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

       1.2.2 Intended Use
       The AMI4 module is intended to be used in electric utility meters to provide automated meter
       reading capabilities.

   1.3 Test Methodology and Considerations
   This AMI4 module 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. Line conducted,
   unintentional and intentional radiated emissions were measured with AMI4 integrated into the multiple
   meter form factor hosts. This report addresses the 2.4 GHz Zigbee radio only. A separate report will
   be issued to address the 900 MHz LAN radio.

   The meter forms evaluated are capable of multiple input voltages. The worst case voltage was
   applied with respect to emission levels and documented where applicable.

   Radiated intermodulation products for all simultaneously transmitting radios were also evaluated for
   all host combinations and found in compliance.

   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 2.3.1-1 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 2.3.2-2 below:

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 – FCC: Section 15.203
The antenna is a quarter wave embedded slot antenna in the ground plane with a measured gain of
4.4dBi.

7.2 Power Line Conducted Emissions – FCC: Section 15.207 IC: RSS-Gen 7.2.2

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 Table2 7.2.2-1 to 7.2.2-14.

7.3 Radiated Emissions – FCC: Section 15.109 (Unintentional Radiation) IC: RSS-210 2.6

7.3.1 Test Methodology
Radiated emissions tests were performed over the frequency range of 30MHz to 12.5GHz.
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. Above 1GHz, peak and average measurements are taken with the RBW and VBW
were set to 1MHz and 3MHz respectively.

7.3.2 Test Results
Results of the test are given in Tables 7.3.2-1 – 7.3.2.7 below:

7.4 Band-Edge Compliance and Spurious Emissions

7.4.1 Band-Edge Compliance of RF Emissions - FCC Section 15.247(d) IC: RSS-210 2.6, A8.5

7.4.1.1 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 as
outlined in FCC DA 00-705. 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 band-edge measurements provided are for each meter form factor evaluated.

7.4.2 Radiated Spurious Emissions (Restricted Bands) - FCC Section 15.205 IC: RSS-210 2.6

7.4.2.1 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 and average measurements made with RBW and VBW
of 1 MHz. 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.

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.

Radiated intermodulation products were evaluated for all simultaneously operating transmitters for each
meter form factor host combination and found to be in compliance.

7.4.2.2 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 of the original filing.

7.4.2.3 Test Results
Radiated spurious emissions found in the band of 30MHz to 25GHz for each meter form are reported in
Tables 7.4.2.3-1 to 7.4.2.3-7. Emissions not reported were below the noise floor of the measurement
instrumentation.

Model: AMI4                             FCC ID: SK9AMI-4                              IC: 864G-AMI4


7.4.2.4 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: 56.77+ 2.86 = 59.63dBuV/m
Margin: 74dBuV/m – 59.63dBuV/m = 14.37dB

Example Calculation: Average
Corrected Level: 50.52+ 2.86 - 11.37 = 42.01dBuV
Margin: 54dBuV – 42.01dBuV = 11.99dB


8.0 CONCLUSION
In the opinion of ACS, Inc. the AMI4 module, manufactured by Itron Electricity Metering, Inc. meets the
requirements of FCC Part 15 subpart C and Industry Canada’s Radio Standards Specification RSS-210.
