Report Number: F690501/RF-RTL013933 Page: 11 of 34 2.3. Test Procedures Radiated emissions from the EUT were measured according to the dictates in section 11.11 & 11.12 of ANSI C63.10-2013. 2.3.1. Test Procedures for emission below 30 ㎒ 1. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter anechoic chamber test site. The table was rotated 360 degrees to determine the position of the highest radiation. 2. Then antenna is a loop antenna is fixed at one meter above the ground to determine the maximum value of the field strength. Both parallel and perpendicular of the antenna are set to make the measurement. 3. For each suspected emission, the EUT was arranged to its worst case and then the table was turned from 0 degrees to 360 degrees to find the maximum reading. 4. The test-receiver system was set to average or quasi peak detect function and Specified Bandwidth with Maximum Hold Mode. 2.3.2. Test Procedures for emission from above 30 ㎒ 1. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter anechoic chamber test site below 1 ㎓ and 1.5 meters above the ground at a 3 meter anechoic chamber test site above 1 ㎓. The table was rotated 360 degrees to determine the position of the highest radiation. 2. During performing radiated emission below 1 ㎓, the EUT was set 3 meters away from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. During performing radiated emission above 1 ㎓, the EUT was set 3 meter away from the interference receiving antenna. 3. The antenna is a bi-log antenna, a horn antenna and its height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. 4. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the table was turned from 0 degrees to 360 degrees to find the maximum reading. 5. The test receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. 6. If the emission level of the EUT in peak mode was 10 ㏈ lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10 ㏈ margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet.

Report Number: F690501/RF-RTL013933 Page: 12 of 34 Note; All channels were investigated for radiated spurious emissions. Only the radiated emissions of the configuration that produced the worst case emissions are reported in this section. 1. Unwanted Emissions into Non-Restricted Frequency Bands - The Reference Level Measurement refer to section 11.11.2 Set analyzer center frequency to DTS channel center frequency, SPAN ≥ 1.5 times the DTS bandwidth, the RBW = 100 ㎑ and VBW ≥ 3ⅹRBW, Detector = Peak, Sweep time = Auto couple, Trace = Max hold. - Unwanted Emissions Level Measurement refer to section 11.11.3 Set the center frequency and span to encompass frequency range to be measured, the RBW = 100 ㎑ and VBW ≥ 3ⅹRBW, Detector = Peak, Sweep time = Auto couple, Trace = Max hold. 2. Unwanted Emissions into Restricted Frequency Bands - Peak Power measurement procedure refer to section 11.12.2.4 Set RBW = as specified in Table 9, VBW ≥ 3 x RBW, Detector = Peak, Sweep time = auto, Trace = Max hold. Table 9– RBW as a function of frequency Frequency RBW 9 ㎑ to 150 ㎑ 200 ㎐ to 300 ㎐ 0.15 ㎒ to 30 ㎒ 9 ㎑ to 10 ㎑ 30 ㎒ to 1 000 ㎒ 100 ㎑ to 120 ㎑ > 1 000 ㎒ 1 ㎒ If the peak – detected amplitude can be shown to comply with the average limit, then it is not necessary to perform a separate average measurement. -Average Power measurements procedure refer to section 11.12.2.5.2 The EUT shall be configured to operate at the maximum achievable duty cycle. Measure the duty cycle D of the transmitter output signal as described in section 11.6. Set RBW = 1 ㎒, VBW ≥ 3 x RBW, Detector = RMS, if span / (# of points in sweep) ≤ (RBW/2). Satisfying this condition may require increasing the number of points in the sweep or reducing the span. If this condition cannot be satisfied then the detector mode shall be set to peak. Averaging type = power (i.e., RMS). As an alternative the detector and averaging type may be set for linear voltage averaging. Some instruments require linear display mode in order to use linear voltage averaging. Log or ㏈ averaging shall not be used. Sweep time = auto, Perform a trace average of at least 100 traces. A correction factor shall be added to the measurement results prior to comparing to the emission limit in order to compute the emission level that would have been measured had the test been performed at 100 percent duty cycle. The correction factor is computed as follows: 1) If power averaging (rms) mode was used in step f), then the applicable correction factor is [10 log(1 / D)], where D is the duty cycle. 3. Definition of DUT Axis. Definition of the test orthogonal plan for EUT was described in the test setup photo. The test orthogonal plan of EUT is Z – axis during radiation test.

Only the radiated emissions of the configuration that produced the worst case emissions are reported in this section. Per the guidance of ANSI C63.10-2013, section 11.11.1 & 11.11.2 & 11.11.3, the reference level for out of band emissions is established from the plots of this section since the band edge emissions are measured with a RBW of 100 ㎑. This reference level is then used as the limit in subsequent plots for out of band spurious emissions shown in section 2.4.3. The limit for out of band spurious emission at the band edge is 20 ㏈ below the fundamental emission level measured in a 100 ㎑ bandwidth. 1. Conducted Emissions at Band Edge - The Measurement refer to section 11.11.2 Set the center frequency and span to encompass frequency range to be measured, the RBW = 100 ㎑ and VBW ≥ 3 x RBW, Detector = Peak, Sweep time = Auto couple, Trace mode = Max hold, The trace was allowed to stabilize. 2. Conducted Spurious Emissions - The Measurement refer to section 11.11.3 Start frequency was set to 9 ㎑ and stop frequency was set to 25 ㎓ (separated into two plots per channel), RBW = 1 ㎒, VBW ≥ 3 x RBW, Detector = Peak, Sweep time = Auto couple, Trace = Max hold, The trace was allowed to stabilize. 3. TDF function - For plots showing conducted spurious emissions from 9 ㎑ to 25 ㎓, all path loss of wide frequency range was investigated and compensated to spectrum analyzer as TDF function. So, the reading values shown in plots were final result. The results of this test report are effective only to the items tested.

Limit According to §15.247(b)(3), for systems using digital modulation in the 902-928 ㎒, 2 400-2 483.5 ㎒, and 5 725-5 850 ㎒ bands: 1 Watt. As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. According to §15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is based on the use of antenna with directional gains that do not exceed 6 ㏈i. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 ㏈i are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraph (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in ㏈ that the directional gain of the antenna exceeds 6 ㏈i.

Report Number: F690501/RF-RTL013933 Page: 29 of 34 4.3. Test Procedure The test follows section 11.9.1.3 of ANSI C63.10-2013. PKPM1 Peak-reading power meter method - The maximum peak conducted output power may be measured using a broadband peak RF power meter. The power meter shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. The test follows section 11.9.2.3.2 of ANSI C63.10-2013. Method AVGPM-G (Measurement using a gated RF average-reading power meter) - Alternatively, measurements may be performed using a wideband gated RF power meter provided that the gate parameters are adjusted such that the power is measured only when the EUT is transmitting at its maximum power control level. Since this measurement is made only during the ON time of the transmitter, no duty cycle correction is required. Test program: (S/W name: R&S Power Viewer, Version: 3.2.0) 1. Initially overall offset for attenuator and cable loss is measured per frequency. 2. Measured offset is inserted in test program in advance of measurement for output power. 3. Power for each frequency (channel) of device is investigated as final result. 4. Final result reported on this section from R&S power viewer program includes with several factors and test program shows only final result.
