A dedicated power supply provides all the DC needed by the whole rack, driven from the local mains supplies (identical with PSU in VHF cell enhancer rack). Alarms are provided from each active device and all are ‘looped’ to form a normally closed fail-safe alarm (locally for each shelf and globally for the whole enhancer). This loop alarm is easily configured to join any other similarly wired system. 4.2.2 Electrical Specification PARAMETER SPECIFICATION453.7500MHz465.0375MHz471.2625MHz479.8375MHz481.0375MHz485.6375MHzUHF downlink 458.7500MHz460.0375MHz470.7125MHz474.2625MHz476.8375MHzUHF frequencies:484.0375MHzUHF uplink Gain Adjustment: 0 - 30dB (in 2dB steps) Gain Adjustment: 0 – 15dB (in 1dB step) Uplink Power: 5 Carriers @ +24dBm Downlink Power: 5 Carriers @ +27dBm AGC: Fitted in all channel selective modules In-Band Spurious: Better than –13dBm (measured with 30KHz BW with max gain setting) Noise Figure: <6dB (@ maximum gain) VSWR: better than 1.5:1 Impedance: 50ȍ1 Amplifiers Alarms Fitted: (volt-free contacts/TTL) 2 PSU 4.2.3 Mechanical Specification PARAMETER SPECIFICATIONHeight: 43U Standard Eldon Vented Rack Width: 19" (482.6mm) RackDepth: 600mm Height: See shelves parts lists Width: 19" (482.6mm) Shelves:Depth: <450mm(excluding heatsinks, connectors, handles and feet) operational: -20°C to +60°C Temperaturerange: storage: -40°C to +70°C Weight: >100kg Humidity: 5 – 95% non-condensing RF Connectors: N type female Environmental protection: IP44 Supply cable: Dedicated PSU shelf supply cable

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 78 of 86 5. INSTALLATION 5.1 Initial Installation Record When this equipment is initially commissioned, please use the equipment set-up record sheet in Appendix B. This will help both the installation personnel and AFL should these figures be needed for future reference or diagnosis. 6. FAULT FINDING & MAINTENANCE 6.1 General Fault Finding Procedures In the event that the performance of the system is suspect, a methodical and logical approach to the problem will reveal the cause of the difficulty.Transmissions from the main base stations are passed though the system to the mobile radio equipment; this could be a handheld radio or a transceiver in a vehicle. This path is referred to as the downlink. The return signal path from the mobile radio equipment to the base station is referred to as the uplink. The first operation is to check the alarms of each of the active units and determine that the power supplies to the equipment are connected and active. This can be achieved remotely (via CEMS, the RS232 Coverage Enhancement Management System, if fitted), or locally with the front panel LEDs. The green LED on the front panel should be illuminated, while the red alarm indicator should be off. If an alarm is on, then that individual shelf/module must be isolated and individually tested against the original test specification. The individual amplifier units have a green LED showing through a hole in their case, which is illuminated if the unit is working correctly. If an amplifier is suspect, check the DC power supply to the unit. If no other fault is apparent use a spectrum analyser to measure the incoming signal level at the input and then after reconnecting the amplifier input, measure the output level. Consult with the system diagram to determine the expected gain and compare result. In the event that there are no alarms on and all units appear to be functioning it will be necessary to test the system in a systematic manner to confirm correct operation.
Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 79 of 86 5.2 Downlink Confirm that there is a signal at the expected frequency and strength from the base station. If this is not present then the fault may lay outside the system. To confirm this, inject a downlink frequency signal from a known source at the master site BTS input and check for output at the remote site feeder output. If a signal is not received at the output it will be necessary to follow the downlink path through the system to find a point at which the signal is lost. The expected downlink output for the given input can be found in the end-to-end test specification. 5.3 Uplink Testing the uplink involves a similar procedure to the downlink except that the frequencies used are those transmitted by the mobile equipment. 5.4 Fault repair Once a faulty component has been identified, a decision must be made on the appropriate course to carry out a repair. A competent engineer can quickly remedy typical faults such as faulty connections or cables. The exceptions to this are cable assemblies connecting bandpass filter assemblies that are manufactured to critical lengths to maintain a 50-ohm system. Care should be taken when replacing cables or connectors to ensure that items are of the correct specification. The repair of component modules such as amplifiers and bandpass filters will not usually be possible in the field, as they frequently require specialist knowledge and test equipment to ensure correct operation. It is recommended that items of this type are replaced with a spare unit and the faulty unit returned to AFL for repair. 5.5 Checking service Following the repair of any part of the system it is recommended that a full end-to-end test is carried out in accordance with the test specification and that the coverage is checked by survey. It is important to bear in mind that the system includes a radiating cable network and base stations that may be faulty or may have been damaged. 5.6 Service Support Advice and assistance with maintaining and servicing this system are available by contacting Aerial Facilities Ltd. 5.7 Tools & Test Equipment The minimum tools and test equipment needed to successfully service this AFL product are as follows:- Spectrum analyser: 100kHz to 2GHz (Dynamic range = 90dB).

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 80 of 86 5.8 General Maintenance Procedures Many of the active modules contain semiconductor devices utilising MOS technology, which can be damaged by electrostatic discharge. Correct handling of such modules is mandatory to ensure their long-term reliability. To prevent damage to a module, it must be withdrawn/inserted with care. The module may have connectors on its underside, which might not be visible to the service operative. 5.9 Module Removal (LNAs, general procedure) The following general rules should be followed to remove a module: 1 Remove power to the unit 2 Remove all visible connectors (RF, DC & alarm) 3 Release module retaining screws. 4 Slowly but firmly, pull the module straight out of its position. Take care not to twist/turn the module during withdrawal. (When the module is loose, care may be needed, as there may be concealed connections underneath). 5.10 Module Replacement (general) 1 Carefully align the module into its location then slowly push the module directly straight into its position, taking care not to twist/turn it during insertion. 2 Reconnect all connectors, RF, alarm, power etc., (concealed connectors may have to be connected first). 3 Replace retaining screws (if any). 4 Double-check all connections before applying power. 5.11 Power Amplifiers 1) Remove power to the unit. (Switch off at the mains/battery, or remove DC in connector) 2) Remove alarm wires from alarm screw terminal block or disconnect multi-way alarm connector.3) Carefully disconnect the RF input and output coaxial connectors (usually SMA) If alarm board removal is not required, go to step 5. 4) There is (usually) a plate attached to the alarm board which fixes it to the amplifier, remove its retaining screws and the alarm board can be withdrawn from the amplifier in its entirety. On certain types of amplifier the alarm board is not mounted on a dedicated mounting plate; in this case it will have to firstly be removed by unscrewing it from the mounting pillars, in most cases, the pillars will not have not have to be removed before lifting the amplifier. 5) If the amplifier to be removed has a heatsink attached, there may be several different ways it can have been assembled. The most commonly used method, is screws through the front of the heatsink to threaded screw holes (or nuts and bolts), into the amplifier within the main case. If the heatsink is mounted on the rear of the main case (e.g., against a wall in the case of wall mounted enclosures), then the fixing method for the heatsink will be from within the case, (otherwise the enclosure would have to be removed from the wall in order to remove the heatsink).When the heatsink has been removed, the amplifier may be unscrewed from the main casing by its four corner fixings and gently withdrawn.
Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 81 of 86 Fitting a new power amplifier module will be the exact reverse of the above. Note: Do not forget to apply fresh heatsink compound to the heatsink/main case joint and also between the amplifier and the main case. 5.12 Low Power Amplifier Replacement Disconnect the mains power supply and disconnect the 24V dc supply connector for the LPA. Disconnect the RF input and output cables from the LPA. Disconnect the alarm connector. Remove the alarm monitoring wires from (D type connector) pins 9 and 10. Remove the LPA module by removing the four retaining screws, replace with a new LPA module and secure it with the screws. Connect the RF cables to the LPA input and output connectors. Reconnect the wires to the alarm board connector pins 9 and 10. Reconnect the DC supply connector and turn the mains switch on. Note: Tighten SMA connectors using only a dedicated SMA torque spanner. If SMA connectors are over-tightened, irreparable damage will occur. . Do not use adjustable pliers to loosen/tighten SMA connectors.Also take care not to drop or knock the module as this can damage (or misalign in the case of tuned passive modules) sensitive internal components. Always store the modules in an environmentally friendly location 5.13 Module Transportation To maintain the operation, performance and reliability of any module it must be stored and transported correctly. Any module not installed in a whole system must be kept in an anti-static bag or container. These bags or containers are normally identified by being pink or black, and are often marked with an ESD label. Any module sent back to AFL for investigation/repair must be so protected. Please contact AFL’s quality department before returning a module.
