Test Report

FCC ID: KCH520C Sensus 520C Meter Transmitter Unit 1 of 45 900MHz DTS EMISSIONS TEST REPORT FOR A LOW POWER TRANSMITTER I. GENERAL INFORMATION Requirement:Federal Communications Commissions Test Requirements: 15.205, 15.207, 15.209, 15.247 Applicant:Sensus Metering Systems FCC ID:!!KCH520C II. DESCRIPTION OF EQUIPMENT UNDER TEST (EUT) The Sensus FCC ID: KCH520C is a digital transmission system (DTS) operating under the requirements in FCC Part 15. The product is a water meter , part of a Cellnet network that transmits meter readings to a neighborhood hub/access point r unit owned by the utility. The transmitter sends short bursts of data as required by the network, as little as once every 84 hours, as often as once every 15 seconds. The transmit times are pre- programmed and stored in the product’s EEPROM. A lithium battery powers the EUT, the battery has an expected life of over 15 years. The 520C operates in the U.S. ISM band between 902 and 928 MHz. Transmitter Specification TX Power27.56 dBm max. Frequency of operation903.8-926.2 MHz Data Rate19.2656 Kbps in <25ms burst 6 dB bandwidth1.15 MHz Power sourcelithium battery III. TEST DATES AND TEST LOCATION Testing was performed 20-21 October 2004. All tests were performed at: Compliance Certification Services 561F Monterey Road Morgan Hill, CA 95037 T.N. Cokenias29 October 2004 EMC Consultant/Agent for Sensus Metering Systems FCC ID: KCH520C Sensus 520C Meter Transmitter Unit 2 of 45 900MHz DTS 15.203 Antenna connector requirement The antenna is permanently attached to the product. For antenna conducted tests, a unit was modified by disconnecting the printed circuit antenna and replacing it with a 50 ohm coaxial cable connection terminated at one end with an SMA connector. 15.204 Antenna description The meter transceiver uses a printed circuit folded dipole antenna: Antenna descriptionGain printed ckt antenna2.2 dBi TEST DATA and TEST PROCEDURES - CCS Laboratory Radiated Emissions Test Requirement: 15.205, 15.247 Out of Band Measurements Test Requirement: 15.247 Measurement Equipment Used: Agilent 4440A Spectrum Analyzer, 9 kHz-26.5 GHz Chase Biconolog antenna EMCO 3115 Horn antenna, 1-18 GHZ Miteq pre-amplifier, 1 – 26.5 GHz IFI High pass filter, fp = 1800 MHz Radiated emissions generated by the transmitter portion of the EUT were measured. 1. The EUT was placed on a wooden table resting on a turntable on the test site. Two water meters were connected to the appropriate ports as typical loads. The search antenna was placed 3m from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. 4. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. Test Results: Worst case results are presented. Refer to data sheets below. Restricted band emissions meet 54 dBuV/m. Other undesired emissions from the transmitter meet the -20 dBc requirement in 15.247(c).
