It is also used in the receive mode as a front-end to the Concentrator. The information in this manual is provided only as instructions for installation and does not entitle user to make any modifications or adjustments. 1.2 System General Description The Speed TxRx system is a computerized fully automatic radio device. It requires no human intervention after initial installation. The device includes the following parts: 1. Transmitter 2. Receiver 3. Controller 4. Antennas and cables 5. DC regulator 6. Enclosure The Transceiver receives DC power and digital data from the Repeater or Concentrator and Transmit \ Receive RF through coaxial cables which are connected to half wavelength Dipole antennas. Note: 1) The system, including transmitters, transceivers and concentrators, is installed and maintained only by qualified professional technicians. 2) The device is not adjustable by user and is supplied by manufacturer ready for installation witout provisions for adjustmant. Speed TxRx Miltel Communications Ltd.5 Chapter 2 Theory of Operation 2.1 General Description In receive mode, the Speed TxRx receives data from the Speed Tx Transmitters which are deployed near the water meter/s or from other Speed TxRx units which are in Transmit mode. The received data is processed differently whether the unit is connected to a Repeater control device or as a front-end to a Concentrator. When connected to a Repeater, the received data is processed in the Repeater’s controller. Only messages, which need to be relayed, are transferred to the Transceiver’s controller. The Controller initiates a transmission only if 30 sec. have elapsed from the previous transmission. Upon validation, the Controller switches the Transceiver to Transmit mode and transmits the data. The controller also selects the antenna from which the message will be transmitted/received. When connected as a Concentrator front-end, the Transceiver operates in receive mode. The received data is transferred to the concentrator for further processing of the meter data. Speed TxRx User Manual Miltel Communications Ltd.6 2.2 Block Diagram Description 2.2.1 General Figure 2-1 describes the block diagram of the Speed Tx Rx unit. RF is received or transmitted from either antennas upon the controller selection. Two antennas are used to improve performance in urban environment where shadowing, due to tall buildings, generates sever multipath effect. This effect can reduce the received signal by more than 30dB, thus by switching antennas periodically the transceiver improves reception. 2.2.2 Transmitter A PLL IC ( MC13176 from Motorola Semiconductors) gets the reference, 13.56MHz, from a crystal oscillator and locks the VCO output, divided by 32, to the crystal frequency. Therefore, the output frequency equals Crystal_frequency x 32 = 433.92 MHz. The message digital data from the Controller is shaped and modulates the VCO frequency. The VCO output is attenuated by a resistive Π Attenuator. A 6 pole low pass filter that rejects the harmonics, further filters the output. The output is routed through a T/R switch and a diversity switch to the output/input UHF connectors. Coaxial cables connect the half-wavelength dipole antennas with the Transceiver. All the emissions parameters are in compliance with FCC part15C specifically the limitations set by 15.231(e). When the Transceiver is in the receive mode the voltages to the Transmitter are off.

Measurement Methods and Test Results 9.1 Radiated Emission Measurement Results Measurement Method The tests were performed in Hermon Labs large (9m X 6.5m X 5.5m) full Anechoic Chamber with conductive floor (see attached drawing). The EUT was placed on a wooden turntable with the Dipole antennas and the coaxial cables. The Concentrator, which controlled the EUT via the 5-wire shielded cable, was also placed on the turntable. The Concentrator operated during all the tests. The Hydraulic antenna tower was moved such that the receive antenna was 3 meters from the EUT. The frequency range from 30MHz to 4.5GHz was investigated using an automatic HP8546A EMI receiver 9KHz –6.5GHz and HP85460A RF filter section. The receive antenna height was changed from 1to 4 meters, polarization was changed from Vertical to Horizontal and the turntable was rotated 360 0 . The following table lists frequencies at which emissions were measured using an average detector (as per 2.231(b)(2)). Limits Limit for fundamental was used as per 15.231(e): 4400μμV/m or 72.8dB μV/m. Limits for spurious emissions were used as per 15.209 for restricted bands. For the other bands, 15.231(e) or 15.209 which ever is higher as per 15.231(b)(3). In the transmit mode, the EUT was operating in the test mode…
