Radiated emissions Frequency Uncertainty (Ulab) 30MHz ~ 200MHz (Horizontal) 4.59dB 30MHz ~ 200MHz (Vertical) 4.49dB 200MHz ~1000MHz (Horizontal) 4.94dB 200MHz ~1000MHz (Vertical) 4.97dB 1GHz ~6GHz 4.52dB 6GHz ~18GHz 4.58dB Line-conducted emissions Frequency Uncertainty (Ulab) 150kHz~30MHz 2.80dB Page 6 of 17 FCC ID: P5FSPC1107

TEST REPORT Report No. : AW0016632(7) Date : 03 Apr 2018 3 Description of the emission test 3.1 Test Procedure Radiated emissions measurements are investigated and taken pursuant to the procedures of ANSI C63.10 – 2013. The equipment under test (EUT) was placed on a non-conductive turntable with dimensions of 1.5m x 0.4m and 0.8m high above the ground for below 1GHz measurement and 1.5m high above the ground for above 1GHz measurement. 3m from the EUT, a broadband antenna mounting on the mast received the signal strength. The turntable was rotated to maximize the emission level. The antenna was then moving along the mast from 1m up to 4m until no more higher value was found. Both horizontal and vertical polarization of the antenna were placed and investigated. For 30MHz to 200MHz, biconical antenna with its vertical and horizontal plane is placed 3m from the EUT and rotated about its vertical and horizontal axis for maximum response at each azimuth about the EUT. And the reference point of antenna shall be 1 m above the ground. Same procedure for frequency 200MHz to 1000MHz but Log-periodic antenna is used for final measurements. For above 1GHz, horn antenna with its vertical and horizontal plane is placed 3m from the EUT and rotated about its vertical and horizontal axis for maximum response at each azimuth about the EUT. The device was rotated through three orthogonal axes to determine which attitude and configuration produce the highest emission during measurement. The Frequencies from fundamental up to the tenth harmonics were investigated, and emissions more 20dB below limit were not reported. Peak Detector data was measured unless otherwise stated. An engineer sample with continuous transmission was used for measurements. Test Result: It was found that the EUT meet the FCC requirement. Page 7 of 17 FCC ID: P5FSPC1107

TEST REPORT Report No. : AW0016632(7) Date : 03 Apr 2018 3.3 Average Factor The average factor is simply the on-time divided by the period: Each pulse width = 0.5ms Number of pulse for worst case duty cycle = 36 pulses Note: Where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute voltage during a 0.1 second interval. Duty Cycle = (0.5 x 36 / 100) = 0.18 Therefore, the average factor is found by 20 log10 0.18 = -14.8 dB The Appendix A5 shows the plot of duty cycle. 3.4 Transmission time Transmission time = 900ms Requirement: below 1000ms Silent time = 49.6s Requirement: longer than 10s and 27s (0.9s x 30) The transmission time was complied with 15.231(e) requirements.
