Model: CVSOR-A FCC ID: SK9AMI-2A IC: 864G-AMI2A 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.

Model: CVSOR-A FCC ID: SK9AMI-2A IC: 864G-AMI2A 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.

Measurements of the radiated field strength were made at a distance of 3m from the boundary of the equipment under test (EUT) and the receiving antenna. The antenna height was varied from 1m to 4m so that the maximum radiated emissions level would be detected. Radiated measurements above 30MHz and below 1GHz were made with the Spectrum Analyzer’s resolution bandwidth set to 120 KHz using a Quasi-peak detector. For frequencies above 1000MHz, peak and average measurements made with RBW of 1 MHz and VBW of 3 MHz. 7.3.2 Test Results Results of the test are given in Table 7.3-1 below: Table 7.3-1: Radiated 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 102.211 --------- 29.11 V -13.48 --------- 15.63 -------- 43.5 --------- 27.87 129.051 --------- 32.33 V -12.30 --------- 20.03 -------- 43.5 --------- 23.47 215.982 --------- 34.85 H -15.20 --------- 19.65 -------- 43.5 --------- 23.85 302.295 --------- 43.99 H -11.65 --------- 32.34 -------- 46.0 --------- 13.66 350.084 --------- 39.54 H -9.80 --------- 29.74 -------- 46.0 --------- 16.26 950.032 --------- 19.69 V 3.70 --------- 23.39 -------- 46.0 --------- 22.61 * Note: All emissions above 950.032 MHz were attenuated below the permissible limit.

The spectrum analyzer span was set to 2 to 3 times the estimated 20 dB bandwidth of the emission. The RBW was to ≥ 1% of the estimated 20 dB bandwidth. 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.

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. 7.6.2.1 Test Results All emission found were greater than 20dB down from the fundamental carrier.

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 made with RBW of 1 MHz and VBW of 3 MHz. 7.6.3.3 Test Results Table 7.6.3-1 Radiated Intentional 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 Spurious Emissions - Low Channel 2706.75 46.84 46.84 H 0.74 47.58 47.58 74.0 54.0 26.42 6.42 2706.75 47.71 47.71 V 0.54 48.25 48.25 74.0 54.0 25.75 5.75 3609 43.03 43.03 H 3.61 46.64 46.64 74.0 54.0 27.36 7.36 3609 45.19 45.19 V 3.63 48.82 48.82 74.0 54.0 25.18 5.18 Spurious Emissions - Mid Channel 2744.25 45.55 45.55 H 0.80 46.35 46.35 74.0 54.0 27.65 7.65 2744.25 46.72 46.72 V 0.60 47.32 47.32 74.0 54.0 26.68 6.68 3659 43.85 43.85 H 3.84 47.69 47.69 74.0 54.0 26.31 6.31 3659 43.47 43.47 V 3.87 47.34 47.34 74.0 54.0 26.66 6.66 Spurious Emissions - High Channel 2783.25 45.70 45.70 H 0.85 46.55 46.55 74.0 54.0 27.45 7.45 2783.25 46.61 46.61 V 0.65 47.26 47.26 74.0 54.0 26.74 6.74 4638.75 43.67 43.67 H 6.34 50.01 50.01 74.0 54.0 23.99 3.99 * The magnitude of all emissions not reported were below the noise floor of the measurement system and below the permissible limit. 7.6.3.4 Sample Calculation: RC = RU + CFT Where: CFT = Total Correction Factor (AF+CA+AG) RU = Uncorrected Reading RC = Corrected Level AF = Antenna Factor CA = Cable Attenuation AG = Amplifier Gain Example Calculation: Peak Corrected Level: 46.84+ 0.74= 47.58dBuV/m Margin: 74dBuV/m – 46.84dBuV/m = 26.42dB Example Calculation: Average Corrected Level: 46.84+ 0.74 - 0 = 47.58dBuV Margin: 54dBuV – 47.58dBuV = 6.42dB 8.0 CONCLUSION In the opinion of ACS, Inc. the CVSOR-A, manufactured by Itron Electricity Metering, Inc. meets the requirements of FCC Part 15 subpart C and Industry Canada’s Radio Standards Specification RSS-210.
