The safety precautions listed below represent warnings of certain dangers of which we are aware. You should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment. Read and follow all warning notices and instructions marked on the product or included in this manual before installing, servicing or operating the equipment. Retain these safety instructions for future reference. Also, all applicable safety procedures, such as Occupational, Safety, and Health Administration (OSHA) requirements, National Electrical Code (NEC) requirements, local code requirements, safe working practices, and good judgement must be used by personnel. Refer to appropriate section of the product service manual for additional pertinent safety information. Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modifications of equipment. Identify maintenance actions that require two people to perform the repair. Two people are required when: A repair has the risk of injury that would require on person to perform first aid or call for emergency support. An example would be work around high voltage sources. A second person may be required to remove power and call for emergency aid if an accident occurs to the first person. Use the National Institute of Occupational Safety and Health (NIOSH) listing equation to determine whether a one or two person lift is required when a system component must be removed and replaced in its rack. If troubleshooting the equipment while power is applied, be aware of the live circuits. DO NOT operate the transmitter of any radio unless all RF connectors are secure and all connectors are properly terminated. All equipment must be properly grounded in accordance with Motorola Standards and Guidelines for Communication Sites “R56” (6881089E50) and specified installation instructions for safe operation. Slots and openings in the cabinet are provided for ventillation. To ensure reliable operation of the product and protect it from overheating, these slots and openings must not be blocked or covered. Only a qualified technician familiar with similar electronic equipment should service equipment. Some equipment components can become extremely hot during operation. Turn off all power to the equipment and wait until sufficiently cool before touching. 10 68P80801H35-B 5/1/2002 EBTS System Manual - Vol 1 System Installation and Testing General Safety Information Human Exposure Compliance This equipment is designed to generate and radiate radio frequency (RF) energy by means of an external antenna. When terminated into a non-radiating RF load, the base station equipment is certified to comply with Federal Communications Commission (FCC) regulations pertaining to human exposure to RF radiation in accordance with the FCC Rules Part 1 section 1.1310 as published in title 47 code of federal regulations and procedures established in TIA/EIA TSB92, Report on EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines, Compliance to FCC regulations of the final installation should be assessed and take into account site specific characteristics such as type and location of antennas, as well as site accessibility of occupational personnel (controlled environment) and the general public (uncontrolled environment). This equipment should only be installed and maintained by trained technicians. Licensees of the FCC using this equipment are responsible for insuring that its installation and operation comply with FCC regulations Part 1 section 1.1310 as published in title 47 code of federal regulations. Whether a given installation meets FCC limits for human exposure to radio frequency radiation may depend not only on this equipment but also on whether the “environments” being assessed are being affected by radio frequency fields from other equipment, the effects of which may add to the level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating facilities that exist at the time the licensee’s equipment is being installed or even by equipment installed later. Therefore, the effects of any such facilities must be considered in site selection and in determining whether a particular installation meets the FCC requirements. FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter sites of various complexities may be accomplished by means of computational methods. For more complex sites direct measurement of power density may be more expedient. Additional information on the topic of electromagnetic exposure is contained in the Motorola Standards and Guidelines for Communications Sites publication. Persons responsible for installation of this equipment are urged to consult the listed reference material to assist in determining whether a given installation complies with the applicable limits. In general the following guidelines should be observed when working in or around radio transmitter sites: - All personnel should have electromagnetic energy awareness training. - All personnel entering the site must be authorized. - Obey all posted signs. - Assume all antennas are active. - Before working on antennas, notify owners and disable appropriate transmitters. - Maintain minimum 3 feet clearance from all antennas. - Do not stop in front of antennas. - Use personal RF monitors while working near antennas. - Never operate transmitters without shields during normal operation. - Do not operate base station antennas in equipment rooms. 6 8 P 8 0 8 0 1H35- B 5/1/2002 11 System Installation and Testing EBTS System Manual - Vol 1 General Safety Information For installations outside of the U.S., consult with the applicable governing body and standards for RF energy human exposure requirements and take necessary steps for compliance with local regulations.

The following description assumes such a configuration. Figures 5 shows an overall block diagram of the BR. Power is applied to the DC Power input located on the BR backplane. The DC Power input is connected if -48 VDC or batteries are used in the site. Power is applied to the BR by setting the Power Supply power switch to the ON position. Upon power-up, the BR performs self-diagnostic tests to ensure the integrity of the unit. These tests are primarily confined to the EBRC and include memory and Ethernet verification routines. After the self-diagnostic tests are complete, the BR reports any alarm conditions present on any of its modules to the site controller via Ethernet. Alarm conditions may also be verified locally using service computer and the STATUS port located on the front of the EBRC. The software resident in Flash Memory on the EBRC registers the BR with the site controller via Ethernet. Once registered, the BR software is downloaded via resident FLASH- or Ethernet and is executed from RAM. Operating parameters for the BR are included in this download. This software allows the BR to perform call processing functions. The BR operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, provides an increased channel capacity ratio of as much as 6 to 1. Both the receive and transmit signals of the BR are divided into 6 individual time slots. Each receive slot has a corresponding transmit slot; this pair of slots comprises a logical RF channel. The BR uses diversity reception for increased coverage area and improved quality. The Receiver module within the BR contains up to three receivers. Two Receivers are used with two-branch diversity sites, and three Receivers are used with three-branch diversity sites. All Receivers within a given BR are programmed to the same receive frequency. The signals from each receiver are fed to the EBRC where a diversity combining algorithm is performed on the signals. The resultant signal is processed for error correction and then sent to the site controller via Ethernet with the appropriate control information regarding its destination. The transmit section of the BR is comprised of two separate FRUs, the Exciter and Power Amplifier (PA). Several PA FRUs are available, covering different applications and power levels; these are individually discussed as applicable in later subsections. The Exciter processes the information to transmit from the EBRC in the proper modulation format. This low level signal is sent to the PA where it is amplified to the desired output power level. The PA is a continuous keyed linear amplifier. A power control routine monitors the output power of the BR and adjusts it as necessary to maintain the proper output level. 10 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios Base Radio Overview 3X RECEIVER MODULE MIXER FROM RFDS (RECEIVER ANTENNA) #1 RF IN FROM RFDS (RECEIVER ANTENNA) #2 RF IN FROM RFDS (RECEIVER ANTENNA) #3 RF IN DSP BUS LPF/ PRESELECT/ PREAMP/ IMAGE FILTER BAND PASS FILTER IF AMP BAND PASS FILTER DIGITAL ATTEN.

The processor operates at a 50-MHz clock speed. The processor controls Base Radio operation according to station software in memory. Station software resides in FLASH memory. For normal operation, the system transfers this software to non-volatile memory. An EEPROM contains the station codeplug. NOTE At BR power-up, the EBRC LED indicates a major alarm. This indication continues until BR software achieves a predetermined state of operation. Afterward, the software turns off the EXBRC LED. 6 8 P 8 0 8 0 1E35- B 5/1/2002 Base Radio Controllers EBTS System Manual - Vol 2 Enhanced Base Radio Controller Serial Communication Buses The microprocessor provides a general-purpose SMC serial management controller bus. The SMC serial communications bus is an asynchronous RS-232 interface with no hardware handshake capability. The BRC front panel includes a nine-pin, D-type connector. This connector provides a port where service personnel may connect a service computer. Service personnel can perform programming and maintenance tasks via Man-Machine Interface (MMI) commands. The interface between the SMC port and the front- panel STATUS connector is via EIA-232 Bus Receivers and Drivers. Host Processor The microprocessor incorporates 4k bytes of instruction cache and 4k bytes of data cache that significantly enhance processor performance. The microprocessor has a 32-line address bus. The processor uses this bus to access non-volatile memory and SDRAM memory. Via memory mapping, the processor also uses this bus to control other BRC circuitry. The microprocessor uses its Chip Select capability to decode addresses and assert an output signal. The eight chip-select signals select non-volatile memory, SDRAM memory, input ports, output ports, and DSPs. The Host processor... ❐ Provides serial communications between the Host Microprocessor and other Base Radio modules. ❐ Provides condition signals necessary to access SDRAM. ❐ Accepts interrupt signals from EBRC circuits (such as DSPs). ❐ Organizes the interrupts, based on hardware-defined priority ranking. ❐ The Host supports several internal interrupts from its Communications Processor Module. These interrupts allow efficient use of peripheral interfaces. ❐ The Host supports 10 Mbps Ethernet/IEEE 802.3. ❐ Provides a 32-line data bus transfers data to and from EBRC SDRAM and other BRC circuitry. Buffers on this data bus allow transfers to and from non-volatile memory, general input and output ports and DSPs. Non-Volatile Memory Base Radio software resides in 2M x 32 bits of FLASH memory. The Host Microprocessor addresses the FLASH memory with 20 of the host address bus’ 32 lines. The host accesses FLASH data over the 32-line host data bus. A host-operated chip-select line provides control signals for these transactions. The FLASH contains the operating system and application code. The system stores application code in FLASH for fast recovery from reset conditions. Application code transfers from network or site controllers may occur in a 10 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Base Radio Controllers Enhanced Base Radio Controller background mode. Background mode transfers allow the station to remain operational during new code upgrades. The data that determines the station personality resides in a 32K x eight bit codeplug EEPROM. The microprocessor addresses the EEPROM with 15 of the host address bus’ 32 lines. The host accesses EEPROM data with eight of the data bus’ 32 lines. A host-operated chip-select line provides control signals for these transactions. During the manufacturing process, the factory programs the codeplug’s default data. The BRC must download field programming data from network and site controllers. This data includes operating frequencies and output power level. The station permits adjustment of many station parameters, but the station does not store these adjustments. Refer to the Software Commands chapter for additional information. Volatile Memory Each BRC contains 8MB x 32 bits of SDRAM. The BRC downloads station software code into SDRAM for station use. SDRAM also provides short-term storage for data generated and required during normal operation. SDRAM is volatile memory. A loss of power or system reset destroys SDRAM data. The system performs read and write operations over the Host Address and Data buses. These operations involve column and row select lines under control of the Host processor’s DRAM controller. The Host address bus and column row signals sequentially refresh SDRAM memory locations. Ethernet Interface The Host processor’s Communications Processor Module (CPM) provides the Local Area Network (LAN) Controller for the Ethernet Interface. The LAN function implements the CSMA/CD access method, which supports the IEEE 802.3 10Base2 standard. The LAN coprocessor supports all IEEE 802.3 Medium Access Control, including the following: ❐ framing ❐ preamble generation ❐ stripping ❐ source address generation ❐ destination address checking The PCM LAN receives commands from the CPU. The Ethernet Serial Interface works directly with the CPM LAN to perform the following major functions: 6 8 P 8 0 8 0 1E35- B 5/1/2002 ❐ 10 MHz transmit clock generation (obtained by dividing the 20 MHz signal provided by on-board crystal) ❐ Manchester encoding/decoding of frames 11 Base Radio Controllers EBTS System Manual - Vol 2 Enhanced Base Radio Controller ❐ electrical interface to the Ethernet transceiver An isolation transformer provides high-voltage protection. The transformer also isolates the Ethernet Serial Interface (ESI) and the transceiver. The pulse transformer has the following characteristics: ❐ Minimum inductance of 75 µH ❐ 2000 V isolation between primary and secondary windings ❐ 1:1 Pulse Transformer The Coaxial Transceiver Interface (CTI) is a coaxial cable line driver and receiver for the Ethernet. CTI provides a 10Base2 connection via a coaxial connector on the board. This device minimizes the number of external components necessary for Ethernet operations. A DC/DC converter provides a constant voltage of -9 Vdc for the CTI from a 3.3 Vdc source. The CTI performs the following functions: ❐ Receives and transmits data to the Ethernet coaxial connection ❐ Reports any collision that it detects on the coaxial connection ❐ Disables the transmitter when packets are longer than the legal length (Jabber Timer) Digital Signal Processors The BRC includes two Receive Digital Signal Processors (RXDSPs) and a Transmit Digital Signal Processor (TXDSP). These DSPs and related circuitry process compressed station transmit and receive audio or data. The related circuitry includes the TDMA Infrastructure Support IC (TISIC) and the TISIC Interface Circuitry. The DSPs only accept input and output signals in digitized form. The RXDSP inputs are digitized receiver signals. The TXDSP outputs are digitized voice audio and data (modulation signals). These signals pass from the DSP to the Exciter portion of the EXBRC. DSPs communicate with the Microprocessor via an eight-bit, host data bus on the host processor side. For all DSPs, interrupts drive communication with the host. The RXDSP operates from an external 16.8 MHz clock, provided by the local station reference. The RXDSP internal operating clock signal is 150MHz, produced by an internal Phase-Locked Loop (PLL). The RXDSP accepts digitized signals from the TISIC device through the RxDSP parallel bus. The RXDSP supports a single carrier (single 3 branch receiver) digital data input. The RXDSP accesses its DSP program and signal-processing algorithms in 128k words of internal memory. The RXDSP communicates with the host bus on an 8-bit interface. Additionally, a serial control path connects the two RXDSPs and the TXDSP. The Synchronous Communications Interface (SCI) port facilitates this serial control path. 12 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Base Radio Controllers Enhanced Base Radio Controller For initialization and control purposes, the RXDSP connects to the TISIC device. The TXDSP operates at an external clock speed of 16.8 MHz, provided by the EBRC local station reference. The TXDSP internal operating clock is 150MHz, produced by an internal Phase Lock Loop (PLL). The TXDSP sends one carrier of digitized signal to the TISIC to reformat the date before sending it to the exciter. The exciter converts the digital signal to analog. The TXDSP contains its own, internal address and data memory. The TXDSP can store 128k words of DSP program and data memory. An eight-bit interface handles TXDSP-to-host bus communications. TISIC The TISIC controls internal DSP operations. This circuit provides the following functions: ❐ For initialization and control, interfaces with the RXDSP via the DSP address and data buses. ❐ Accepts a 16.8 MHz signal from Station Reference Circuitry. ❐ Accepts a 5 MHz signal, modulated with one pulse per second (1 PPS) from the site reference. ❐ Demodulates the 1 PPS from the modulated 5 MHz signal ❐ Outputs a 1 PPS signal and a windowed version of this signal for network timing alignment. ❐ Outputs a 2.1 MHz reference signal used by the Exciter and Receiver(s). ❐ Generates 15 ms and 7.5 ms ticks. (These ticks synchronize to the 1 PPS time mark. The system decodes the time mark from the site reference. Then the system routes the reference to the TXDSP and RXDSP.) ❐ Provides a 4.8 MHz reference signal. This signal is used by the Exciter to clock data into the TRANLIN ❐ Accepts differential data from the Receiver(s) (Rx through Rx3) via the interface circuitry. ❐ Transmits serial control data to the Receiver(s) (Rx through Rx3) via the serial data bus. ❐ Accepts and formats differential data from the TXDSP for transmission to the Exciter via interface circuitry. ❐ Generates the Receiver SSI (RxSSI) frame sync interrupt for the RxDSP. Station Reference Circuitry The Station Reference Circuitry is a phase-locked loop (PLL). This PLL consists of a high-stability, Voltage-Controlled, Crystal Oscillator (VCXO) and a PLL IC. GPS output from the iSC connects to the 5 MHz/1 PPS BNC connector on the BR backplane. Wiring at this connector routes signals to EXBRC station reference circuitry. The PLL compares the 5 MHz reference frequency to the 16.8 MHz VCXO output. Then the PLL generates a DC correction voltage. The PLL applies this correction 6 8 P 8 0 8 0 1E35- B 5/1/2002 13 Base Radio Controllers EBTS System Manual - Vol 2 Enhanced Base Radio Controller voltage to the VCO through an analog gate. The analog gate closes when three conditions coexist: (1) The 5 MHz tests stable. (2) The PLL IC is programmed. (3) Two PLL oscillator and reference signal output alignments occur. A loss in the 5MHz / 1PPS signal causes the control voltage enable switch to open. This complex PLL control allows the BR to maintain 16.5 MHz capability during short disconnects (of approximately one minute) of the 5 MHz / 1 PPS signal. (For example, during 5 MHz / 1 PPS cable maintenance work.) When the gate enables, the control voltage from the PLL can adjust the high-stability VCXO frequency. The adjustment can achieve a stability nearly equivalent to that of the external, 5 MHz frequency reference. The correction voltage from the PLL continuously adjusts the VXCO frequency. The VXCO outputs a 16.8 MHz clock signal. The circuit applies this clock signal to the receiver, and TISIC. The TISIC divides the 16.8 MHz signal by seven, and outputs a 2.1 MHz signal. This output signal then becomes the 2.1 MHz reference for the Exciter and Receiver(s). Input Ports One general-purpose input register provides for EBRC and station circuit input signals. The register has 16 input ports. The Host Data Bus conveys input register data to the Host Microprocessor. Typical inputs include 16.8 Station Reference Circuitry status outputs and reset status outputs. Output Ports Two general-purpose output registers distribute control signals from the Host Microprocessor to the BRC and station circuitry. One register has 32 output ports and the other register has 8 output ports. Control signal distribution occurs over the backplane. The Host Data Bus drives the output ports’ latched outputs. Typical control signals include front-panel LED signals and SPI peripheral enable and address lines. Remote Station Shutdown The EBRC contains power supply shutdown circuitry. This circuitry can send a shutdown pulse to the Base Radio Power Supply. BRC software generates the shutdown control pulse. After receiving a shutdown pulse, the power supply turns off BR power. Shut down power sources include 3.3, 5.1, 28.6 and 14.2 Vdc sources throughout the BR. Due to charges retained by BR storage elements, power supply voltages may not reach zero. The shutdown only assures that the host processor enters a power-on-reset state. A remote site uses the shutdown function to perform a hard reset of all BR modules. 14 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios Base Radio Controller Enhanced Base Radio Controller Functional Block Diagram Model CLN1653A LED CONTROL LINES HOST LATCH P0 OUT 12 BASE RADIO POWER SUPPLY EXCITER PA CTL RX1 RX2 R3 FRONT PANEL LEDS 28V P0_OUT 5MHZ_1PPS BASE RADIO INPUT 5MHZ 1PPS SYNTHESIZER IC / CIRCUITRY PHASE DETECTION/ FILTERING/ CONTROL STEARING LINE HIGH STABILITY VCXO SHUTDOWN CIRCUITRY SHUTDOWN (TO POWER SUPPLY) REMOTE STATION SHUTDOWN CIRCUITRY 16.8 MHZ SPI BUS DISCONNECT/ CONNECT CONTROL STATION REFERENCE CIRCUITRY Figure 15 6 8 P 8 0 801E35- B 5/1/2002 Enhanced Base Radio Controller Functional Block Diagram (Sheet 1 of 2) 51 800/900/1500 MHz Base Radios EBTS System Manual - Vol 2 Base Radio Controller EnhancedBase Radio Controller FRONT PANEL RESET 5MHZ 1PPS Functional Block Diagram Model CLN1653A SERIAL MANAGEMENT CONTROLLER (SMC2) EIA-232 BUS RECEIVERS/ DRIVERS STATUS PORT (9 PIN D CONNECTOR ON BRC FRONT PANEL) SCC1 ETHERNET SERIAL INTERFACE CLSN ETHERNET SERIAL INTERFACE SERIAL CONTROL DATA TO RECEIVER 2 SERIAL CONTROL DATA TO RECEIVER 3 DIFFERENTIAL TO SINGLE END RX2 SERIAL DATA DATA CLOCK 2 DIFFERENTIAL TO SINGLE END RX3 SERIAL DATA DATA CLOCK 3 ETHERNET INTERFACE SERIAL CONTROL DATA TO RECEIVER 1 DIFFERENTIAL TO SINGLE END RX1 SERIAL DATA DATA CLOCK 1 RECEIVE DIGITAL SIGNAL PROCESSOR (RX DSP 1) CD RCV RX ISOLATION TRANSFORMER TRMT TRANSCEIVER 10BASE2 COAX TX AGC TO ALL RECEIVERS AGC D[0, 23] D[0, 8:23] BUFFER/ SPLITTER A[0:5] 2.1 MHz TO EXCITER AND RECEIVERS 1 PPS TIMING, CONTROL/ SLOT TIMING/RESET SERIAL PERIPHERAL INTERFACE SPI BUS TO/FROM STATION MODULES BUFFER DIGITAL SIGNAL PROCESSING CIRCUITRY TISIC SPI BUS NETWORKED SCI HOST ADDRESS BUS EXTENDED HOST BUS BUFFERS A[10:31] HOST A[0:7] MICROPROCESSOR GPLA0, A[8,9,17,18,20:29],RAS,CAS,WE 16 16 BUFFER DRAM MEMORY 16.8MHZ HOST-DSP BUFFERED ADDRESS BUS MA[21:0] CS2 CS3 SDRAM 4M x 16 HOST-DSP BUFFERED DATA BUS BUFFER D[0:15] SDRAM 4M x 16 D[0:15] 16 16 DSP_A[31:24] BUFFER SDRAM 4M x 16 SDRAM 4M x 16 D[16:31] 16 D[16:31] D[0:31] BUFFER 16 TRANSMIT DIGITAL SIGNAL PROCESSOR (TX DSP) MD[31:0] D[0:31] BUFFER 16 16 HOST DATA BUS D[0:7] CS4 BUFFER MA[2:21] MA[0:14] MD[0:32] FLASH 1M x 16 MD[0:15] FLASH 1M x 16 50 MHZ CLOCK MD[16:31] FLASH 1M x 16 FLASH 1M x 16 P0_IN BUFFER MD[0:15] EEPROM 32k x 8 P0_OUT LATCH MD[24:31] MD[16,17,20-24,28-31] MD[16:31] P1_OUT LATCH 32 MD[24:31] NON-VOLATILE MEMORY Figure 16 52 SERIAL DATA AND CLOCK TO EXCITER HOST BUFFERED DATA BUS CS0 CS1 P0_IN STATUS BUS FROM STATION MODULES SINGLE END TO DIFFERENTIAL DSP_D[31:24] HOST BUFFERED ADDRESS BUS MA[2:21] TRANSMIT SERIAL DATA BUS EXPANDED STATUS INPUT AND OUTPUT CONTROL CIRCUITRY 40 P0_OUT/P1_OUT CONTROL BUS TO STATION MODULES Enhanced Base Radio Controller Functional Block Diagram (Sheet 2 of 2) 68P 80801E 35- B 5/ 1/ 2002 Base Radio Exciter Overview This chapter provides technical information for the Exciter (EX).

Algonquin Road, Schaumburg, IL 60196 EBTS System Manual - Vol 2 Base Radio Exciter 800 Legacy MHz Exciter – TLN3337; 900 MHz Exciter – CLN1357; 1500 MHz Exciter – TLN3428 passed through the low-pass loop filter to the 970 MHz Voltage Controlled Oscillator (VCO) circuit (1025 MHz VCO for 900 MHz BR). 970/1025 MHz Voltage Controlled Oscillator (VCO) The 970 MHz VCO (1025 MHz for 900 MHz BR, 700 MHz for 1500 MHz BR) generates the second injection frequency for the Exciter IC. The VCO requires a very low-noise DC supply voltage of +10 VDC for proper operation. The oscillator is driven by a Super Filter that contains an ultra low-pass filter. The Super Filter obtains the required low-noise output voltage for the oscillator. The output of the oscillator is tapped and sent to the VCO Feedback Filter. This feedback signal is supplied to the Synthesizer circuitry for the generation of correction pulses. The untapped output of the 970 (or 1025) MHz VCO is sent to the second LO injection circuitry. 236/237/180.6 MHz Voltage Controlled Oscillator (VCO) The 237 MHz VCO (180.6 MHz for 900 MHz BR, 236 MHz for 1500 MHz BR) provides a LO signal to Tranlin IC for the first up-conversion and for the second down-conversion of the feedback signal. The synthesizer and divide by 2 circuitry within the Tranlin IC set the first IF to 118.5 MHz (90.3 MHz for 900 MHz BR). Regulator Circuity This circuit generates three regulated voltages of +5 VDC, +10 VDC, and +11.8 VDC. All voltages are obtained from the +14.2 VDC backplane voltage. These voltages are used to power various ICs and RF devices of the Exciter. Linear RF Amplifier Stages This circuitry is used to amplify the RF signal from the Exciter IC to an appropriate level for input to the PA. Automatic Gain Control (AGC) (1500 MHz only) The Automatic Gain Control (AGC) circuit controls the output gain of the transmitter (Exciter and Power Amplifier modules) so that constant forward gain of the RF amplifier stages is maintained. This is accomplished through the comparison of feedback signals from the Power Amplifier and the first amplifier stage of the Exciter. The output of the differential amplifiers is used to adjust the Attenuator and Image Filter. 6 8 P 8 0 8 0 1E35- B 5/1/2002 Base Radio Exciter EBTS System Manual - Vol 2 Low Noise 800 MHz Exciter Low Noise 800 MHz Exciter LNODCT (Low Noise Offset Direct Conversion Transmit) 800 MHz Exciter Overview The Low Noise Exciter and the Power Amplifier (PA) provide the transmitter functions of the Generation 2 Base Radio. The Low Noise Exciter module consists of a printed circuit board, a slide in housing, and associated hardware. The Low Noise Exciter connects to the Base Radio backplane through a 96-pin DIN connector and two blindmate RF connectors. Two Torx screws on the front of the Exciter secure it to the chassis. There are no controls or indicators on the Exciter. Specifications of the transmitter circuitry, including the Exciter and PAs, are provided in the Base Radio section of the manual.

Table 3 Exciter Circuitry Circuit Low Noise IC Description • Up-converts baseband data to the transmit frequency • Down-converts the PA feedback signal to baseband • Uses a baseband Cartesian feedback loop system, necessary to obtain linearity from the transmitter and avoid splattering power into adjacent channels • Performs training functions for proper linearization of the transmitter Memory & A/D Converter Serves as the main interface between the synthesizer, Tranlin IC, A/D, and EEPROM on the Exciter, and the BRC via the SPI bus Frequency Synthesizer Circuitry • Consists of a phase-locked loop and VCO 970 MHz VCO (800 MHz BR) Provides a LO signal to the Low Noise IC, for up-conversion to the transmit frequency 90.3 MHz VCO (800 MHz BR) Provides a LO signal to Low Noise IC, for the up-conversion and for the down-conversion of the feedback signal. • Provides a LO signal to the Low Noise IC for the second up-conversion and first down-conversion of the feedback signal from the PA The mixed output becomes the LO signal for Transmit signal up- and down- conversion Regulator Circuitry Provides a regulated voltage to various ICs and RF devices located on the Exciter Linear RF amplifier Stages Amplifies the RF signal from the Exciter IC to an appropriate level for input to the PA Memory Circuitry The memory circuitry is loaded on an EEPROM on the Exciter. The EBRC performs memory read and write operations via the SPI bus. Information stored in this memory device includes the kit number, revision number, module-specific scaling, and correction factors, operations, parameters, and free-form information (scratch pad) kit number A/D Converter Circuitry Analog signals from various areas throughout the Exciter board enter the A/D converter (A/DC). The A/DC converts these analog signals to digital form. Upon request of the BRC, A/DC output signals enter the BRC via SPI lines. The Controller periodically monitors all signals. Some of the monitored signals include amplifier bias and synthesizer signals. 6 8 P 8 0 8 0 1E35- B 5/1/2002 Base Radio Exciter EBTS System Manual - Vol 2 Low Noise 800 MHz Exciter LNODCT IC Circuitry The LNODCT IC (Low Noise Offset Direct Conversion Transmit IC) is a main interface between the Exciter and BRC. The BRC’s Digital Signal Processor (DSP) sends digitized signals (baseband data) to the Exciter over the DSP data bus. The differential data clock signal serves as a 2.4 MHz reference signal to the LNODCT IC’s internal synthesizer. The LNODCT compares the reference signal with the outputs of Voltage Controlled Oscillators (VCOs). The LNODCT might sense that a VCO’s output is out of phase or off-frequency. If so, then the LNODCT sends correction pulses to the VCO. The pulses adjust VCO output, thereby matching phase and frequency with the reference. The LNODCT IC up-converts baseband data from the EBRC to the transmit frequency. The LNODCT IC also down-converts the Transmit signal from the Power Amplifier to baseband data for cartesian feedback linearization. The EBRC uses the Serial Peripheral Interface (SPI) bus to communicate with the LNODCT IC. The SPI bus serves as a general purpose, bi-directional, serial link between the EBRC and other Base Radio modules, including the Exciter. The SPI carries control and operational data signals to and from Exciter circuits. Synthesizer Circuitry The synthesizer circuit consists of the Phase-Locked Loop (PLL) IC and associated circuitry. This circuit’s controls the 970 MHz VCO signal. An internal phase detector generates a logic pulse. This pulse is proportional to the phase or frequency difference between the reference frequency and loop pulse signal. The charge pump circuit generates a correction signal. The correction signal moves up or down in response to phase detector output pulses. The correction signal passes through the low-pass loop filter. The signal then enters the 970 MHz Voltage Controlled Oscillator (VCO) circuit. 970 MHz Voltage Controlled Oscillator (VCO) For proper operation, the VCO requires a very low-noise, DC supply voltage. An ultra low-pass filter prepares the necessary low-noise voltage and drives the oscillator. A portion of the oscillator output signal enters the synthesizer circuitry. The circuitry uses this feedback signal to generate correction pulses. The 970 MHz VCO output mixes with the 90.3 MHz VCO output. The result is a Local Oscillator [LO) signal for the LNODCT IC. The LNODCT uses this LO signal to up-convert the programmed transmit frequency. The LNODCT also uses the LO signal to down-convert the PA feedback signal. 10 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Base Radio Exciter Low Noise 800 MHz Exciter 90.3 MHz Voltage Controlled Oscillator (VCO) The synthesizer within the LNODCT IC sets the 90.3 MHz signal. The 90.3 MHz VCO provides a LO signal to the LNODCT IC. The LNODCT uses this signal in up-converting and down-converting the feedback signal. Regulator Circuitry The voltage regulators generate three regulated voltages: +3 Vdc, +5 Vdc and +11.7 Vdc. The regulators obtain input voltages from the +3.3 Vdc and +14.2 Vdc backplane voltages. The regulated voltages power various ICs and RF devices in the Exciter. Linear RF Amplifier Stages The linear RF amplifiers boost the RF signal from the LNODCT IC. The RF Amplifier generates an appropriate signal level to drive the PA. 6 8 P 8 0 8 0 1E35- B 5/1/2002 11 EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios Exciter 970 MHZ VCO CIRCUITRY EXCITER IC CIRCUITRY LNODCT IC CIRCUITRY RF FEEDBACK FROM PA MODULE +10 V DC FILTER DIFFERENTIAL DATA & CLOCK FROM BRC MODULE PLD DAC LNODCT IC LO INJECTION CIRCUITRY 90.3 VCO CIRCUITRY CONTROL VOLTAGE OSCILLATOR BUFFER AMP VCO FEEDBACK OSCILLATOR BUFFER AMP REGULATOR CIRCUITRY ADDRESS DECODE, MEMORY, & A/D CONVERTER CIRCUITRY SYNTHESIZER CIRCUITRY CHIP SELECT +5.0 V FROM BACKPLANE +14.2 V FROM BACKPLANE ADDRESS BUS FROM CONTROL MODULE SPI BUS (CLOCK & DATA) FROM BACKPLANE +3 V REGULATOR (U3702) MEMORY +3 V SOURCE 2.4 MHZ BUFFER PHASE LOCKED LOOP RIN IC CHARGE PUMP LOW-PASS LOOP FILTER +11.7 V SOURCE +11.7 V REGULATOR FIN VARIOUS SIGNALS TO MONITOR A/D CONVERTER +5 V REGULATOR VCO FEEDBACK +5 V SOURCE SPI BUS TO/FROM CONTROL MODULE LINEAR RF AMPLIFIER CIRCUITRY BPF RF OUTPUT TO PA MODULE NOTE: Where two frequencies are given, frequency without parentheses applies to 800 MHz BR only and frequency with parentheses applies to 900 MHz BR only.

DC/Metering Board (Non-QUAD PA) The DC/Metering Board provides the interface between the PA and the Base Radio backplane. The preamplified/modulated RF signal is input directly from the Exciter via the Base Radio backplane. The RF input signal is applied to the input of the Linear Driver Module (LDM). The RF feedback signal is fed back to the Exciter, where it is monitored for errors. The primary function of the DC/Metering Boards is to monitor proper operation of the PA. This information is forwarded to the Base Radio Controller (BRC) via the SPI bus. The alarms diagnostic points monitored by the BRC on the PA include the following: 6 8 P 8 0 8 0 1E35- B 5/1/2002 ❐ Forward power ❐ Reflected power ❐ PA temperature sense ❐ Fan Sensor 11 Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation DC/Metering Board (QUAD PA Only) The DC/Metering Board in the QUAD Radio serves the same function as it does in other radios. However, its circuitry is modified for compatibility with the QUAD Station. As a result, its logic circuitry is operated at 3.3 VDC. In addition to the functions listed for non-QUAD versions above, the following meter points are ported to the SPI bus: ❐ A and B Currents ❐ Thermistor (for PA temperature sensing circuit on the DC/Metering Board) ❐ Voltage Variable Attenuator Circuit (900 MHz QUAD version) ❐ PA Bias Enable Circuitry (900 MHz QUAD version) Linear Driver Module 40W-800 MHz, 70W-800 MHZ and 800 MHZ QUAD PAs The Linear Driver Module (LDM) amplifies the low-level RF signal from the Exciter. The LDM consists of a two-stage cascaded Class AB amplifier, with the final stage in a parallel configuration. See Table 2 for the approximate input and output levels of the various LDMs. The LDM output is fed to the RF Splitter/DC Distribution Board via an Interconnect Board. 900 MHz PA The Linear Driver Module (LDM) amplifies the low-level RF signal from the Exciter. The LDM consists of a three-stage, cascaded, Class AB amplifier, with the first two stages configured as distributed amplifiers and the final stage in a push-pull configuration. This output is fed directly to the RF Splitter/DC Distribution Board. See Table 2 for the approximate input and output power of the 900 MHz LDM. The LDM output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board. 1500 MHz PA The Linear Driver Module (LDM) takes the low level RF signal and amplifies it. The LDM consists of a four stage, cascaded, Class AB amplifier, with the final stage configured in push-pull configuration. This output is fed directly to the RF Splitter/DC Distribution Board. See Table 2 for the approximate input and output power of the 1500 MHz LDM. 12 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation 900 QUAD PA The Linear Driver Module (LDM) amplifies the low-level RF signal from the Exciter. The LDM consists of a three stage, cascaded, Class AB amplifier, with the final stage in a parallel configuration. See Table 2 for the approximate input and output power of the 900 MHz QUAD LDM. The LDM Output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board. Interconnect Board (40W-800 MHz, 70W-800 MHz , 800 MHz QUAD and 900 MHz QUAD) The output of the LDM is applied to the Interconnect Board, which provides an RF connection to the RF Splitter/DC Distribution Board. As a separate function, area on the Interconnect Board serves as a convenient mounting location for electrolytic capacitors used for filtering the +28 VDC supply. RF Splitter/DC Distribution Board 40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUAD The RF Splitter portion of this board accepts the amplified signal from the LDM (via the Interconnect Board). The primary function of this circuit is to split the RF signal into drive signals for the LFMs. In the 40W-800 MHz PA, this circuit splits the drive signal into three separate paths to be applied to the three LFMs, where the signals will be amplified further. In the 70W-800 MHz, 800 MHz QUAD and 900 MHZ QUAD PAs, this circuit splits the drive signal into six separate paths to be applied to the six LFMs, where the signals will be amplified further. The DC Distribution portion of this board interfaces directly with the DC/ Metering Board to route DC power to the LFMs and provide PA Bias Enable (900 MHz QUAD only) 900 MHz and 1500 MHz The RF Splitter portion of this board accepts the amplified signal from the LDM. The primary function of this circuit is to split the RF signal into two separate paths. These two outputs are fed directly to two separate Linear Final modules where the RF signals will be amplified further. The DC Distribution portion of this board interfaces directly with the DC/ Metering Board to route DC power to the LFMs. 6 8 P 8 0 8 0 1E35- B 5/1/2002 13 Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation Linear Final Modules 40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUAD The RF Splitter output signals are applied directly into the LFMs for final amplification. Each LFM contains a coupler that splits the LFM input signal and feeds the parallel Class AB amplifiers that amplify the RF signals. In the 40W PA, the amplified signals are then combined on the LFM and sent directly to the RF Interconnect Board. In the 70W PA, the amplified signals are then combined on the LFM and sent directly to the Combiner Board. See Table 2 for the approximate total summed output powers of the various LFMs, before output losses. 900 MHz PA The RF signals from the outputs of the RF Splitter are applied directly into the Linear Final Module (LFM) for final amplification. Each LFM contains a branchline coupler that splits the LFM’s input signal and feeds the dual Class AB push-pull amplifiers that amplify the RF signals. The amplified signals are then combined on the LFM and sent directly to the RF Combiner circuit for final distribution. See Table 2 for the approximate total summed output power of the 900 MHz LFMs, before output losses. 1500 MHz PA The two RF signals from the outputs of the RF Splitter are input directly into the Linear Final Module (LFM) for final amplification. Each LFM contains a branchline coupler that splits the LFM’s input signal and feeds the dual Class AB push-pull amplifiers that amplify the RF signals. The amplified signals are then combined on the LFM , via a branchline coupler, and sent directly to the RF Combiner circuit for final distribution. See Table 2 for the approximate total summed output power of the 1500 MHz LFMs, before output losses. The current drains of the 1500 MHz LFMs are monitored by the A/D converter on the DC/Metering board. A voltage signal representative of the LFM current drain is sent to the BRC. A Power Amplifier alarm is generated if the signal is outside of either the upper or lower limits. RF Interconnect Board (40W- 800 MHz PA Only) The RF Interconnect Board consists of transmission line paths which route the three output signals from the LFMs to the three inputs of the RF Combiner/ Peripheral Module. Combiner Board (40W- 800 MHz, 70W- 800 MHz, 800 MHz QUAD and 900 MHz QUAD PAs) The Combiner Board combines pairs of signals into single signals, thereby combining the six signals from the LDMs into three signals. The resulting three signals are applied to the RF Combiner/Peripheral Module. 14 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation RF Combiner/Peripheral Module (40- 800 MHz, 70W- 800 MHz PAs) This module consists of two portions: an RF combiner and a peripheral module. The RF Combiner portion of the module combines the three RF signals from the RF Interconnect Board (40W- 800 MHz PA) or the Combiner Board (70W- 800 MHz PA) into a single signal using a Wilkinson coupler arrangement. Following the combiner circuit, the single combined RF signal is then passed through a directional coupler which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a single stage circulator, which protects the PA in the event of high reflected power. The peripheral portion of the module provides a power monitor circuit that monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required. Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the PA. The thermistor signal indicating excessive temperature is applied to the A/D converter and then sent to the BRC. The BRC rolls back forward power if the monitored temperature is excessive. 900 MHz PA This module consists of two parts: an RF combiner and a peripheral module. The RF combiner combines the two RF signals from each LDM into a single signal, using a branchline coupler arrangement. Then, the RF signal passes through a directional coupler which derives a signal sample of the LFMs RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/ Metering Board, as a feedback signal, thereby allowing the Exciter to accordingly adjust signal drive. Following the coupler, the power output signal is passed through a circulator, which protects the PA in the event of high reflected power. A power monitor circuit monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required. 6 8 P 8 0 8 0 1E35- B 5/1/2002 15 Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the PA. A voltage representative of the monitored temperature is sent from the A/D converter to the BRC. The BRC rolls back forward power if the monitored temperature is excessive. 1500 MHz Both LFM outputs are input into this module where they are combined, with a branchline coupler, for a single output signal. The RF signal is first coupled to the Exciter module, via the DC/Metering Board, so that it can be monitored. The RF output signal is then passed through a circulator that acts as a protection device for the PA in the event of reflected power. A power monitor circuit monitors the forward and reflected power of the output signal. This circuit provides the A/D converter on the DC/Metering board with an input signal representative of the forward or reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC module via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. The programmed forward power is set through the use of MMI commands. If the level is not within certain parameters, the BRC will issue a warning to the site controller and may shut-down the Exciter module. Reflected power is monitored in the same manner except that the BRC determines an acceptable reflected power level. The BRC calculates the reflected power through an algorithm stored in memory. If the reflected power is determined to be excessive, the forward power is rolled back. If the reflected power level is extremely excessive, the BRC will issues a shut-down command to the Exciter module. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the Power Amplifier. A voltage representative of the monitored temperature is sent from the A/D converter to the BRC. The BRC issues a cut-back command to the Exciter module if the monitored temperature is greater than 121˚ F (85˚ C). RF Combiner/Peripheral Module (800 MHz QUAD and 900 MHz QUAD) This module consists of two parts: an RF combiner and a Peripheral module. The RF combiner combines three RF signals from the Combiner Board into a single signal using a Wilkinson coupler arrangement. Following the combiner circuit, the single combined RF signal is then passed through a directional coupler, which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a dual stage circulator, which protects the PA in the event of high reflected power. 16 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation The Peripheral module provides a power monitor circuit that monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals, representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within tolerance, the BRC will issue a warning to the site controller, which, in turn, will shut down the Exciter, if required. Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is calculated as excessive, forward power is rolled back. If the VSWR calculation is exceedingly out of tolerance, the BRC issues a shut-down command to the Exciter. NOTE The Thermistor that monitors the operating temperature of the 800 MHZ QUAD and 900 MHz QUAD PAs is located on the DC/Metering Board Fan Module The PA contains a fan assembly to maintain normal operating temperature through the use of a cool air intake. The fan assembly consists of three individual fans in which airflow is directed across the PA heatsink. The current draw of the fans is monitored by the DC/Metering Board. A voltage representative of the current draw is monitored by the BRC. The BRC flags the iSC if an alarm is triggered. The PA LED on the front panel of the BRC also lights, however the PA does not shut down due to a fan failure alone. 6 8 P 8 0 8 0 1E35- B 5/1/2002 17 EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios Power Amplifier 40W - 800 MHz Power Amplifier – TLF2020 (CLF1772) Functional Block Diagram ADDRESS DECODE, MEMORY, & A/D CONVERTER CIRCUITRY LINEAR DRIVER MODULE INTERCONNECT BOARD RF SPLITTER/DC DISTRIBUTION BOARD LINEAR FINAL MODULES RF INTERCONNECT BOARD STAGE RF INPUT 50 OHM LOAD CLASS AB STAGE 2 CLASS AB DC FILTER CLK/DATA CHIP SELECT DECODE CIRCUITRY 50 OHM LOAD MEMORY CHIP SELECT SPI BUS TO/FROM BRC +28 VDC CHIP SELECT ADDRESS BUS FROM BRC FAN ASSEMBLY FAN SENSE BOARD SELECT DECODE CIRCUITRY A/D CONVERTER PA TEMP SENSE FWD PWR REF PWR TEMPERATURE SENSOR LOW-PASS FILTER 50 OHM LOAD RF OUT TO ANTENNA RF COMBINER/ PERIPHERAL MODULE 50 OHM LOAD STAGE 3 CLASS AB 50 OHM LOAD CIRCULATOR RF FEEDBACK TO EXCITER MODULE EBTS611 121701JNM Figure 6 6 8 P 8 0 801E35- B 5/1/2002 40W - 800 MHz PA Functional Block Diagram (Sheet 1 of 1) 19 EBTS System Manual - Vol 2 DC Power Supply DC Power Supply Overview This section provides technical information for the DC Power Supply (PS).

It accepts input voltages from 41VDC to 60VDC. The voltage source may be either positive or negative ground. On initial start up, the supply requires nominal 43 VDC. If the voltage drops below 41 VDC, the DC Power Supply reverts to a quiescent mode and does not supply output power. The DC Power Supply is designed for sites with an available source of DC voltage. Output voltages supplied from the DC Power Supply are 28.6 VDC, 14.2 VDC and 5.1 VDC with reference to output ground. The supply is rated for 575 Watts continuous output at up to 113˚ F (45˚ C) inlet air. At 140˚ F (60˚ C), the 28.6 VDC output lowers to 80% of maximum. The DC Power Supply consists of the Power Supply and front panel hardware. The DC Power Supply connects to the chassis backplane using an edgecard style connector.

At the BRC> prompt, type: fiel d> fc – o p la tfo r m Receiver Sensitivity Measurement: Generation 2 Base Radio 1. Verify that the R2660 is set to 810MHz and adjust the output power to a level of -50dBm. 2. Calibrate HP438A Power Meter. Refer to the HP users guide that came with the Meter. Below is a general procedure that can be followed. 2.1 Attach 8481D Power Sensor to the Sensor input on the front of the 437B. 2.2 Attach the included HP 11708A 30dB pad to the Power input on the front on the 473B. 2.3 Power on the 437B. 2.4 Connect the Power Meter to the female end of the 30dB pad extruding from the Power input. 2.5 Press the “Zero” button on the 437B. 2.6 Wait for Zeroing operation to complete. 2.7 Press “Shift-Zero” to enter the Cal value. This is listed as CF on the Power Sensor. 2.8 Wait for Cal operation to complete. 2.9 Press “Shift-Freq” to enter the Cal Factor. This is listed as Cf in a chart vs. freq on the Power Sensor. Choose the closest frequency range for the application. For 800MHz measurements, interpolate between 1.0GHz and 0.5GHz to obtain a Cf of 99.0 2.10 For measurement of iDEN or Tornado 6:1 waveforms, press “Offset” and enter 7.78dB. 6 8 P 8 0 8 0 1E35- B 5/1/2002 3. Disconnect Cable A (see Figure 7 on page -60) from the Base Radio and connect it to the Power Sensor Head. 4. Increase the power level on the R2660 until the HP 437B Power Meter reads -50dB. 5. Record the DISPLAYED power level of the R2660 as Calfactor A. 27 Troubleshooting EBTS System Manual - Vol 2 Generation 2 Single Channel BR Station Verification Procedures 6. The path loss through the cable and splitter system is Calfactor A + 50. Example: R2660 reads -44dBm HP 437B reads -50dBm Calfactor A = -44, path loss = 6dB 7. Path loss must be determined for each Antenna cable A,B,C (see Figure 7 on page -60). If comparable cables are used for all three, the path losses of all three should be the same. 8. Additional power will be added to the R2660 in the sensitivity measurement to balance out the additional path loss value. 9. Reconnect cables A,B,C (see Figure 7 on page -60) to Antenna Ports 1,2,3. 10. Set the R2660 to Frequency 810MHz and a Power level of -108dBm + path loss. Example: If your path loss was 6dB, set the R2660 to -102dBm. 11. Using the MMI commands below, issue the command to put the BR into single branch mode. If the resulting bit error rate for receiver branches 1, 2, and 3 is less than 8.00%, the receiver has passed the test. fie l d> p p c - o rxch 1 -mch n -s 1 fiel d> f req - o rxch 1 -f8 1 0 fie l d> en a ble - or x ch 1 -s o ff fiel d> e n a ble - or x ch 1 -d b r 1 -s o n fie l d> p p r - o rxch1 -a 1 0 0 -r 1 fie l d> en a ble - or x ch 1 -s o ff fiel d> e n a ble - or x ch 1 -d b r 2 -s o n fie l d> p p r - o rx ch1 -a 1 0 0 -r 1 (skip this step if the system is configured for 2 Branch Diversity) fie l d> e n a ble - or x ch 1 -s o ff fiel d> e n a ble - or x ch 1 -d b 3 -s o n fie l d> p p r - o rx ch1 -a 1 0 0 -r 1 28 68P80801E35-B 5/1/2002 EBTS System Manual - Vol 2 Troubleshooting Generation 2 Single Channel BR Station Verification Procedures 12.

For example, the combined length of the -48 Vdc (hot) lead and the DC return lead equals the cable loop length. This would mean that a cabinet that needs 16 feet of wire between the batteries and Power Supply Rack has a total loop length of 32 feet. Determining Battery System Wire Size The wire size for the connection between the batteries and the Power Supply Rack is determined by the required wire length and the maximum allowable voltage drop. The voltage drop in the loop must be kept to below 200 mV. The wire selected should be UL approved and contain a high number of strands for flexibility. For a standard configuration, the Power Supply rack is located directly adjacent to the batteries with a cable loop length of 20 feet or less, which requires the use of a 4/0 wire. Table 3 shows recommended wire sizes for various loop lengths. Larger wire sizes may be used if the recommended sizes are not available. The recommended wire sizes are large enough to allow site expansion to a fully loaded site. Table 3 Battery System Wire Size Loop Length Wire size 20 feet 4/0 (or 250 MCM) 30 feet 350 MCM 45 feet 500 MCM Selecting Battery System Lugs Depending on the wire size used and the manufacturer of the Batteries, different wire lugs are crimped onto the power cable ends. After the wire size has been determined from Table 3, verify the manufacturer of the Batteries (Dynasty or Absolyte). Two different battery systems are offered with the EBTS. The Dynasty system is a low to medium capacity, field expandable system supplied for smaller sites or sites with minimal backup hour requirements.
