Model: C1A3B FCC ID: SK9C1A-3B IC: 864G-C1A3B 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’ x 30’ x 18’ shielded enclosure. 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 150cm in diameter and is located 160cm 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 table 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 chases from the turntable to the pit that allow 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. A diagram of the Semi-Anechoic Chamber Test Site is shown in Figure 2.3-1 below: 3 Meters 5 Feet Diameter 20 Feet 30 Feet Figure 2.3-1: Semi-Anechoic Chamber Test Site ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 5

Model: C1A3B FCC ID: SK9C1A-3B IC: 864G-C1A3B 2.3.2 Open Area Tests Site (OATS) The open area test site consists of a 40’ x 66’ concrete pad covered with a perforated electro- plated galvanized sheet metal. The perforations in the sheet metal are 1/8” holes that are staggered every 3/16”. The individual sheets are placed to overlap each other by 1/4” and are riveted together to provide a continuous seam. Rivets are spaced every 3” in a 3 x 20 meter perimeter around the antenna mast and EUT area. Rivets in the remaining area are spaced as necessary to properly secure the ground plane and maintain the electrical continuity. The entire ground plane extends 12’ beyond the turntable edge and 16’ beyond the antenna mast when set to a 10 meter measurement distance. The ground plane is grounded via 4 – 8’ copper ground rods, each installed at a corner of the ground plane and bound to the ground plane using 3/4” stainless steel braided cable. The turntable is an all aluminum 10’ flush mounted table installed in an all aluminum frame. The table is remotely operated from inside the control room located 40’ 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. Adjacent to the turntable is a 7’ x 7’ square and 4’ deep concrete pit used for support equipment if necessary. The pit is equipped with 5 – 4” PVC chases from the pit to the control room that allow 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 pit is covered with 2 sheets of 1/4” diamond style re-enforced steel sheets. The sheets are painted to match the perforated steel ground plane; however the underside edges have been masked off to maintain the electrical continuity of the ground plane. All reflecting objects are located outside of the ellipse defined in ANSI C63.4. A diagram of the Open Area Test Site is shown in Figure 2.3-2 below: 10Meter 3 Meters 40Feet 7x7x4 Pit 66 Feet Figure 2.3-2: Open Area Test Site ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 6

As described in the theory of operation, the maximum channel transmitter dwell time is 45ms per channel hop with the minimum period of 30seconds between hops on the same channel. Therefore the maximum time of occupancy on any one channel within a 20s period is <400ms for all modes of operation. ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 15

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 approximately 1 % to 5 % of the OBW. The trace was set to max hold with a peak detector active. The Delta and ndB down functions of the analyzer were utilized to determine the 20 dB 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 to 1% to 5% of the occupied bandwidth. The video bandwidth was set to 3 times the resolution bandwidth. A peak detector was used. 7.4.4.2 Measurement Results Table 7.4.4.2-1: 20dB / 99% Bandwidth Frequency 20dB Bandwidth 99% Bandwidth [MHz] [kHz] [kHz] 909.6 101.8 137.0 916.2 119.1 150.4 921.8 149.0 162.5 Figure 7.4.4.2-1: 20dB BW Low Channel Figure 7.4.4.2-2: 20dB BW Low Channel ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 16

The EUT was investigated for conducted spurious emissions from 30MHz to 10GHz, 10 times the highest fundamental frequency. Measurements were made at the low, center and high channels of the EUT. For each measurement, the spectrum analyzer’s RBW was set to 100kHz. A peak detector function was used with the trace set to max hold. 7.5.2.2 Measurement Results Figure 7.5.2.2-1: 30 MHz – 10 GHz – Low Channel Figure 7.5.2.2-2: 30 MHz – 10 GHz – Mid Channel Figure 7.5.2.2-3: 30 MHz – 10 GHz –High Channel ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 19

The EUT was rotated through 360° and the receive antenna height was varied from 1m to 4m so that the maximum radiated emissions level would be detected. For frequencies below 1000MHz, quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000MHz, peak and average measurements were made with RBW and VBW of 1 MHz and 3MHz respectively. Each emission found to be in a restricted band was compared to the applicable radiated emission limits. 7.5.3.2 Duty Cycle Correction For average radiated measurements, using a 45% duty cycle, the measured level was reduced by a factor 6.94dB. The duty cycle correction factor is determined using the formula: 20log (45/100) = -6.94dB. A detailed analysis of the duty cycle timing is provided in the Theory of Operation accompanying the application for certification. 7.5.3.3 Measurement Results Table 7.5.3.3-1: 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 2728.8 46.71 46.71 H -3.60 43.11 36.17 74.0 54.0 30.9 17.8 2728.8 46.45 46.45 V -3.60 42.85 35.91 74.0 54.0 31.2 18.1 5457.6 48.41 48.41 H 3.82 52.23 45.29 74.0 54.0 21.8 8.7 5457.6 47.91 47.91 V 3.82 51.73 44.79 74.0 54.0 22.3 9.2 Middle Channel 2748.6 44.20 44.20 H -3.55 40.65 33.71 74.0 54.0 33.4 20.3 2748.6 44.25 44.25 V -3.55 40.70 33.76 74.0 54.0 33.3 20.2 High Channel 2765.4 45.12 45.12 H -3.51 41.61 34.67 74.0 54.0 32.4 19.3 2765.4 44.81 44.81 V -3.51 41.30 34.36 74.0 54.0 32.7 19.6 ACS Report: 15-0533.W06.1B Advanced Compliance Solutions Page 20
