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 Innovation, Science, and Economic Development Canada's Radio Standards Specification RSS-247 Certification for modular approval.

1.2 Product description

The Itron OW1 is a communications module which includes a 902.4 MHz to 927.6 MHz transmitter. The module operates on DC voltage which is supplied by a host device.

This test report documents the compliance of the 902.4 MHz to 927.6 MHz transceiver mode of operation.

1.3 Test Methodology and Considerations
All modes of operation, including all available data rates, were evaluated for each mode. The data presented in this report represents the worst case where applicable. A single test sample was not capable of supporting all modulation formats in test mode, therefore multiple samples were used to evaluate the compliance of all available modulation formats.

For radiated emissions the EUT was evaluated in three orthogonal orientations for each modulation. The worst case orientation was the Y-orientation for the FSK modulation and Zorientation for the OFDM and DSSS modulations. See test setup photos for more information. All data rates were evaluated for worst case operation for each modulation format. The worst case data rates evaluated were FSK 50kbps, OFDM 600kbps, and DSSS 12.5kbps.

For AC power line conducted emissions the EUT was evaluated with a commercially available wall wart power supply.

For RF conducted emissions, the EUT was modified with a temporary u.fl connector for coupling to the measurement equipment.

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.

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 electroplated 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 C63.10.

2.4 Conducted Emissions Test Site Description
The AC mains conducted EMI site is located in the main EMC lab. It consists of an 8' x 8' solid aluminum horizontal ground reference plane (GRP) bonded every 3" to an 8' X 8' vertical ground plane.
The site is of sufficient size to test table top and floor standing equipment in accordance with section 6 of ANSI C63.10.

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 OW1 utilizes a monopole antenna connected to the module via a cable using specialized connectors, therefore satisfying the requirements of Section 15.203. The antenna gain is 2.8dBi.
7.2 Power Line Conducted Emissions ­ FCC 15.207, ISED Canada: RSS-Gen 8.8
7.2.1 Measurement Procedure
ANSI C63.10 was the guiding document 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 Measurement Results

7.4 Channel Usage Requirements 7.4.1 Carrier Frequency Separation ­ FCC 15.247(a)(1) ISED Canada: RSS-247 5.1(2)

7.4.1.1 Measurement Procedure

The RF output port of the EUT was directly connected to the input of the spectrum analyzer using suitable attenuation. The span of the spectrum analyzer was set wide enough to capture two adjacent peaks. The RBW was set to approximately 30% of the channel spacing and adjusted as necessary to best identify the center of each channel. The VBW was set > RBW.

7.4.4 20dB / 99% Bandwidth - FCC 15.247(a)(1)(i) ISED Canada: RSS-247 5.1(3)

7.4.4.1 Measurement Procedure

The RF output port of the EUT was directly connected to the input of the spectrum analyzer using suitable attenuation. 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 marker delta and ndB down measurement functions of the analyzer were 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.

7.5.3 Radiated Spurious Emissions - FCC 15.205, 15.209;ISED Canada RSS-Gen 8.9/8.10

7.5.3.1 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 3MHz respectively.
The EUT was caused to generate a continuous modulated carrier on the hopping channel.
Each emission found to be in a restricted band was compared to the applicable radiated emission limits.
