1     GENERAL

1.1    Purpose

The purpose of this report is to demonstrate compliance with Part 15 Subpart C of the FCC’s
Code of Federal Regulations and Industry Canada’s Radio Standards Specification RSS-210 for
a class II permissive change.

The purpose of this class II permissive change is to add new antenna types to the 900 MHz LAN
frequency hopping spread spectrum radio.

1.2    Product description

The AMI3 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 board
contains (1) 900 MHz LAN frequency hopping spread spectrum radio and (1) 2.4 GHz direct
sequence spread spectrum Zigbee radio. This report addresses the 900 MHz LAN radio only.

1.3   Test Methodology and Considerations

The antennas included in this filing are connected to the meter via an adhesive patch antenna.
The intention of the patch antenna is to couple to the integral meter antenna over-the-air. The
coupled signal is then to be routed, via coax, to the antennas described in this filing.

Only model C2SO was evaluated as it represents worst case. All available data rates were
evaluated with worst case data provided in this report.

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:

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:

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: Section 15.203

The low profile radome, stub, and whip antennas are connected to the host device via an
adhesive coupling patch antenna. Professional installation is utilized.

7.2      Radiated Spurious Emissions (Restricted Bands) - FCC Sec. 15.205 IC: RSS-210 2.5

7.2.1      Measurement Procedure

Radiated emissions tests were made over the frequency range of 30MHz to 10GHz, 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 and average measurements
were made with RBW and VBW of 1 MHz and 3 MHz respectively.

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.

All available data rates were evaluated with worst case data provided.

AF        =      Antenna Factor
CA        =      Cable Attenuation
AG        =      Amplifier Gain
DC        =      Duty Cycle Correction Factor

Example Calculation: Peak

Corrected Level: 51.13 - 3.79 = 47.34dBuV/m
Margin: 74dBuV/m – 47.34dBuV/m = 26.7dB

Example Calculation: Average

Corrected Level: 44.86 - 3.79 – 0 = 41.07dBuV
Margin: 54dBuV – 41.07dBuV = 12.9dB


8     CONCLUSION

In the opinion of ACS, Inc. the CN2SO, CN2SOD, C2SOD, and C2SO, manufactured by Itron
Electricity Metering, Inc. meets the requirements of FCC Part 15 subpart C and Industry
Canada’s Radio Standards Specification RSS-210 for the additional antennas.
