Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix A A. RADIATED RF SPURIOUS EMISSIONS – 30 MHZ TO 10 GHZ Purpose: This test performed to determine if the EUT meets the radiated RF emission requirements of the FCC Part 74 Subpart H over the frequency range from 30MHz to 10GHz. An Average detector was used for the measurements. Requirements: As stated in FCC Part 74, Subpart H, 74.861, radiated spurious emissions 74.861 subsection 6 iii, spurious emissions must meet the limits specified in section 8.4 of ETSI EN 300 422-1 V1.4.2 (2011-08) Measurement Uncertainty: All measurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement system. Values of Expanded Measurement Uncertainty (95% Confidence) Measurement Type Ulab UETSI Radiated disturbance (electric field strength on an open area test 4.12 dB 6.00 dB site or alternative test site) (30 MHz – 1000 MHz) Radiated disturbance (electric field strength on an open area test 4.56 dB 6.00 dB site or alternative test site) (1 GHz – 13 GHz) Ulab = Determined for Shure EMC Laboratory UETSI = From ETSI EN 300 422-1 Table 6 Since Ulab is less than or equal to UETSI: - Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit; Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance limit. Test Setup and Instrumentation: A Shure model WL93 was plugged into the EUT microphone socket. Photographs of the test setup are shown in Figure 1 and Figure 2. The test instrumentation can be determined from Table 10-1. EUT Operation: The EUT was powered up and the frequency of the transmitter was selected using the front panel controls. The EUT was checked for proper operation after it was setup on the table. For radiated spurious emission and necessary bandwidth testing, the testing was conducted with the EUT set to the middle frequency within the operating frequency range, and at 10mW RF output.

Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix A Specific Test Procedures: All tests were performed in a 28ft. x 20ft. x 18.5ft. 3m semi-anechoic test chamber. The walls and ceiling of the shielded chamber are lined with ferrite tiles. Anechoic absorber material is installed over the ferrite tile. The floor of the chamber is used as the ground plane. The chamber complies with ANSI C63.4-2003 for site attenuation. The shielded enclosure prevents emissions from other sources, such as radio and TV stations from interfering with the measurements. All power lines and signal lines entering the enclosure pass through filters on the enclosure wall. The power line filters prevent extraneous signals from entering the enclosure on these leads. BLOCK DIAGRAM OF SHIELDED ENCLOSURE Preliminary radiated measurements were performed to determine the frequencies where the significant emissions might be found. With the EUT at one set position and the measurement antenna at a set height (i.e. without maximizing), the radiated emissions were measured using a peak detector and automatically plotted. The BiConiLog measuring antenna was positioned at a 3 meter distance from the EUT. Page 10 of 26

Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix A All significant broadband and narrowband signals found in the preliminary sweeps were then measured using a peak detector at a test distance of 3 meters. The measurements were made with a BiConiLog antenna over the frequency range of 30 MHz to 1 GHz, and a double ridged waveguide antenna over the frequency range of 1 GHz to 10 GHz. To ensure that maximum emission levels were measured, the following steps were taken: i. The EUT was rotated so that all of its sides were exposed to the receiving antenna. ii. Since the measuring antennas are linearly polarized, both horizontal and vertical field components were measured. iii. The measuring antenna was raised and lowered from 1 to 4 meters for each antenna polarization to maximize the readings. The equivalent power was determined from the field intensity levels measured at 3 meters using the substitution method. To determine the emission power, another antenna was set in place of the EUT and connected to a calibrated signal generator. (A tuned dipole was used for all measurements below 1GHz and a double ridged waveguide antenna was used for all measurements above 1GHz.) The output of the signal generator was adjusted to match the received level at the EMI receiver. The signal level was recorded. The reading was corrected to compensate for cable loss and antenna gain. Results: The plots of the peak preliminary radiated voltage levels and maximized peak radiated voltage levels results are presented on page 12 thru page 17. The ERP measurements are shown on page 18. All emissions measured from the EUT were within the ETSI EN 300 422-1 specification limits. Figure 1: QLXD1 Transmitter Test Setup Figure 2: QLXD1 Transmitter Test Setup Page 11 of 26

Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix B B. Power Output Purpose: This test performed to determine if the EUT meets the Power Output requirements of the FCC Part74H, Section 74.861. Requirements: As stated in FCC 74H Section 74.861, the maximum radiated power in the 600MHz guard band and the 600MHz duplex gap: 20mW EIRP. Measurement Uncertainty: All measurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement system. Values of Expanded Measurement Uncertainty (95% Confidence) Measurement Type Ulab Conducted measurements (30 MHz – 1000 MHz) 1.24 dB Ulab = Determined for Shure EMC Laboratory Since Ulab is less than or equal to UETSI: - Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit; Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance limit. Test Setup and Instrumentation: Photographs of the test setup are shown in Figure 1. The test instrumentation can be determined from Table 10-1. EUT Operation: The EUT was powered up and the frequency of the transmitter was selected using the front panel controls. For rated output power, the testing was conducted with the EUT set to the middle frequency within the operating frequency range, and at 10mW RF output. Page 19 of 26

Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix B Specific Test Procedures: The output of the EUT was connected to a spectrum analyzer through 20dB of attenuation. The EUT was set to transmit on the middle frequency. The channel power was measured. The spectrum analyzer was set to: RBW 10kHz VBW 100kHz Channel BW 200kHz Span 1MHz Detector Average State Average Results: The EIRP for the middle frequency meets the FCC74H 74.861 requirements.

Engineering Test Report No. SEL-030/QLXD1 J50A Part74H Appendix C NECESSARY BANDWIDTH MEASUREMENTS B.1 PURPOSE This test was performed to determine if the EUT meets the occupied bandwidth requirements of EN 300 422-1, section 8.3.3., with the EUT operating at 589.500MHz and at 10mW RF Output. B.2 REQUIREMENTS As stated in EN 300 422-1, section 8.3.3, the emission mask given in section 8.3.3.2 shall not be exceeded. B.3 TEST SETUP AND INSTRUMENTATION A photograph of the test setup is shown in Figure B-1. The test instrumentation can be determined from Table 10-1. B.4 MEASUREMENT UNCERTAINTY All measurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement system. Values of Expanded Measurement Uncertainty (95% Confidence): Measurement Type ULAB Necessary Bandwidth ±0.130 % Ulab = Determined for Shure EMC Laboratory Since ULAB is less than or equal to UETSI: - Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit; - Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance limit. B.5 EUT OPERATION The EUT was powered up and the transmit frequency and power output of the EUT were selected. The EUT was checked for proper operation after it was setup for the test. Testing was conducted with the EUT set to transmit at 589.500MHz, at an output power level of 10mW. The transmitter was modulated per EN300422-1 V1.4.2 (2011-08), clause 7.1.2. B.6 TEST PROCEDURE The test procedure followed is shown in EN300422-1 V1.4.2 (2011-08), section 8.3.3.1. Page 22 of 26
