   The purpose of this report is to demonstrate compliance with Part 15, Subpart C of the FCC’s Code of
   Federal Regulations.

   1.2 Product Description

      1.2.1 General
      The OpenWay CENTRON meter is a solid-state meter used for measuring electrical energy
      consumption. The OpenWay CENTRON meter incorporates a two-piece design combining a
      base metrology with a variety of OpenWay registers or options. The metrology portion of the
      meter contains all measurement circuitry and calibration information, while the personality
      modules contain the register functionality and communication mediums.

      The register boards contain (1) 900 MHz LAN frequency hopping spread spectrum radio and (1)
      2.4 GHz direct sequence spread spectrum Zigbee radio. These transmitters can operate
      simultaneously and inter-modulation data is presented in Section 7.6.3.

      Manufacturer Information:
      Itron Electricity Metering, Inc.
      313 North Highway 11
      West Union, SC 29696

      defects.

      Detailed photographs of the EUT are filed separately with this filing.

      1.2.2 Intended Use
      The OpenWay CENTRON meter is a solid-state meter used for measuring electrical energy
      consumption.

   1.3 Test Methodology and Considerations
   The C2SOD operates at multiple voltages from the AC mains. All input voltages were evaluated and
   in some instances only the worst case data presented in this report.

   This device is considered a composite device by definition. The 900 MHz LAN radio and the 2.4 GHz
   Zigbee radio operate under CFR 47 Part 15.247 and IC RSS-210. This report addresses the 2400
   MHz Zigbee radio only and a separate report, 08-0028-900-DSS, will be issued for the 900 MHz
   radio.

   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:

      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.

7.0 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
The C2SOD utilizes an embedded quarter wave slot antenna with an estimated gain of 0dBi.

7.2 Power Line Conducted Emissions

7.2.1 Test Methodology
ANSI C63.4 sections 6 and 7 were the guiding documents for this evaluation. Conducted emissions were
performed from 150kHz to 30MHz with the spectrum analyzer’s resolution bandwidth set to 9kHz and the
video bandwidth set to 30kHz. The calculation for the conducted emissions is as follows:

Corrected Reading = Analyzer Reading + LISN Loss + Cable Loss
Margin = Applicable Limit - Corrected Reading

7.2.2 Test Results
Results of the test are shown below in and Tables 7.2-1 through 7.2-2.

7.3 Radiated Emissions - Unintentional Radiation

7.3.1 Test Methodology
Radiated emissions tests were performed over the frequency range of 30MHz to 1 GHz. 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 were made with the
Spectrum Analyzer’s resolution bandwidth set to 120 KHz for measurements above 30MHz. Average
measurements are taken with the RBW and VBW were set to 1MHz and 10 Hz respectively for
measurements above 1000MHz.

7.3.2 Test Results
Results of the test are given in Table 7.3-1 below:

7.6 Band-Edge Compliance and Spurious Emissions

7.6.1 Band-Edge Compliance of RF Emissions

7.6.1.1 Test Methodology
The EUT was investigated at the low and high channels of operation to determine band-edge compliance.
All antenna types were evaluated. Because the upper band-edge coincides with a restricted band, band-
edge compliance for the upper band-edge was determined using the radiated mark-delta method. The
radiated field strength of the fundamental emission was first determined and then the mark-delta method
was used to determine the field strength of the band-edge emissions.

The lower band-edge compliance was determined using the marker-delta method in which the radio
frequency power that is produced by the EUT is at least 20 dB below that in the 100 kHz bandwidth within
the band that contains the highest level of desired power.

7.6.1.2 Test Results
Band-edge compliance is displayed in Table 7.6.1.2-1 and Figure 7.6.1.2-1 – 7.6.1.2-2.

7.6.2 RF Conducted Spurious Emissions

7.6.2.1 Test Methodology
The RF Conducted Spurious Emissions were measured in accordance with the FCC KDB Publication No.
558074 “Guidance on Measurements for Digital Transmission Systems (47 CFR 15.247)”. The RF output
of the equipment under test was directly connected to the input of the Spectrum Analyzer. The EUT was
investigated for conducted spurious emissions from 30MHz to 25GHz, 10 times the highest fundamental
frequency. For each measurement, the spectrum analyzer’s RBW was set to 100 kHz and the VBW was
set to 300 kHz. The peak detector and Max Hold function of the analyzer were utilized.

7.6.2.2 Test Results
In a 100 kHz bandwidth, the radio frequency power that was produced by the EUT emissions is at least
20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of desired
power. RF Conducted Emissions are displayed in Figures 7.6.2.2-1 through 7.6.2.2-6.

7.6.3 Radiated Spurious Emissions - Restricted Bands

7.6.3.1 Test Methodology
Radiated emissions tests were made over the frequency range of 30MHz to 25GHz, 10 times the highest
fundamental frequency.

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 measurements made with RBW and VBW of 1 MHz.
Average measurements were made with RBW of 1MHz and a VBW of 10Hz. The average emissions
were further corrected by applying the duty cycle correction of the EUT to the average measurements for
comparison to the average limit.

Inter-modulation data was measured and found to be below the permissible limit.

7.6.3.2 Duty Cycle Correction
For average radiated measurements, the measured level was reduced by a factor 11.37dB to account for
the duty cycle of the EUT. The packet transmissions length is 27ms. The duty cycle correction factor is
determined using the formula: 20log (27/100) = -11.37dB. A detailed analysis of the duty cycle timing is
provided in the Theory of Operation.

7.6.3.3 Test Results
Using the procedures set forth in the FCC KDB Publication No. 558074 “Guidance on Measurements for
Digital Transmission Systems (47 CFR 15.247)”, radiated spurious emissions found in the band of 30MHz
to 25GHz are reported in Table 7.6.3.3-1 to 7.6.3.3-3. Each emission found to be in a restricted band as
defined by section 15.205, was compared to the radiated emission limits as defined in section 15.209.

Model: C2SOD                                                  FCC ID: SK9AMI-3                                         IC ID: 864G-AMI3


7.6.3.4 Sample Calculation:
RC = RU + CFT
Where:
CFT     =      Total Correction Factor (AF+CA+AG)-DC (Average Measurements Only)
RU      =      Uncorrected Reading
RC      =      Corrected Level
AF      =      Antenna Factor
CA      =      Cable Attenuation
AG      =      Amplifier Gain
DC      =      Duty Cycle Correction Factor

Example Calculation: Peak
Corrected Level: 60.28+ 6.97= 67.25dBuV/m
Margin: 74dBuV/m – 67.25dBuV/m = 6.75dB

Example Calculation: Average
Corrected Level: 50.5+ 6.97-11.37= 46.1dBuV
Margin: 54dBuV – 46.1dBuV = 7.9dB


7.7 Peak Power Spectral Density- FCC Section 15.247(d)

7.7.1 Test Methodology
The power spectral density was measured in accordance with the FCC KDB Publication No. 558074
“Guidance on Measurements for Digital Transmission Systems (47 CFR 15.247)”. The emission peaks
within the pass band were located. The spectrum analyzer RBW was set to 3 kHz and VBW 10 kHz.
Span was adjusted to 500 kHz and the sweep time was calculated to be 168s (Span/3 kHz).

7.7.2 Test Results
Results are shown below in table 7.7.2-1 and figures 7.7.2-1 – 7.7.2-3:
