61-83B-50-XXX-XX UserMan page 4 of 25

Antenna System Installation

The antenna or signal distribution system consists of two branches. An uplink

branch typically uses an outdoor mounted, unidirectional gain antenna such

as a yagi and a downlink signal radiating system consisting of a network of

zero-gain whip antennas or lengths of radiating cable usually mounted inside

of the structure.

Even though the antenna system may not be supplied or installed by TX RX

Systems. The following points need to be observed because both the safety

of the user and proper system performance depend on them.

1) Antenna system installation should only be performed by qualified techni-

cal personnel.

2) The following instructions for your safety describe antenna installation

guidelines based on FCC Maximum RF Exposure Compliance require-

ments.

3) The uplink antenna is usually mounted outside and exchanges signals

with the repeater base station or donor site. It is typically mounted perma-

nently-attached to the building wall or roof. The gain of this antenna should

NOT exceed 10 dB. Only qualified personnel should have access to the

antenna and under normal operating conditions, no one should be able to

touch or approach it within 104 Centimeters (41 inches).

4) The downlink or in-building signal distribution system is connected to the

downlink booster port using coaxial cable. The distribution system may

use radiating coaxial cable or a network 1/4 wave whip antennas whose

gain does not exceed 0 dB for any radiator. These antennas should be

installed so that the user cannot approach any closer than 33 Centimeters

(13 inches) from the antenna.

GENERAL DESCRIPTION

Signal boosters extend radio coverage into areas

where abrupt propagation losses prevent reliable

communication. No frequency translation (conver-

sion) occurs with this device. Signal Booster II (SB

II) is a broadband, bi-directional signal booster

available in a variety of configurations as shown in

Table 1. The product model number is used to

describe each configuration available. This manual

details the installation and operation of the 61-83B-

50-XXX-XX series of boosters.

The system can be ordered in one of three maxi-

mum gain configurations including Full Gain (+80

dB gain max), Medium Gain (+60 dB gain max),

and Low Gain (+45 dB max gain). The maximum

gain of the system is determined by the exact type

of cards plugged into the low and mid level slots as

shown in the block diagrams at the back of this

manual. The maximum gain of the uplink or down-

link branch is adjustable and can be setup inde-

pendently. In addition, the gain of each branch can

be reduced up to 30 dB in 0.5 dB increments via

software interface.

The bandwidth of the system is determined by the

passband of the input/output filtering. The filters

passband is determined by its physical construc-

tion. Three cabinet styles are available. The G1

suffix denotes a NEMA-4 style cabinet which is

suitable for indoor or outdoor use. The G2 suffix

denotes a stainless steel NEMA-4X style cabinet

suitable for corrosive environments such as salt air

and the RM suffix a rack mount version which is

intended for indoor mounting only.

UNPACKING

It is important to report any visible damage to the

carrier immediately. It is the customer's responsi-

bility to file damage claims with the carrier within a

short period of time after delivery (1 to 5 days).

Care should be taken when removing the unit from

the packing box to avoid damage to external heat-

sink fins. Use caution because the heatsink fins

can have somewhat sharp corners. Signal Booster

II (SB II) weighs about 85 lbs. so use enough peo-

ple when lifting the unit.

INSTALLATION

The following sections discuss general consider-

ations for installing the booster. All work should be

performed by qualified personnel in accordance

with local codes.

Location

The layout of the signal distribution system will be

the prime factor in determining the mounting loca-

tion of Signal Booster II. However, safety and ser-

viceability are also key considerations. The unit

should be located where it cannot be tampered

with by the general public, yet is easily accessible

to service personnel. Also consider the weight of

the unit and the possibility for injury if the unit

should become detached from its mounting sur-

faces for any reason.

Although signal boosters can operate for years

without being attended to, the unit will need to be

accessed by service personnel with troubleshoot-

ing equipment, such as digital multimeters and

spectrum analyzer or a laptop computer from time

to time. The location of the power source will also

have a bearing on the mounting location. SB II

uses external heat sinks and needs to be mounted

where there can be an unobstructed air flow over

the heat sinks fins. The SB II cabinet will stay warm

during normal operation so in the interest of equip-

ment longevity, avoid locations that carry hot

exhaust air or are continually hot.

Mounting

Figure 1 shows mounting hole dimensions and

layout for the cabinet. Mount the cabinet using 3/8”

(10 mm) diameter steel bolts (not supplied). We

recommend flat washers on both ends and a lock

washer under the nut. Nut and bolt mounting is

preferred to the use of lag bolts. Use backer blocks

where necessary to spread the force over a larger

surface area. In areas of known seismic activity,

additional devices such as tether lines may be nec-

essary.

Because TX RX Systems, Inc. cannot anticipate all

the possible mounting locations and structure

types where these devices will be located, we rec-

ommend consulting local building inspectors, engi-

neering consultants or architects for advice on how

to properly mount objects of this type, size and

weight in your particular situation.

It is the cus-

tomer’s responsibility to make sure these

devices

are mounted safely and in compliance with local

building codes.

CONNECTIONS

All cabling connections to the booster should be

made and checked for correctness prior to power-

ing up the system.

AC Line

Signal Booster II is designed to be hard-wired to

110 single phase AC lines at 50 - 60 Hz (see Fig-

ures 2 and 3). An AC line filter is provided for this

purpose. There is a hole provided in the cabinet

bottom-wall for bringing in the AC line. Fasten

quick connect plugs to each wire of the incoming

AC line, then connect the ground wire and hot wire

to the respective pins on the top of the AC line filter

assembly. Refer to the photo shown in figure 3.

The output of the AC line filter is wired into the

switch box which also contains a dual convenience

outlet for running test equipment. Use conduit for

running the AC line into the SBII cabinet and use

#14 gauge or large conductors.

Backup DC Power

SB II may be run on a DC power source that can

supply 24 to 27 volts DC at 2.5 amps (see Figures

2 and 4). This source should be equipped with a

fast-acting 3 Amp fuse. A DC line filter is provided

for making the connection inside the unit. There is

a hole provided in the cabinet bottom-wall for bring-

ing in the DC supply. Fasten spade lugs to each

wire of the incoming DC and then connect to the

respective pins on the DC line filter assembly.

Refer to the photo shown in figure 4. Use #16 or

#18 gauge wire for this connection. The power sys-

tem in SB II automatically switches to this backup

DC input when the AC supply fails for any reason

including a power outage or intentional disconnec-

tion.

It is not necessary that this connection be made for

normal operation on the AC line.

Alarm Terminals (Form-C contacts)

Two sets of contacts are provided to monitor the

general operating condition of SB II and are

intended for connection to a supervisory system.

See figure 2.

One set changes state when the AC power supply

shuts down for any reason and the unit switches to

operation on the backup DC power system. The

other set of contacts changes state when any of a

number of fault conditions arises within the elec-

tronics such as current drain outside of the

expected operating range in some module.

61-83B-50-XXX-XX UserMan page 11 of 25

A six-terminal strip is provided for the interface and

uses screw terminals for ease of connection. Route

the alarm wires through one of the access holes in

the bottom of the box, strip about 3/16” of insula-

tion from each end, loosen the screw terminal,

insert and retighten. Use #20 or #22 gauge insu-

lated wire. Use of these terminals is optional. SB II

also has a number of status LEDs built-in to indi-

vidual modules to indicate a fault condition.

RF Connections

N(F) bulkhead connectors are provided on the bot-

tom of the cabinet for connection to the signal dis-

tribution system. Be sure that the correct branch of

the distribution system is connected to its corre-

sponding Uplink/Downlink connector or the system

will not work properly. Using high-quality connec-

tors with gold center pins is advised. Flexible

jumper cables made of high-quality coax are also

acceptable for connecting to rigid cable sections.

PRE-RF CONNECTION TESTS

Antenna isolation between the uplink and downlink

branches should be measured before connecting

the signal booster to the antenna system. This step

is necessary to insure that no conditions exist that

could possibly damage the signal booster and

should not be skipped for even the most thoroughly

designed system.

Note: The 80 dB gain models are fac-

tory preset to 50 dB gain and should

only be reset to a higher value after

determining the safe maximum gain

based on antenna isolation

Test Equipment

The following equipment is required in order to per-

form the pre-installation measurements.

1) Signal generator for the frequencies of interest

capable of a 0 dBm output level. Modulation is

not necessary.

2) Spectrum analyzer that covers the frequencies

of interest and is capable of observing signal

levels down to -100 dBm or better.

3) Double shielded coaxial test cables made from

RG142, RG55 or RG223 coaxial cable.

Antenna Isolation

Just like the feedback squeal that can occur when

the microphone and speaker get too close to each

other in a public address system, a signal booster

can start to self oscillate. This can occur when the

isolation between the input antenna or signal

source and the output distribution system does not

exceed the signal boosters gain by at least 15 dB.

Oscillation will reduce the effectiveness of the sys-

tem and may possibly damage the power amplifier

stages.

In general, if one or both antenna ports are con-

nected to sections of radiating coaxial cable (lossy

cable) the isolation will be more than adequate

because of the high coupling loss values that are

encountered with this type of cable. When a net-

work of antennas are used for the input and output,

this problem is much more likely. Isolation values

are relatively easy to measure with a spectrum

analyzer and signal generator.

Procedure for Measuring Antenna Isolation

1) Set the signal generator for a 0 dBm output

level at the center frequency of one of the signal

boosters passbands (770 or 800 MHz)

2) Set the spectrum analyzer for the same center

frequency and a sweep width equal to or just

slightly greater than the passband (12 MHz)

chosen in step one.

3) Connect the test leads of the signal generator

and the spectrum analyzer together using a

female barrel connector, see Figure 5. Observe

the signal on the analyzer and adjust the input

attenuator of the spectrum analyzer for a signal

level that just reaches the 0 dBm level at the top

of the graticule.

4) Referring to figure 5, connect the generator test

lead to one side of the signal distribution system

(external antenna) and the spectrum analyzer

lead to the other (internal distribution system)

and observe the signal level. The difference

between this observed level and 0 dBm is the

isolation between the sections. If the signal is

too weak to observe, the spectrum analyzer's

bandwidth may have to be narrowed and its

input attenuation reduced. Record the isolation

value. The isolation value measured should

exceed the signal booster’s gain figure by at

least 15 dB.

NOTE

Manual 7-9410-1.2 Page 12

TX RX Systems Inc. 10/21/05

61-83B-50-XXX-XX UserMan page 12 of 25

It is wise to repeat the procedure listed above for

measuring antenna isolation with the signal gener-

ator set to frequencies at the passbands edges in

order to see if the isolation is remaining relatively

constant over the complete width of the passband.

Repeat the isolation measurements at the other

passband in bi-directional systems and use the

lesser of the two values to determine the maximum

gain setting.

Increase Isolation or decrease gain?

Modification of the signal distribution system is

required to increase isolation between the up and

downlink path. This will require significant changes

that may or may not be practical from a cost or

logistical standpoint. Gain reduction may be the

only alternative but this is easy to achieve with Sig-

nal Booster II. Gain for both the uplink and down-

link path can be set from 50 to 80 dB. Here are the

steps to follow.

1) Subtract 15 dB from the measured isolation

between uplink and downlink branches of the

antenna/signal distribution system. This is the

maximum usable gain level for both the uplink

and downlink path.

2) Accessing the user menu through the front

panel, set the gain of the uplink path to the level

determined in step 1. A detailed explanation of

how to negotiate the menu system is given on

page 14.

3) Repeat step 2 for the downlink path.

NORMAL OPERATION

Power is applied to the signal booster by turning on

1) At turn-on, the four status LEDs on the front

panel glow red for about 5 seconds as the result

of entering a self-check mode.

2) The two green OLC light bars will be fully lit

along their length for approximately 5 seconds.

3) The LCD display shows the firmware revision

screen for about 5 seconds (see Figure 6).

4) After the self check is complete, the four status

lights should turn green and the light bars

should be dark unless a signal is activating OLC

action in either the uplink or downlink.

If the OLC light-bar segments on both the Uplink

and Downlink display light-up and pulse on and off

every 1 to 3 seconds simultaneously, SHUT OFF

THE POWER IMMEDIATELY! The booster may

be oscillating. Disconnect the uplink and downlink

antenna connections and measure the isolation

between the two branches to insure there is suffi-

cient isolation. Reset the booster gain as needed.

5) The LCD display should appear similar to Fig-

ure 7 after the self check is complete.

LED Status indicators

The SB II front panel has 4 status LEDs that glow

green or red to indicate the general health of 4 sub-

systems from a DC perspective. Additionally, the

plug-in, Low-Level and Mid-Level amplifier cards

have tri-color (green-orange-red) status LEDs visi-

ble when the cabinet door is open.

FRONT PANEL LEDS:

24V: Green indicates the 24 volt DC Power system

is operating properly.

12V: Green indicates the 12 volt DC power system

is operating properly.

UL PA: Green indicates that the uplink power

amplifier is drawing current within the expected

operating range and at a safe temperature.

DL PA: Green indicates that the downlink power

amplifier is drawing current within the expected

operating range and at a safe temperature.

Module LEDS;

Mid-Level, Low-Level, Low Gain Module: Green

indicates current or device temperature within the

expected operating range. Orange indicates cur-

rent or temperature slightly out of the expected

range but the overall booster operation may still

appear normal. Red indicates a large departure

from normal current or device temperature and

booster operation is likely to be affected. See page

17 for more details about alarm operation.

Attenuator Module: Green only indicating DC

power is applied to the card.

OLC LIGHT BARS

Ideally, there should be little or no light bar activity.

Each light bar segment represents an average 3

dB of OLC gain reduction. OLC (output level con-

trol) is meant to reduce gain for transient episodes

of very strong signals. However, when OLC is

active, gain is reduced for all signals being pro-

cessed by that booster branch and that reduction

may compromise communications for weaker sig-

nals in the booster’s passband.

If more than 2 or 3 light-bar segments are lit up

more than occasionally, it is advised that the gain

of that branch be reduced. See the SET GAIN

paragraph on page 15 for details.

Front Panel Controls & the LCD Display

SB II is software directed so control of the system

is accomplished via user interface with the control

panel using the LCD display screen and the menu

select buttons, see figure 2. A flow chart showing

all of the possible user menu selections is shown in

LCD Screen

Once the boot-up sequence is completed (after

several seconds) the LCD screen will switch to the

main status display as shown in figure 7. This is the

normal display for the signal booster. The system

will return to this display from any other display if

none of the menu interface buttons are pressed

within 2 minutes. The exception is the OLC status

display which does require a button press to exit.

The main status display shows the uplink and

downlink gain in dB as well as the uplink and down-

link output level in dBm.

The last line of the main status display gives a

summary status message for the entire signal

booster. In this example “Status OK” is being dis-

played. Pressing the “ENTER” button will move

you from the main status display into the menu

selections and will permit interaction with the sys-

tem. There are two main functions available within

the software menus including configuration set-

tings and detailed status displays.

Configuration Settings

In most cases, the factory default settings are the

optimum values for adjustable parameters. The

most common setting to be changed by the sys-

tem’s technician is the gain setting. This is normally

done to compensate for varying values of antenna

isolation as outlined earlier in this manual or to

reduce excessive OLC action resulting from exces-

sive gain.

Please thoroughly study this section before making

any adjustments to the configuration values. Each

configured item is discussed in detail.

Note: Changes to configuration set-

tings do not take affect until the Main

Status screen is re-enabled. This

occurs automatically after 2 minutes

without button input or manually by

pressing the Enter/Done/Cancel but-

tons to return to the status screen.

RESTORE ORIG CONFIG

This command will restore all configured settings to

their original factory default values. SB II ships

from the factory preset to the lowest gain possible.

CALIBRATE CURRENTS

Use this command when replacing an RF amplifier.

This function automatically calibrates the current

alarm “trip” point of each amplifier in the system.

Due to manufacturing tolerances there are small

differences in current draw between amplifier

assemblies. This software function matches the

alarm sensing circuit to the respective amplifier

assembly and should be repeated whenever an

amplifier assembly is replaced.

SET GAIN

This function allows the user to electronically set

the gain of the booster in 0.5 dB increments over a

range of 30 dB. Gain can be adjusted indepen-

dently for both the uplink and downlink channels

but in most cases both uplink and downlink should

be set to the same gain value.

Know your antenna isolation before making this

adjustment. We recommend that you temporarily

disconnect both the uplink and downlink antennas

when setting the gain to avoid the possibility of

causing the unit to oscillate. After changing the set-

ting, power the unit down, reconnect the antennas

and power-up the booster.

Note: A reduction in system gain will

also result in an equal reduction in the

OLC dynamic range, refer to the sec-

tion titled “OLC” on page 16.

SET OUTPUT LEVEL

Allows the output power for the uplink and downlink

channels to be independently adjusted in 0.5 dB

increments up to +36 dBm. Note that the OLC cir-

cuitry will maintain the systems output level at the

values you have selected in this menu.

Use this function ONLY if your system is causing

some form of interference to another radio system.

You can only reduce the booster’s output power

with this command.

CHANGE GAIN CONFIGURATION

Insures proper gain readings when changing basic

booster gain by changing the type of plug-in card

assemblies.

Use of this menu is ONLY needed when converting

your stock SB II to a different gain level by chang-

ing the low level, mid-level plug-in amplifier card or

the addition of an attenuator card. It actually is a

change to the characteristics of another model.

Don’t confuse this with simple amplifier bypassing

to reduce gain. Uplink and down link can be set

independently. Choices for gain are Full, Mid or

NOTE

Low and the Enter key toggles the gain setting.

The corresponding gain level is displayed. Select

Done using the arrow keys and press enter to

return to the menu. Use the Cancel button to return

to the Status Display.

Detailed Status Screens

These items allow a detailed examination of sys-

tem components including; all amplifiers (current

draw and temperature), the power supply (voltage

level), and the OLC function (present status and

historical archive). Each item is discussed below in

detail.

AMPLIFIERS

A separate status screen is available for each

amplifier in the system. When an amplifier is

selected this function will display the present cur-

rent draw of that amp as well as its present operat-

ing temperature in degrees Celsius. In addition, a

status message will indicate if the amplifier is con-

nected and whether the amplifier is bypassed or

not bypassed. This menu selection also provides

the option of placing an amplifier in bypass or tak-

ing an amplifier out of bypass.

The current draw will be blank if an amplifier is not

connected, will display BYP if the amplifier is

bypassed, and will display ATTEN if an attenuator

card is being used in place of the amplifier card.

The power amplifier currents will nor-

mally fluctuate up to 850 ma when sig-

nals are present.

POWER SUPPLY

This function displays the real time power supply

voltages for both 24 volt and 12 volt supplies.

OLC

This screen shows the amount of attenuation pres-

ently being used by the OLC for both the uplink

and downlink channels. In addition, the percentage

of OLC presently being used is also shown.

The amount of OLC currently being

used in either the uplink or downlink

channels is also indicated by LED bar

graph displays located on the display

panel. Each segment represents 2 to

4 dB of attenuation depending on the gain setting

of the booster. The OLC bars should only be active

occasionally and no more than 3 or 4 segments

briefly lit. Constant light bar activity means the

booster gain needs to be reduced for optimum per-

formance.

The system has 60 dB of OLC

dynamic range. However, it can be

reduced when a portion of the

dynamic range is used as fixed atten-

uation to reduce system gain. The

reduction will be an equal amount. For instance, if

the gain is reduced by 20 dB then the OLC

dynamic range will also be reduced by 20 dB. In

the factory, the system gain is allowed to be no

more than 3 dB above the minimum levels of 80/

60/45 dB. But every amplifier has slightly different

gains and some have higher gains than the others.

When a system gain is more than 3 dB above the

minimum level (due to fluctuation in amplifier

gains), part of the OLC dynamic range is pro-

grammed during final calibration as fixed attenua-

tion to reduce the system gain. In the field, a user

can further adjust the system gain by setting the

“user selectable gain” lower and effectively pro-

gramming more OLC dynamic range into fixed

attenuation.

OLC DATALOG

This screen displays an OLC Datalog which is the

OLC data over the past 100 days for both uplink

and downlink branches of the system. This is a roll-

ing 100 day log with day 101 overlapping day 1

and so forth. Day zero represents the current day

while day one represents yesterday and so on. The

logged data is stored in non-volatile memory and

will not be erased when the unit is powered down.

The average OLC attenuation used when the OLC

was active is given both for individual days and

over the entire past 100 days. The percentage of

time the OLC was active is also given for both indi-

vidual days and over the past 100 days. This

archived information will permit the creation of a

user signal profile to facilitate optimum system con-

figuration and performance.

This archive feature will allow you to see if the gain

of the unit is set too high or if there are transient

episodes of strong signals perhaps desensing

other channels being amplified by the booster.

Alarms

The system continuously monitors the current draw

and operating temperature of each amplifier as

well as the voltage level of the +12 and +24 VDC

supplies. If any of these parameters exceed normal

operating levels by a factory preset percentage the

system enters an alarm condition. Notification of an

alarm condition is provided by LED indicators and

Form-C contacts available via the alarm terminal

screws.

LED INDICATORS

There are LED indicators for each amplifier in the

system as well as the +12 and +24 VDC power

supply voltages. The LED indicators for the low,

mid, and low gain amplifiers are located on the

individual plug-in module. These are tri-color LED’s

with green representing NORMAL operation,

orange representing a WARNING condition, and

red indicating a FAULT. A warning condition

occurs when the current draw of the amplifier

exceeds nominal by +/- 20%. Fault conditions

occur when the current draw exceeds +/- 30% or

the amplifiers operating temperature exceeds 80°

Celsius. The LED for the attenuator card is green

only and indicates DC power applied to the card.

The LED indicators for the power amplifiers are

located on the display panel next to the menu

select buttons and are dual color LED’s. Green

represents NORMAL operation while red indicates

a FAULT condition. Fault conditions occur when

the current draw exceeds 900 ma or falls below

200 ma. Also, whenever the amplifiers operating

temperature exceeds 95° Celsius. The power

amplifiers do not have a warning state.

The power supply LED indicators are located on

the display panel next to the menu selection but-

tons and are also dual color. Green representing

normal operation and red a fault condition. A fault

condition for the +24 VDC supply occurs whenever

the voltage potential drops below +16 VDC (30%

below nominal). Likewise, a fault for the +12 VDC

supply occurs when the potential is below +8 VDC

(30% below nominal).

FORM-C CONTACTS

Form-C contacts are available inside the cabinet

next to the power supply assembly, see figure 2.

These screw terminals are intended for connection

to the customers supervisory alarm or data acquisi-

tion system. One set of terminals supplies notifica-

PERFORMANCE SURVEY

It is a good idea to document the performance of

the system after installation so that a reference

exists for future comparisons. This information can

make troubleshooting an interference problem or

investigation of a complaint about system perfor-

mance much easier. If there are coverage prob-

lems with a system, this survey will usually reveal

them allowing corrective measures to be taken

before the system is put into routine use. The fol-

lowing is an outline of how to do such a survey.

Because the nature of each installation can be

quite different, only a broad outline is given.

1) Measure the gain of the signal booster being

careful not to exceed the maximum input level.

Figure 9 shows this being done using a signal

generator and spectrum analyzer. Record the

measured values for each passband. We rec-

ommend that a 50 ohm load be connected to

the unused RF port on the bottom of the cabinet

during the gain test.

2) The spectrum analyzer is connected to the -30

dB signal sampler port following the final output

amp. This port will allow the observation of the

amplifier output at a considerably reduced out-

put level. This decoupling value (-30 dB) needs

to be added to any measured signal value in

order to arrive at the actual signal level.

3) With a spectrum analyzer connected to the sig-

nal sampler port (see Figure 10), have person-

nel with handheld radios move to several

predetermined points and key their radios.

Record the level of these signals as observed

on the analyzer and also record the location of

the person transmitting. In this way, a map of

the systems performance can be generated.

4) For signals coming from a fixed antenna or sta-

tion, record the level of all the desired incoming

signals for future reference.

MAINTENANCE AND REPAIR

lightning strikes, failures may occur. The following

procedures may be followed for detecting a mal-

functioning unit or as part of a periodic mainte-

nance program.

1) The heatsink area should be cleared of dust

and debris.

2) Inspect the unit to see that the two power sup-

ply LED DC indicators are lit (remove any dust

or debris that may obscure the LEDs). This will

verify that DC power is flowing properly. Check

all hardware for tightness.

3) Compare system performance to initial perfor-

mance levels measured when the system was

first installed. The lack of signal can be traced

to a malfunctioning amplifier by progressive sig-

nal monitoring from the output (far end) to the

input end of the system noting the area where

the signal returns to normal level. The next

amplifier toward the output end of the system

will probably be the one that failed.

Measure the gain at any convenient frequency

in the working frequency band to verify that the

performance is still within specifications.

Power Amplifier Replacement

The SB II power amplifiers are field replaceable.

Follow the steps listed below in sequential order.

The required tools are a #1 Phillips screwdriver

and a 5/16” open-ended wrench.

Note: Power to the SB II cabinet must

be turned OFF during the power

amplifier replacement process.

1) Remove the Phillips screws which hold the

amplifier into place, refer to Figure 11. The nuts

holding the screws are pressed into the cabinet

and will remain in place when the screws are

removed.

2) Slide the amplifier towards the bottom of the

cabinet as far as it will go. This will allow the top

RF connector to clear the opening. Tilt the top

of the amplifier outwards and remove the top

RF cable at the SMA connector using the 5/16”

wrench. See Figure 12.

3) Slide the amplifier assembly towards the top of

the cabinet as far as it will go. This will allow the

bottom RF connector and grey control cable to

clear the opening. Tilt the bottom of the ampli-

fier outwards and remove the bottom RF cable

at the SMA connector and the grey control

cable. To remove the grey cable from the

socket on the amplifier it is necessary to

squeeze the top and bottom of the connector

together to release a hold down tab. When

properly squeezed the grey cable will discon-

nect easily from the amplifier. Refer to Figure

13.

4) To replace the amplifier assembly repeat steps

1 through 3 in reverse order. When replacing

the RF cables do not overtighten the SMA con-

nectors. They should be tightened just slightly

more than hand tight or to the specification of 7

in/lbs. The replacement amplifier comes with an

attached gasket which must press up against

the outside of the cabinet firmly and squarely in

order to provide a correct moisture seal.

Module Replacement

The SB II modules are field replaceable. Follow the

steps listed below in sequential order. The required

tools are a #1 Phillips screwdriver. Two thumb

screws hold each module into place.

Note: Power to the SB II cabinet must

be turned OFF during the module

replacement process except for the

amplifier modules which are “HOT”

switchable.

1) Loosen the two thumb screws which hold the

module into place. Phillips screws are incorpo-

rated into the thumbscrews and they may need

to be loosened first.

2) Grasping the two loosened thumb screws pull

the module straight out of the card cage.

3) To install the replacement module place the

module into the guide-rails of the slot and press

down firmly into place. Each type of module is

keyed uniquely to fit in only one slot within the

card cage. Once the card is seated into place

properly tighten the thumb screws.

The SB II low level and mid level amplifier stages

are field replaceable by simply removing the mod-

ule and plugging in a replacement. These modules

are HOT switchable meaning they can be swapped

without powering down the system. RF cables

attached to the modules must be removed (5/16”

wrench) prior to swapping the modules and must

be re-attached after the new module is in place.

when replacing the RF cables do not overtighten

the SMA connectors. They should be tightened just

slightly more than hand tight or to the specification

of 7 in/lbs.

Modules can be swapped between the uplink and

downlink branches for troubleshooting purposes. If

a problem exists in one branch and the problem

moves to the other branch when modules are

swapped around this indicates a defective module.

Note: After an amplifier module is

replaced use the Calibrate Currents

software function to properly set the

amplifiers alarm trip point, see page

10. Due to slight differences in compo-

nent tolerances the trip point must be

reset for any new amplifier assemblies

introduced into the system.

Display/User Interface Assembly Replacement

The SB II Display/User Interface assembly is field

replaceable. Follow the steps listed below in

sequential order. No tools are required.

Note: Power to the SB II cabinet must

be turned OFF during the display/user

interface replacement process.

1) Loosen the two thumb-nuts which hold the dis-

play/user interface assembly to the card cage.

NOTE

2) Gently tilt only the top of the assembly up from

the card cage. Keep the bottom of the assembly

in place. The bottom mounting plate (part of the

card cage) has an overhang on it to support the

display/user interface board. If the assembly is

lifted straight out the overhang it could possibly

damage the interface circuit board.

3) With the display/user interface board standing

up straight gently move it upwards while lifting it

out about an inch or two. This should allow the

overhang to clear the interface circuit board

without damage.

4) Remove the ribbon cable that connects the dis-

play/user interface assembly to the card cage,

see Figure 14.

5) To replace the display/user interface assembly

repeat steps 1 through 4 in reverse order.

Power Supply Replacement

The SB II power supply assembly is field replace-

able. Follow the steps listed below in sequential

order. The required tools are a #1 Phillips screw-

driver.

1) Turn off AC power at the junction box.

2) Disconnect the 3 conductor cable that brings

AC power to the supply from the junction box.

3) Disconnect the red and black leads from the

power supply that connect to the card cage.

4) Remove the Phillips screws that hold the power

supply mount bracket to the back plate and

remove the assembly from the cabinet.

5) Reverse steps 4 through 2 to install the replace-

ment power supply.

Duplexer / Filter Replacement

The filter assemblies are field replaceable. Follow

the steps listed below in sequential order. The

required tools are a #1 Phillips screwdriver with an

extended shaft to reach down far enough into the

unit to loosen the mounting screws.

Note: Power to the SB II cabinet must

be turned OFF during the filter

replacement process.

1) All RF cables attached to the assembly must be

removed (5/16” wrench).

2) Remove the Phillips screws that hold the

assembly mount brackets to the back plate and

remove the assembly from the cabinet.

3) Reverse steps 2 and 1 to install the replace-

ment filter. When replacing the RF cables do

not overtighten the SMA connectors. They

should be tightened just slightly more than hand

tight or to the specification of 7 in/lbs.

Card Cage Replacement

To replace the card cage follow the steps listed

below in sequential order. The required tools are a

#1 Phillips screwdriver with an extended shaft to

reach down far enough into the unit to loosen the

mounting screws.

Note: Power to the SB II cabinet must

be turned OFF during the card cage

replacement process.

1) Disconnect the display/user interface assembly.

2) Disconnect 4 cables at the backplane of the

card cage which are assessable with the dis-

play/user interface board out of the way.

3) Remove the row of Phillips screws which hold

the card cage to the back plate. There is a row

of screws at the top and bottom of the cage.

4) To install a replacement cage perform steps 3

through 1 in reverse order.

Tuning Instructions

Tuning instructions are provided in support of field

service activities. It is assumed that the procedures

listed in this manual will be carried out by a quali-

fied electronics technician observing all standard

safety practices.

The amplifier assemblies used in the model 61-

83B-50-XXX-XX signal boosters are of sufficient

bandwidth to cover the entire range of operation.

Tuning is not required. The individual filters used in

the duplexer are passive devices of rugged electri-

cal and mechanical design. They are tuned at the

factory for the original design requirements and

require no adjustment or maintenance. These

devices will stay properly tuned unless they have

NOTE

Manual 7-9410-1.2 Page 23

TX RX Systems Inc. 10/21/05

61-83B-50-XXX-XX UserMan page 23 of 25

been physically damaged or are tampered with.

Combline preselector filters provide the input and

output selectivity for the system. These filters have

a carefully shaped response curve that passes a

number of contiguous communication channels

with each filter designed to cover a 12 MHz band-

width.

TEST EQUIPMENT

A two channel network analyzer that simulta-

neously displays both transmission and reflection

is best for properly tuning a preselector. A single

channel tracking generator/spectrum analyzer

combination may be adequate but is not accurate

enough to verify factory specifications. A return

loss bridge would also be required when using a

tracking generator. Skill and experience are also

needed and the personnel doing the work should

be thoroughly familiar with the use of the network

analyzer. A Hewlett Packard 8752B or equivalent

network analyzer is recommended.

PRESELECTOR TUNING

The following is a general outline of the tuning pro-

cedure.

1) Connect test equipment as shown in Figure 15.

2) Set the analyzer to the desired center fre-

quency and desired bandwidth.

3) Loosen the tuning rod locking nuts.

4) If the preselector is severely out of tune, set the

analyzer for 10 dB/div vertical scale on the

transmission channel and alternately adjust the

tuning rods in pairs working from the center to

the end rods for maximum signal at the center

frequency. Note that for preselectors with an

odd number of rods, start with the center rod

and then move to the pairs, one on either side

of center.

5) Repeat step 4 tuning to maximize the signal at

the center frequency. The response should start

to take on the desired shape and symmetry.

Setup the analyzer for 1 dB/div (2 dB/div for a

tracking generator) on the transmission channel

and then re-adjust the rods in the same fashion.

Make sure that the return loss curve meets or

exceeds the published specification over the

range and is relatively symmetrical. Fine adjust

the tuning rods to adjust symmetry.

7) Lock all tuning rods after the desired response

is obtained. Note that a slight dissymmetry in

either the transmission or reflection response

may be unavoidable.
