The chamber is lined with Toyo Ferrite Grid Absorber, model number FFG-1000. The ferrite tile grid is 101 x 101 x 19mm thick and weighs approximately 550 grams. These tiles are mounted on steel panels and installed directly on the inner walls of the chamber. The turntable is 5’ in diameter and 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 ground plane using 3/4" stainless steel braided cable. The turntable is all steel, flush mounted EMCO Model 1060 installed in an all steel frame. The table is remotely operated from inside the control room located 25’ from the range. The turntable is electrically bonded to the surrounding ground plane via steel fingers installed on the edge of the turn table. The steel fingers make constant contact with the ground plane during operation. Behind the turntable is a 3’ x 6’ x 4’ deep shielded pit used for support equipment if necessary. The pit is equipped with 1 - 4” PVC chase from the turntable to the pit that allows for cabling to the EUT if necessary. The underside of the turntable can be accessed from the pit so cables can be supplied to the EUT from the pit. The chamber rear wall is covered with a mixture of Siepel pyramidal absorber. The side walls of the chamber are partially covered with Siepel pyramidal absorber. 30’ Dimensions Not to Scale 5’6” 20’ 9’8” 3 Meters 4’3” Figure 2.3.1-1: Semi-Anechoic Chamber Test Site – Chamber A Report: AT72150545-1C0 Page 5

Model(s): SC4240E-235470-BB FCC ID: N2S-SC42E-235470 7 SUMMARY OF TESTS Along with the tabular data shown below, plots were taken of all signals deemed important enough to document. 7.1 26dB Bandwidth and Emission Mask – §2.1049 / §90.210(m) 7.1.1 Measurement Procedure The 26dB bandwidth was measured in accordance with Subclause 5.4.3 of ANSI C63.26. 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. The trace was set to max hold with a peak detector active. The ndB down function of the spectrum analyzer was utilized to determine the 26 dB bandwidth of the emission. To show compliance with the emission mask requirements defined in Section 90.210(m), the measurement guidance in KDB 971168 D01 Power Meas License Digital Systems v03r01, Section 6.1. The spectrum analyzer span was set to 150% of the signal bandwidth and the resolution bandwidth was set to a minimum of 1% of the occupied bandwidth. An average detector was applied using a single sweep with the sweep time set to 1ms per sweep point. The resulting trace was compared to the Mask M requirements. 7.1.2 Measurement Results Performed by: Jeremy Pickens Table 7.1.2-1: 26dB Bandwidth Frequency 26dB Bandwidth Modulation (MHz) (MHz) 4945 9.839 OFDM 4965 9.857 4985 9.980 Report: AT72150545-1C0 Page 9

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, RMS measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000 MHz, RMS measurements were made with RBW and VBW of 1 MHz and 3 MHz respectively. Cabinet radiation measurements were recorded with the antenna ports terminated into 50-Ohms through attenuators. Limit from §90.210(m): On any frequency removed from the assigned frequency between above 150% of the authorized bandwidth: 50 dB or 55 + 10 log (P) dB, whichever is the lesser attenuation. The device was configured for 27dBm output power per port, so the applied limit was -23dBm or 72.2dBµV/m at 3 meters. 7.7.2 Measurement Results Performed by: Jeremy Pickens Table 7.7.2-1: Radiated Spurious Emissions Tabulated Data Level Antenna Correction Corrected Level Limit Margin Frequency (dBuV) Polarity Factors (dBµV/m) (dBµV/m) (dB) (MHz) pk RMS (H/V) (dB) pk RMS pk RMS pk RMS Low Channel - 4945MHz 9890 45.70 33.20 H 15.61 -- 48.81 -- 72.2 -- 23.4 9890 46.2 33.1 V 15.61 -- 48.71 -- 72.2 -- 23.5 Mid Channel - 4965MHz 9930 45.9 33.2 H 15.65 -- 48.85 -- 72.2 -- 23.3 9930 46 33.1 V 15.65 -- 48.75 -- 72.2 -- 23.4 High Channel - 4985MHz 9970 46.3 33 H 15.69 -- 48.69 -- 72.2 -- 23.5 9970 46 33.1 V 15.69 -- 48.79 -- 72.2 -- 23.4 Report: AT72150545-1C0 Page 18
