The span of the spectrum analyzer display was set between two times and five times the occupied bandwidth (OBW) of the emission. The RBW of the spectrum analyzer was set to 100kHz. The trace was set to max hold with a peak detector active. The ndB down measurement functions of the analyzer were utilized to determine the 6 dB DTS bandwidth of the emission. The occupied bandwidth measurement function of the spectrum analyzer was used to measure the 99% bandwidth. The span of the analyzer was set to capture all products of the modulation process, including the emission sidebands. The resolution bandwidth was set from 1% to 5% of the occupied bandwidth and the video bandwidth set to at least 3 times the resolution bandwidth. A peak detector was used. 7.3.2 Measurement Results Performed by: Jeremy Pickens Table 7.3.2-1: 6dB / 99% Bandwidth Frequency 6dB Bandwidth 99% Bandwidth [MHz] [kHz] [kHz] 905 511.9 587.55 915 512.3 587.55 924 510.7 581.77 Figure 7.3.2-1: 6dB Bandwidth – LCH Figure 7.3.2-2: 6dB Bandwidth – MCH Report: AT72143104-1C1 Page 12

The RF output of the equipment under test was directly connected to the input of the power meter applying suitable attenuation. 7.4.2 Measurement Results Performed by: Jeremy Pickens Table 7.4.2-1: Maximum Conducted Output Power (Peak) Frequency Level [MHz] [dBm] 905 18.21 915 17.96 924 17.86 Report: AT72143104-1C1 Page 14

Model(s): WMS-0001 FCC ID: MTFWMS-0001 IC: 2175D-WMS0001 7.5 Emission Levels 7.5.1 Emissions into Non-Restricted Frequency Bands – FCC: Section 15.247(d); ISED Canada: RSS-247 5.5 7.5.1.1 Measurement Procedure The unwanted emissions into non-restricted bands were measured conducted in accordance with ANSI C63.10, Clause 11.11.13. The RF output of the equipment under test was directly connected to the input of the spectrum analyzer applying suitable attenuation. The Resolution Bandwidth (RBW) of the spectrum analyzer was set to 100 kHz. The Video Bandwidth (VBW) was set to ≥ 300 kHz. Span was set to 1.5 times the DTS bandwidth centered on each channel evaluated. The trace was set to max hold with a peak detector active. The resulting spectrum analyzer peak level was used to determine the reference level with respect to the 20 dBc limit. The spectrum span was then adjusted for the measurement of spurious emissions from 30 MHz to 10 GHz, 10 times the highest fundamental frequency. Band-edge compliance was determined using the conducted marker-delta method in which the radio frequency power that is produced by the EUT is at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of desired power. 7.5.1.2 Measurement Results Performed by: Jeremy Pickens Figure 7.5.1.2-1: 30 MHz – 10 GHz – Low Channel Figure 7.5.1.2-2: 30 MHz – 10 GHz – Middle Channel Report: AT72143104-1C1 Page 15

Model(s): WMS-0001 FCC ID: MTFWMS-0001 IC: 2175D-WMS0001 7.5.2 Emissions into Restricted Frequency Bands – FCC: Sections 15.205, 15.209; ISED Canada: RSS-Gen 8.9 / 8.10 7.5.2.1 Measurement Procedure The unwanted emissions into restricted bands were measured radiated over the frequency range of 30 MHz to 10 GHz, 10 times the highest fundamental frequency. The EUT was rotated through 360° and the receive antenna height was varied from 1 meter to 4 meters so that the maximum radiated emissions level would be detected. For frequencies below 1000 MHz, quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000 MHz, peak and average measurements were made with RBW and VBW of 1 MHz and 3 MHz respectively. Each emission found to be in a restricted band as defined by section 15.205, including any emission at the operational band-edge, was compared to the radiated emission limits as defined in section 15.209. 7.5.2.2 Measurement Results Performed by: Tyler Leeson Table 7.5.2.2-1: Radiated Spurious Emissions Tabulated Data Level Antenna Correction Corrected Level Limit Margin Frequency (dBuV) Polarity Factors (dBuV/m) (dBuV/m) (dB) (MHz) pk Qpk/Avg (H/V) (dB) pk Qpk/Avg pk Qpk/Avg pk Qpk/Avg Low Channel 2715 50.10 38.80 H 0.41 50.51 39.21 74.0 54.0 23.5 14.8 2715 50.50 38.40 V -3.06 47.44 35.34 74.0 54.0 26.6 18.7 3620 52.80 41.50 H 2.16 54.96 43.66 74.0 54.0 19.0 10.3 3620 49.90 37.30 V 0.12 50.02 37.42 74.0 54.0 24.0 16.6 4525 51.20 39.90 H 5.21 56.41 45.11 74.0 54.0 17.6 8.9 4525 51.20 40.10 V 1.75 52.95 41.85 74.0 54.0 21.0 12.1 5430 51.90 40.50 H 7.60 59.50 48.10 74.0 54.0 14.5 5.9 5430 49.80 37.50 V 4.97 54.77 42.47 74.0 54.0 19.2 11.5 Middle Channel 2745 49.70 38.90 H 0.50 50.20 39.40 74.0 54.0 23.8 14.6 2745 50.20 39.10 V -2.95 47.25 36.15 74.0 54.0 26.8 17.9 3660 53.90 43.70 H 2.34 56.24 46.04 74.0 54.0 17.8 8.0 3660 51.60 39.90 V 0.24 51.84 40.14 74.0 54.0 22.2 13.9 4575 50.70 39.70 H 5.30 56.00 45.00 74.0 54.0 18.0 9.0 4575 51.80 40.90 V 1.97 53.77 42.87 74.0 54.0 20.2 11.1 High Channel 2772 49.60 37.10 H 0.58 50.18 37.68 74.0 54.0 23.8 16.3 2772 51.20 38.10 V -2.86 48.34 35.24 74.0 54.0 25.7 18.8 3696 54.40 44.20 H 2.50 56.90 46.70 74.0 54.0 17.1 7.3 3696 54.20 43.30 V 0.35 54.55 43.65 74.0 54.0 19.4 10.3 4620 49.20 37.90 H 5.38 54.58 43.28 74.0 54.0 19.4 10.7 4620 50.60 40.10 V 2.16 52.76 42.26 74.0 54.0 21.2 11.7 Report: AT72143104-1C1 Page 17
