INTRODUCTION
Scope
This handbook is for use solely with the equipment identified by the AFL Part Number
shown on the front cover. It is not to be used with any other equipment unless specifically
authorised by Aerial Facilities Limited. This is a controlled release document and, as such,
becomes a part of Aerial Facilities’ Total Quality Management System. Alterations and
modification may therefore only be performed by Aerial Facilities Ltd.
Purpose
AFL recommends that the installer of this equipment familiarise his/herself with the safety
and installation procedures contained within this document before installation commences.

deeper level must be performed by AFL, normally at the company’s repair facility in
Chesham, England.
This handbook has been prepared in accordance with BS 4884, and AFL’s Quality
procedures, which maintain the company’s registration to ISO 9001: 1994 and to the
R&TTE Directive of the European Parliament. Copies of the relevant certificates and the
company Quality Manual can be supplied on application to the Quality Manager.
This document fulfils the relevant requirements of Article 6 of the R&TTE Directive.
Limitation of Information Notice
This manual is written for the use of technically competent operators/service persons. No
liability is accepted by AFL for use or misuse of this manual, the information contained
therein, or the consequences of any actions resulting from the use of the said information,
including, but not limited to, descriptive, procedural, typographical, arithmetical, or listing
errors.
Furthermore, AFL does not warrant the absolute accuracy of the information contained
within this manual, or it’s completeness, fitness for purpose, or scope.
AFL has a policy of continuous product development and enhancement, and as such,
reserves the right to amend, alter, update and generally change the contents, appearance and
pertinence of this document without notice.

SAFETY CONSIDERATIONS
1.1
Earthing of Equipment
Cell Enhancers supplied from the mains must be connected to grounded outlets and earthed
in conformity with appropriate local, national and international electricity supply and safety
regulations.
1.2
Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies.
Whilst ever potentially present in any electrical equipment, such a condition would be
minimised by quality installation practice and thorough testing at:
a) Original assembly
b) Commissioning
c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies
can be dangerous because of the possibility of substantial arcing. Always switch off during
disconnection and reconnection.

1.3
RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to
AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a ‘spare’
output has been left unterminated. Either of these conditions would impair the system’s
efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would
severely mitigate against the efficient radiation of RF power. Radio frequency burns could
also be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory)
regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is
capable of producing RF field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of directional antennas
with backscreens and a strict site rule that personnel must remain behind the screen while the
RF power is on, is strongly recommended.
Where the equipment is used near power lines, or in association with temporary masts not
having lightning protection, the use of a safety earth connected to the case-earthing bolt is
strongly advised.

1.4
Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used
in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be
toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by
contact.
Products that contain beryllium are load terminations (dummy loads) and some power
amplifiers. These products can be identified by a yellow and black “skull and crossbones”
danger symbol (shown above). They are marked as hazardous in line with international
regulations, but pose no threat under normal circumstances. Only if a component containing
beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the
formation of dust. Any dust that has been created will be contained within the equipment
module as long as the module remains sealed. For this reason, any module carrying the
yellow and black danger sign should not be opened. If the equipment is suspected of failure,
or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality Department, who will give you a
Returned Materials Authorisation (RMA) number. Please quote this number on the packing
documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation
barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any
person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes
should seek medical attention.

The AFL Channel and/or Band Selective Cell Enhancers are 2-way on-band repeaters.
Various models are available to cover frequency bands from 50MHz to 3000MHz. The
principle sphere of applications is in urban areas where the topology is such that shadows
occur in the propagation pattern (for example within large buildings, conference centres,
road and rail tunnels, etc.)
The frequency bands that are passed by the Cell Enhancer are set as per the specific
customer requirements.
AFL manufacture a wide range of Cell Enhancers, configured for each customer's specific
requirements. Two basic physical variants are available, a rack mounted version to fit in a
standard 19" rack and an environmentally sealed wall mounted version which requires no
further enclosure.
This system provides 800MHz Channelised (x 24) & VHF Simplex/Duplex coverage for the
various concourses platforms and tunnels with a 12V battery backup service (for the
800MHz line amplifier) that will guarantee limited continued coverage in case of mains
power failure.
Each active module is alarm monitored with each shelf/ wall-case having a summary alarm
with a visual ‘alarm active’ indication and a door intrusion alarm included for the wall cases.
All alarms are volt-free, relay contact pairs which may be easily configured into an
RS232/modem system such that automatic remote monitoring by computer may be
achieved.

5.1.1
Bandpass Filters (02-007201 & 01-002503)
Description
The bandpass filters are multi-section designs with a bandwidth dependent upon the
passband frequencies, (both tuned to customer requirements). The response shape is
basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled,
folded combline design, and are carefully aligned during manufacture in order to optimise
the insertion loss, VSWR and intermodulation characteristics of the unit. The tuned elements
are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50Ω
load at the input and output ports.
Being passive devices, the bandpass filters should have an extremely long operational life
and require no maintenance. Should a filter be suspect, it is usually most time efficient to
replace the module rather than attempt repair or re-tuning.

3 Port Tx Hybrid Coupler (80-024203)
Description
The transmitter hybrid couplers provide isolation from unwanted reflected frequencies
to/from the leaky feeder antennas. They are specialist narrow-band 3 port devices, designed
with rejection and power handling as the main criteria. Being passive devices, the hybrid
couplers should be maintenance free over their entire lifetime and have an extremely high
MTBF figure. It is not recommended that the top cover be removed or any of the internal
components needlessly touched, since the original factory alignment/tuning would be
extremely hard to reproduce in a ‘field’ environment.

Crossband Coupler (07-005705)
5.10.1 Description
The purpose of a crossband coupler is to either combine/split transmission signals from
different parts of the frequency spectrum.
The crossband coupler fitted here, is the means by which the separate VHF and UHF
frequency band signals are mixed to form a composite RF signal.
It basically comprises of a 3 port device, two filters, one a low pass the other a high pass,
that are then mixed and fed to a common output. The couplers are built into a machined
aluminium casing having a centre screening wall between the filter sections and lid secured
by screws at frequent intervals over its perimeter to obtain a tight seal and to ensure linearity
and stability of response.

6dB Power Monitor (07-014002)
5.11.1 Description
The purpose of these couplers is to tap off known portions (usually 3-30dB) of RF signal
from transmission lines, either resistively or by induction, and to combine them, for
example through splitter units for different purposes (alarms/monitoring etc.), whilst
maintaining an accurate 50Ω load to all ports/interfaces throughout the specified frequency
range. They are formally known as directional couplers as they couple power from the RF
mainline in one direction only.
Various constructional techniques are used depending on the specification required. These
include microstrip, stripline, coaxial cable and capacitive types.

2-Port RF Isolator (08-930002)
5.12.1 Description
The purpose of fitting an isolator to the output of a transmitter in a multi-transmitter
environment is such that each output is afforded a degree of isolation from every other. Were
this not to be the case, two simultaneous transmissions could interfere to create
intermodulation products, especially in the non-linear power amplifier output stages of the
transmitters. Whilst this effect would not affect the intelligibility of the two original
transmissions, a further two new transmissions would be created which could themselves
cause interference to third party users.
The ferrite isolator is a ferro-magnetic device, which has directional properties. In the
forward direction, RF arriving at the input is passed to the output with minimal attenuation.
In the reverse direction, RF arriving at the output due to reflected power from a badly
matched load, or due to coupling with another transmitter, is routed into an RF load where it
is absorbed. The isolator therefore functions to prevent reflected RF energy reaching the
power amplifier where it could cause intermodulation products or premature device failure.

¼Watt 0- -30dB & 0-15dB Variable Attenuators (10-000701 & 10-000901)
5.13.1 General Application
In many practical applications for Cell Enhancers etc., the gain in each path is found to be
excessive. Therefore, provision is made within the unit for the setting of attenuation in
each path, to reduce the gain.
5.13.2 Switched Attenuators
The AFL switched attenuators are available in two different types; 0 – 30dB in 2 dB
steps, or 0 – 15dB in 1 dB steps. The attenuation is simply set using the four miniature
toggle switches on the top of each unit. Each switch is clearly marked with the
attenuation it provides, and the total attenuation in line is the sum of the values switched
in. They are designed to maintain an accurate 50Ω impedance over their operating
frequency at both input and output.

5.14.1 Description
The Gallium-Arsenide low noise amplifiers used in the unit are double stage, solid-state low
noise amplifiers. Class A circuitry is used throughout the units to ensure excellent linearity
and extremely low noise over a very wide dynamic range. The active devices are very
moderately rated to provide a long trouble-free working life. There are no adjustments on
these amplifiers, and in the unlikely event of a failure, then the complete amplifier should be
replaced. This amplifier features its own in-built alarm system which gives a volt-free relay
contact type alarm that is easily integrated into the main alarm system.

3 Stage Alarm PCB & 3 Stage Simplex Alarm PCB(12-002201 & 12-002203)
5.17.1 Description
Amplifier Alarm Boards are fitted to monitor the bias conditions of AFL Class A
amplifiers which remain constant in normal operation. Any departure from normal bias
conditions is a result of device failure, excess temperature, over-driving or oscillation
(excessive power).
In normal operation, the Class A bias circuit of the amplifier develops a constant voltage of
1.20V across the collector current setting resistor. The Amplifier Alarm Board is a window
comparator device, which is adjusted to sense a departure from this condition. Several
different alarm outputs are provided to simplify interfacing, (Relay Contact, Open
Collector, and TTL Logic Levels)
The basic version of the Alarm Board (12-002801) monitors a single amplifier stage. A
three-stage version (12-002201) is used on complex amplifiers where three separate
comparators have their outputs logically combined to a common output stage. Failure of
any one stage will activate the alarms.
Note that the alarm board has a green Light Emitting Diode located near to the centre of the
printed circuit board, which is illuminated on ‘Good’, and extinguished on ‘Alarm’. It is
therefore a simple matter to identify an active module failure, by searching for an Alarm
Board which has its green LED extinguished. A simple test of the alarm board is possible
by shorting across the monitor inputs, pins 1 and 2, 3 and 4 or across pins 5 and 6. This last
monitor input is inactive if the board has been converted to a two way alarm board. (Refer
to relevant amplifier alarm wiring diagram.)

In systems using simplex channel switching, it is necessary to be able to distinguish
between a ‘normal’ switching operation and erroneous modes where faults in the detector
circuitry may cause data errors but not necessarily fire the alarms. The simplex alarm
board is designed to differentiate between normal and spurious switching signals
There are two selectable link options on the three-way board:
LINK1 - Removed to convert to two-way alarm board.
LINK2 - Removed to isolate 0V from chassis earth.
The one way alarm board only has the 0V isolation link (LINK2) fitted.

1 & 3 Stage Alarm/Simplex/Mute PCB (12-002804 & 12-002213)
5.18.1 Description
In systems using simplex channel switching, it is necessary to be able to distinguish
between a ‘normal’ switching operation and erroneous modes where faults in the detector
circuitry may cause data errors but not necessarily fire the alarms. The simplex
alarm/mute board is designed to differentiate between normal and spurious switching

Simplex Controller PCB (12-002811)
5.19.1 Description
The Simplex controller logic PCB monitors the receiver squelch output for a signal change
and activates the supply switching for either the uplink or down link path accordingly. In
normal operation, the low level Rx path is activated, and the associated Tx path is switched
off. When a signal is detected by the Rx Squelch module, the Rx squelch output goes low
(0v), which triggers the controller logic PCB. The PCB mutes the power supply to the
opposite path Rx LNA’s and switches on the power to the output power stage. In order to
prevent the power stage noise blocking the opposite path’s low level receiver, the power
amplifier is normally muted.

Dual DC/DC Converter (13-001803)
5.20.1 Description
This unit is employed where it is necessary to derive two fixed voltage power supply rails
from some higher voltage. Typically it is used to derive 5, 8, 12 or 15V from a 24V input.
The circuit is based upon a pair of LM257 series variable voltage regulators (LM2576, 12 &
15V & LM2575, 5V), which are each capable of supplying an absolute maximum of 1.5A
output current. Note that at full output current, the dissipation of the device must remain
within design limits, bearing in mind the voltage which is being dropped across it. The
maximum allowable dissipation will also depend on the efficiency of the heatsink on which
the device is mounted.

Simplex Squelch & AF Module (17-002802)
5.21.1 Description
The difference in signal levels between the paths means that the channel modules would
latch onto any signal in the band rather than a signal at the desired channel frequency. This
is achieved, in part, to having the de-sense module, (which is controlled by the Simplex Rx
squelch unit), apply maximum attenuation (via an AGC attenuator unit) to the downlink
path, when the uplink is active.

Wide Dynamic Range (Log.) 12V AGC (17-001109, det. & 17-001201, atten.)
5.22.1 Description
The equipment is fitted with a wide dynamic range (logarithmic detector) Automatic Gain
Control (AGC) system. This is generally fitted in the Uplink path (not usually needed in the
downlink path, as the signal here is at an almost constant level), to avoid overloading the
input amplifiers should a mobile be operated very close to the unit.
The AFL wide dynamic range Automatic Gain Control system consists of two units, a
detector/amplifier and an attenuator. The logarithmic detector/amplifier unit is inserted in
the RF path on the output of the power amplifier, and the attenuator is situated in the RF
path between the 1st and 2nd stages of amplification.
Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the
RF level being delivered by the power amplifier, and when a certain threshold is reached it
begins to increase the value of the attenuator to limit the RF output to the (factory set)
threshold. Therefore overloading of the power amplifier is avoided.
The factory set threshold is 1dB below the Enhancer 1dB compression point. Some
adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is
not recommended under any circumstances to adjust the AGC threshold to a level greater
than the 1dB compression point as system degradation will occur.
The detector comprises of a 50Ω transmission line with a logarithmic amplifier which
samples a small portion of the mainline power. The sampled signal is amplified and fed to a
conventional half wave diode rectifier, the output of which is a DC voltage logarithmically
proportional to the RF input signal.
This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to
the output, which drives the attenuation control line of the corresponding AGC attenuator.
This unit is fitted at some earlier point in the RF circuit.
For small signals, below AGC onset, the output control line will be close to 12V and the
AGC attenuator will have minimum attenuation. As the signal level increases the control
line voltage will fall, increasing the attenuator value and keeping the system output level at a
constant value.
The AGC onset level is adjusted by the choice of sampler resistor R1 and by the setting of
potentiometer VR1, (factory set @ time of system test) do not adjust unless able to monitor
subsequent RF levels.
The attenuator comprises a 50Ω P.I.N diode, voltage-variable attenuator with a range of 3 to
30dB. The attenuation is controlled by a DC voltage which is derived from the associated
AGC detector unit. Note that the log detector module is used with an associated controller
board, in the duplex shelves for detecting the presence of signals to be muted/amplified.

5.23.3 900MHz Programming Procedure
Check that the required downlink and uplink frequencies fall within the operational band limits
of the Cell Enhancer.
For each Downlink and Uplink channel frequency, subtract the appropriate synthesiser offset
frequency from the required operational frequency and record the resulting local oscillator
frequencies.
Divide each Downlink and Uplink local oscillator frequency by the synthesiser channel spacing
and check that the result is an integer (ie: no remainder).
If the synthesiser division ratio is not an integer value, check the required operational frequency
and repeat the calculation checking for mistakes.
Convert the required local oscillator frequency to synthesiser programming switch state patterns
according to the following table.
NOTE: Ensure that the correct column is used from the table below according to the synthesiser
channel spacing of the particular channel modules fitted to the Cell Enhancer.

Channel Selective Modules (17-009127 UHF, & 17-009135 VHF)
5.24.1 Description
The channel selectivity module is employed when the Cell Enhancer requirement dictates
that very narrow bandwidths (single operating channels), must be selected from within the
operating passband. One channel selectivity module is required for each channel.
The Channel Selectivity Module is an Up/Down frequency converter that mixes the incoming
channel frequency with a synthesised local oscillator, so that it is down-converted to an
Intermediate Frequency (IF) in the upper HF range. An eight pole crystal filter in the IF
amplifier provides the required selectivity to define the operating passband of the Cell
Enhancer to a single PMR channel. The same local oscillator then converts the selected IF
signal back to the channel frequency.
Selectivity is obtained from a fixed bandwidth block filter operating at an intermediate
frequency (IF) in the low VHF range. This filter may be internal to the channel selectivity
module (Crystal or SAW filter) or an externally mounted bandpass filter, (LC or Helical
Resonator). Various IF bandwidths can therefore be accommodated. A synthesized Local
Oscillator is employed in conjunction with high performance frequency mixers, to translate
between the signal frequency and IF.
The operating frequency of each channel selectivity module is set by the programming of
channel selectivity module frequencies and is achieved digitally, via hard wired links, banks
of DIP switches, or via an onboard RS232 control module, providing the ability to remotely
set channel frequencies.
Automatic Level Control (ALC) is provided within each channel selectivity module such that
the output level is held constant for high level input signals. This feature prevents saturation
of the output mixer and of the associated amplifiers.
Alarms within the module inhibit the channel if the synthesised frequency is not locked. The
synthesiser will not usually go out of lock unless a frequency far out of band is programmed.
The channel selectivity module is extremely complex and, with the exception of channel
frequency programming within the design bandwidth, it cannot be adjusted or repaired
without extensive laboratory facilities and the necessary specialised personnel. If a fault is
suspected with any channel selectivity module it should be tested by substitution and the
complete, suspect module should then be returned to AFL for investigation.

12 & 24V Relay Boards (20-001601 & 20-001602)
5.25.1 Description
The General Purpose Relay Board allows the inversion of signals and the isolation of
circuits. It is equipped with two dual pole change-over relays RL1 and RL2, with
completely isolated wiring, accessed via screw terminals.
Both relays are provided with polarity protection diodes and diodes for suppressing the
transients caused by "flywheel effect" which can destroy switching transistors or induce
spikes on neighbouring circuits. It’s common use is to amalgamate all the alarm signals into
one, volts-free relay contact pair for the main alarm system.
Note that the board is available for different voltages (12 or 24V) depending on the type of
relays fitted at RL1 and RL2.

12V Low Voltage Battery Disconnect Module (80-061003)
5.26.1 Description
The low voltage disconnect module’s main function is to monitor the battery voltage as
the batteries discharge. When a pre-set value has been reached (usually 21.5V DC) the
unit will disconnect the batteries to prevent a ‘deep discharge’ state which, if allowed to
continue, could irreparably damage the batteries, necessitating replacement. The unit’s
other function is to regulate the battery voltage to the cell enhancer equipment to 23.5V
when in back-up mode (the terminal voltage of fully charged batteries is likely to be
higher than 27V, and therefore potentially damaging to electronics in the system).

Crystal Filters (93-980109)
5.27.1 Description
Crystal filters are fitted at the inputs and outputs of the simplex/duplex shelves (instead of
bandpass filters) in order to maximise the excellent isolation and rejection characteristics of
these narrow-band devices. It is easier to achieve close channel spacing using crystal filters,
however, due to the increased insertion losses, higher gain amplification is needed when
they are utilised.

STPS12045TV 60A Dual Diode Assembly (94-100004)
5.29.1 Description
The purpose of these dual diode assemblies is to allow two (or more) DC voltage sources to
be combined, so that the main 12 or 24 volt DC rail within the equipment is sourced from
either the mains driven flat-pack, or externally through an XLR connector on the rear panel.
The heavy-duty diodes prevent any reverse current from flowing back to their source or the
alternative supply rail. Combining diodes such as these will also be used if the equipment is
to be powered from external back-up batteries.
5.30
15V Switch-Mode PSU (96-300054)
5.30.1 Description
The power supply unit is a switched-mode type capable of supplying 15V DC at 27Amps
continuously. The amplifiers in this unit will draw approximately 20-22Amps at 24V DC,
so the PSU will be used conservatively ensuring a long operational lifetime.
No routine maintenance of the PSU is required. If a fault is suspected, then the output
voltage from the power supply may be measured on its output terminals. This is typically
set to 15.2V. The adjustment potentiometer will be found close to the DC output
terminals.
All the PSU’s used in AFL Cell Enhancers are capable of operation from either 110 or
220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or
link setting is needed by the operator.

INSTALLATION
6.1
Initial Installation Record
When this equipment is initially commissioned, please use the equipment set-up record sheet
in Appendix A. This will help both the installation personnel and AFL should these figures
be needed for future reference or diagnosis.
6.1.1
Rack Mounted Equipment
Installation will be a matter of securing each shelf into its appropriate place in the rack
cabinet, connecting all the cables (RF, DC and alarm) to their correct ports/connectors and
system testing (at the customer’s discretion) to prove the original specification. Care should
be exercised when moving the 8U chassis as the weight may surprise an operator. Power
should not be applied until all connections have been double-checked and verified.
6.1.2
Wall Mounted Equipment
The size and weight of the wall mounting enclosure(s) mean that they represent a significant
weight hazard when fitting. In the interests of safety this should be done before any
electrical, RF, or alarm connections are made.
The equipment must be located on a perpendicular, flat surface that is made from a material
suitable for bearing the weight of the whole assembly with attached cables. If the installer is
in any doubt about the suitability of a site it is recommended that he consult with an
appropriately qualified Structural Engineer.
It is important in determining the location of the units that space is allowed for access to the
front and underneath of the equipment. To enable maintenance to be carried out, the door
must be able to open fully.
The location should be served with a duct to allow the entry of cables into the equipment.
6.1.3
Electrical Connections
The power supply is connected to the equipment via an IP65 connector located on the
bottom or side surface. It is recommended that the connection is made by a qualified
electrician, who must satisfy himself that the supply will be the correct voltage and of
sufficient capacity.
All electrical and RF connection should be completed and checked prior to power being
applied for the first time.
Ensure that connections are kept clean and are fully tightened.

6.1.4
RF Connections
All RF connections are made to the cable termination, located on the bulkhead at the rear of
the equipment at floor level (rack equipment). Care must be taken to ensure that the correct
connections are made with particular attention made to the base station Tx/Rx ports. In the
event that the base transmitter is connected to the Rx output of the rack, damage to the
equipment will be done if the base station transmitter is then keyed.
Again, ensure that connections are kept clean and are fully tightened.
6.2
Commissioning
Once all connections are made the equipment is ready for commissioning.
To commission the system the test equipment detailed in Section 7.2 will be required.
Using the system diagrams and the end-to-end test specification, the equipment should be
tested to ensure correct operation.
On initial power up the system alarm indicators on the front panels of the equipment should
be checked. A red LED illuminated indicates a fault in an amplifier module that must be
investigated before proceeding with the commissioning. A green LED on the door
illuminates, to indicate that the power supply is connected and active.
In the event that any part of the system does not function correctly as expected, check all
connections to ensure that they are to the correct port, that the interconnecting cables are not
faulty and that they are tightened. The majority of commissioning difficulties arise from
problems with the interconnecting cables and connectors.
6.3
Quick Fault Checklist
All AFL equipment is individually tested to specification prior to despatch. Failure of this
type of equipment is not common. Experience has shown that a large number of fault
conditions relating to installations result from simple causes often occurring as result of
transportation, unpacking and installation. Below are listed some common problems which
have resulted in poor performance or an indicated non-functioning of the equipment.

MAINTENANCE
7.1
7.1.1
General Procedures
Basic Fault Finding
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. The System consists of modules fitted
within an 8U shelf and housed within a standard 19” rack type cabinet.
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 LED’s. 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 module must be isolated and individually tested
against the original test specification.
The amplifier units within the shelf have a green LED showing through a hole in their cover,
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.

7.1.2
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.
7.1.3
Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies
used are those transmitted by the mobile equipment.
7.1.4
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.

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.

7.3.1
Care of Modules
General Comments
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.
7.3.2
Module Removal (LNA’s, general procedure):
The following general rules should be followed to remove a module:
Remove power to the unit
Remove all visible connectors (RF, DC & alarm)
Release module retaining screws.
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).
7.3.3
Module Replacement (general):
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.
Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to be
connected first).
Replace retaining screws (if any).
Double-check all connections before applying power.
7.3.4
Power Amplifiers
1) Remove power to the unit. (Switch off @ 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.
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.
7.3.5
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
7.3.6
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 antistatic 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.
