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. 7.6.1.2 Measurement Results Performed by: Ryan McGann Figure 7.6.1.2-1: RF Conducted Emissions – LCH Figure 7.6.1.2-2: RF Conducted Emissions – MCH Figure 7.6.1.2-3: RF Conducted Emissions – HCH Report No: AT72127781-2P1 TÜV SÜD America, Inc.

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. 7.6.2.2 Measurement Results Performed by: Wayne Orwig Table 7.6.2.2-1: 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 2708.4 51.51 42.72 H -3.90 47.61 38.82 74.0 54.0 26.4 15.2 2708.4 52.06 43.88 V -3.90 48.16 39.98 74.0 54.0 25.8 14.0 Mid Channel 2744.4 53.01 46.71 H -3.80 49.21 42.91 74.0 54.0 24.8 11.1 2744.4 52.48 45.43 V -3.80 48.68 41.63 74.0 54.0 25.3 12.4 High Channel 2780.4 55.08 47.73 H -3.70 51.38 44.03 74.0 54.0 22.6 10.0 2780.4 53.37 47.40 V -3.70 49.67 43.70 74.0 54.0 24.3 10.3 7.6.2.3 Sample Calculation: RC = RU + CFT Where: CFT = Total Correction Factor (AF+CA+AG)-DC (Average Measurements Only) RU = Uncorrected Reading RC = Corrected Level AF = Antenna Factor CA = Cable Attenuation AG = Amplifier Gain DC = Duty Cycle Correction Factor Example Calculation: Peak Corrected Level: 51.51 - 3.90 = 47.61dBuV/m Margin: 74dBuV/m – 47.61dBuV/m = 26.4dB Example Calculation: Average Corrected Level: 42.72 - 3.90 - 0 = 38.82dBuV Margin: 54dBuV – 38.82dBuV = 15.2dB Report No: AT72127781-2P1 TÜV SÜD America, Inc.
