Model: GPR2 FCC ID: R7PEC6R2S3 IC: 5294A-EC6R1S3 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: 15-0160.W06.2A Advanced Compliance Solutions Page 6

Model: GPR2 FCC ID: R7PEC6R2S3 IC: 5294A-EC6R1S3 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: 10Meters 3 Meters 40Feet 7x7x4 Pit 66 Feet Figure 2.3-2: Open Area Test Site ACS Report: 15-0160.W06.2A Advanced Compliance Solutions Page 7

Model: GPR2 FCC ID: R7PEC6R2S3 IC: 5294A-EC6R1S3 7 SUMMARY OF TESTS Along with the tabular data shown below, plots were taken of all signals deemed important enough to document. 7.1 Antenna Requirement – FCC 15.203 The integral antenna is an Inverted F with 2dBi gain and cannot be removed without permanently damaging the device, therefore satisfying the requirements of Section 15.203. 7.2 Power Line Conducted Emissions – FCC 15.207; IC RSS-Gen 8.8 The EUT is a battery operated module; therefore, AC power line conducted emissions testing was not performed. 7.3 20dB / 99% Bandwidth – FCC 15.215; IC RSS-Gen 6.6 7.3.1 Measurement Procedure 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 function of the analyzer was 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. 7.3.2 Measurement Results Table 7.3.2-1: 20dB / 99% Bandwidth 20dB Bandwidth 99% Bandwidth Frequency (MHz) (kHz) (kHz) 902.3 235.512 211.033 914.8 234.852 210.713 927.5 235.172 212.593 ACS Report: 15-0160.W06.2A Advanced Compliance Solutions Page 11

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. All out of band emissions were evaluated, including any emissions at or near the band-edge. 7.5.2 Measurement Results Table 7.5.2-1: Radiated Spurious Emissions 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 902.3 MHz (Low Channel) 902 --------- 30.72 H 0.28 --------- 31.00 -------- 46.0 --------- 15.0 902 --------- 25.89 V 0.28 --------- 26.17 -------- 46.0 --------- 19.8 914.8 MHz (Middle Channel) No Emissions detected above the noise floor of the measurement system. 927.5 MHz (High Channel) 928 --------- 22.82 H 1.12 --------- 23.94 -------- 46.0 --------- 22.1 928 --------- 21.47 V 1.12 --------- 22.59 -------- 46.0 --------- 23.4 ACS Report: 15-0160.W06.2A Advanced Compliance Solutions Page 14
