testing: In accordance with ANSI C63.10-2013 and unless otherwise indicated in the specific measurement results, the ambient temperature of the actual EUT was maintained within the range of 10° to 40°C (50° to 104°F) unless the particular equipment requirements specified testing over a different temperature range. Also, unless otherwise indicated, the humidity levels were in the range of 10% to 90% relative humidity. Measurement results, unless otherwise noted, are worst-case measurements. Environmental Conditions Temperature Humidity Pressure (ºC) (%) (mbar) 23.4 – 24.5 32.1 – 35.8 966 - 968 EUT Description Model: A03070/A03071 Description: Short Range Transceiver Firmware: N/A Software: N/A Serial Number: N/A Additional Information: The system consists of a base unit intended to be operated by the end user and a roaming device which is intended to be moving at various locations near the base unit. These devices are described as Base Unit (A03070) and Roaming Device (A03071). The devices utilize Zigbee, ANT, and BLE protocols for communication. The ANT and BLE emissions are identical so only one emission is included within the report. The Base Unit incorporates a MIMO configuration for the Zigbee communication.

Conducted RF Measurements (15.209) Engineer: Alex Macon Test Date: 9/18/17 Test Procedure Antenna-port conducted measurements were performed as an alternative to radiated measurements for demonstrating compliance in the restricted frequency bands for 15.209. The following offsets were added to the measurements: The maximum transmit antenna gain (in dBi) to the measured output power level to determine the EIRP level A maximum ground reflection factor to the EIRP level, 6 dB for frequencies ≤ 30 MHz, 4.7 dB for frequencies between 30 MHz and 1000 MHz, inclusive and 0 dB for frequencies > 1000MHz. The following equations were used to determine the field strength from the conducted values. E[dBμV/m] = EIRP[dBm] - 20 log(d[meters]) + 104.77, where E = field strength and d = 3m E[dBμV/m] = EIRP[dBm] + 95.2, for d = 3 meters. The Spectrum Analyzer was set to the following: The Spectrum Analyzer was set to the following for emissions > 1000MHz: a. RBW = 1 MHz b. VBW ≥ 3 MHz c. Detector = Peak. d. Sweep time = auto e. Trace mode = max hold 1. Note: For emissions where the peak exceeded that of the average 15.209 emission limit the following was performed. f. RBW = 1 MHz g. VBW ≤ RBW/100 (i.e., 10 kHz) but not less than 10 Hz For emissions below 1000MHz the Spectrum Analyzer settings were as follows: a. RBW = 100 kHz b. VBW ≥ 300 kHz c. Detector = Peak d. Sweep time = auto e. Trace mode = max hold The EUT was connected to a spectrum analyzer to verify that the EUT met the requirements for spurious emissions. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. The frequency range from 30 MHz to the 10th harmonic of the fundamental transmitter was investigated. Only noise floor was observed past 18GHz Test Setup 10dB Spectrum EUT attenuator Analyzer See Annex A1 and A2 for test data p1780018_FCC_Part 15.247_Rev 2.0 Page 10 of 18

Radiated Spurious Emissions Engineer: Alex Macon Test Date: 8/30/17 Test Procedure Radiated Spurious Emissions: 30 – 1000 MHz The EUT was setup in a semi-anechoic test chamber set 3m from the receiving antenna. The output of the transmitter was connected to a non-radiating balance load. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Emissions. The EUT was tested by rotating it 360 with the antennas in both the vertical and horizontal orientation and was raised from 1 to 4 meters to ensure the TX signal levels were maximized. All emissions from 30 MHz to 1 GHz were examined. Measured Level includes antenna and receiver cable correction factors. Correction factors were input into the spectrum analyzer before recording “Measured Level”. RBW = 100 KHz VBW = 300 KHz Detector – Quasi Peak Test Setup EUT Antenna Spectrum Analyzer Test Procedure for Radiated Spurious Emissions above 1 GHz The EUT was setup in a semi-anechoic test chamber set 3m from the receiving antenna. The output of the transmitter was connected to a non-radiating balance load. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Emissions. The EUT was tested by rotating it 360 with the antennas in both the vertical and horizontal orientation and was raised from 1 to 4 meters to ensure the TX signal levels were maximized.

15.247 Spurious Emissions Engineer: Alex Macon Test Date: 8/28/17 Test Procedure For the Base Unit, The EUT was connected directly to a spectrum analyzer. The Spectrum Analyzer was set to the following: RBW = 100 kHz VBW ≥ 3 x RBW Peak Detector Trace mode = max hold Sweep = auto couple Frequency Range = 30MHz – 10th Harmonic of the fundamental The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. The trace was allowed to stabilize. All emissions were investigated to insure they were attenuated from the peak fundamental by at least 20dB. If the average power levels were measured then the out-of-band emissions needed to be attenuated by 30dB. In addition emissions were investigated at the band edges to insure all out-of-band emissions were attenuated 20 or 30dB as necessary. Test Setup 10dB Spectrum EUT attenuator Analyzer Test Procedure for the Roaming Device The EUT was setup in a semi-anechoic test chamber set 3m from the receiving antenna. The output of the transmitter was connected to a non-radiating balance load. The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Emissions.

DTS Bandwidth Engineer: Alex Macon Test Date: 9/11/17 Test Procedure The EUT was connected directly to a spectrum analyzer. The Spectrum Analyzer was set to the following: RBW = 100 kHz VBW ≥ 3 x RBW Peak Detector Trace mode = max hold Sweep = auto couple Span = 1.5 x EBW The EUT was set to transmit at the lowest, middle and highest channels of the band at the maximum power levels. The maximum width of the emission that was determined by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that were attenuated by 6db and this value was used to determine the width of the carrier. Alternatively the spectrum analyzer’s automatic bandwidth capability was used.
