Model(s): ACT2 FCC ID: SK9ACT2 IC: 864G-ACT2 2.3 Radiated Emissions Test Site Description 2.3.1 Semi-Anechoic Chamber Test Site The Semi-Anechoic Chamber Test Site consists of a 20’W x 30’L x 20’H shielded enclosure. The chamber is lined with ETS-Lindgren Ferrite Absorber, model number FT-1500. The ferrite tile 600 mm x 600 mm (2.62 in x 23.62 in) panels and are mounted directly on the inner walls of the chamber shield. The specular regions of the chamber are lined with additional ETS-Lindgren PS-600 hybrid absorber to extend its frequency range up to 18GHz and beyond. The turntable is a 2m ETS-Lindgren Model 2170, and installed off the center axis is located 5’6” from the back wall of the chamber. The chamber is grounded via 1 - 8’ copper ground rod, installed at the center of the back wall, it is bound to the shield using #8 solid copper wire. The antenna mast is an EMCO 1060 and is remotely controlled from the control room for both antenna height and polarization.

The measurement probe was located 20 centimeters away from the EUT on an adjustable antenna mast. The EUT was rotated through 360 degrees so that the maximum radiated emissions level would be detected. The mast was adjusted until the evaluated results are less than 10% of the applicable limit. Once a stable reading was obtained, the maximum was recorded. The azimuth and elevation leading to the direction of maximum exposure was identified. The evaluation points in the horizontal plane were along radials extending from the antenna axis 45 degrees apart starting from the direction of maximum exposure. 7.1.2 Measurement Results Performed by: Ryan McGann Table 7.1.2-1: Maximum Permissible Exposure – 900MHz Radio – X-orientation ISED Probe Field Power Frequency Distance Azimuth Elevation Probe FCC Limit Canada Display Strength Density Result Factor Limit (MHz) cm degrees cm V/m V/m mW/cm2 mW/cm2 mW/cm2 927.6 20 315 159 8.234 1.26 10.3748 0.028551 0.6184 0.27927356 PASS 927.6 20 270 147 8.134 1.26 10.2488 0.027862 0.6184 0.27927356 PASS 927.6 20 225 165 6.88 1.26 8.6688 0.019933 0.6184 0.27927356 PASS 927.6 20 180 152 8.256 1.26 10.4026 0.028704 0.6184 0.27927356 PASS 927.6 20 135 153 6.244 1.26 7.86744 0.016418 0.6184 0.27927356 PASS 927.6 20 90 175 6.296 1.26 7.93296 0.016693 0.6184 0.27927356 PASS 927.6 20 45 151 6.567 1.26 8.27442 0.018161 0.6184 0.27927356 PASS 927.6 20 0 149 8.35 1.26 10.521 0.029361 0.6184 0.27927356 PASS 927.6 20 315 157 8.236 1.26 10.3774 0.028565 0.6184 0.27927356 PASS Table 7.1.2-2: Maximum Permissible Exposure – 900MHz Radio – Y-orientation ISED Probe Field Power Frequency Distance Azimuth Elevation Probe FCC Limit Canada Display Strength Density Result Factor Limit (MHz) cm degrees cm V/m V/m mW/cm2 mW/cm2 mW/cm2 927.6 20 330 156 9.952 1.26 12.5395 0.041708 0.6184 0.27927356 PASS 927.6 20 15 157 8.654 1.26 10.904 0.031538 0.6184 0.27927356 PASS 927.6 20 60 150 5.577 1.26 7.02702 0.013098 0.6184 0.27927356 PASS 927.6 20 105 161 5.299 1.26 6.67674 0.011825 0.6184 0.27927356 PASS 927.6 20 150 158 6.415 1.26 8.0829 0.01733 0.6184 0.27927356 PASS 927.6 20 195 160 6.93 1.26 8.7318 0.020224 0.6184 0.27927356 PASS 927.6 20 240 161 8.031 1.26 10.1191 0.027161 0.6184 0.27927356 PASS 927.6 20 285 162 9.285 1.26 11.6991 0.036305 0.6184 0.27927356 PASS 927.6 20 330 157 9.981 1.26 12.5761 0.041952 0.6184 0.27927356 PASS Report: AT72139651-4C0 Page 9
