OVERVIEW

Signal boosters extend radio coverage into areas

where abrupt propagation losses prevent reliable

communication. The system receives an RF signal,

raises its power level, and couples it to an antenna

so that it can be re-radiated. The TXRX model 611-

70A channelized signal booster is designed to

operate in the 450 to 512 MHz range. The system

is based on a module design with each module

capable of handling one uplink and one downlink

channel simultaneously. The size of the system

can be tailored to the customers needs by increas-

ing or decreasing the number of modules used.

Each module is bi-directional with one downlink

and one uplink signal branch. Each of the two

branches in a module are independently tunable to

their required pass frequency via software inter-

face. Specifications for the 611-70A family of chan-

nelized signal boosters are listed in Table1.

Down / Up Conversion

A channelized signal booster has much in common

with a superheterodyne (superhet) receiver. The

incoming signal is converted to a lower frequency

so that single channel selectivity can be obtained.

It is then filtered. Unlike the superhet receiver how-

ever, the signal is not demodulated. Instead, it is

up-converted back to its original frequency where it

is further amplified to reach a useful power level.

Figure 1 shows a simplified block diagram that

illustrates the down/up conversion principle. An

incoming signal at (Freq IN) is amplified and

applied to the first mixer along with a signal from a

local oscillator (Freq LO). A third signal at an inter-

mediate frequency (Freq IF) is produced as a result

of the mixing. The intermediate frequency is given

by the following relationship:

(1) Freq IF = Freq IN - Freq LO

The IF signal from the mixer then passes through

digital filtering with single channel bandwidth

before being amplified and passed on to the sec-

ond mixer. The second mixer also receives the

same local oscillator signal (Freq LO). The result is

a mixing product frequency at the output of mixer

2. The output frequency (Freq OUT) is given by the

following relationship:

(2) Freq OUT = Freq IF + Freq LO

Substituting equation (1) for the “Freq IF” term in

equation (2) allows the “Freq LO” terms to be can-

celed yielding:

(3) Freq Out = Freq IN

The implication of equation (3) is that the frequency

stability of the signal that is processed by this type

of signal booster is not affected by the frequency

stability of the signal booster itself. Frequency sta-

bility depends only on the stability of the signal

source producing the signal to be boosted. A shift

in the LO frequency will cause the center of the fil-

ter bandwidth to move with respect to the signal.

For very narrow filter widths, the channel modules

LO may be locked to a high stability 10 MHz refer-

ence.

UNPACKING

It is important to report any visible damage to the

carrier immediately. It is the customers responsibil-

ity to file damage claims with the carrier within a

short period of time (1 to 5 days). Care should be

taken when removing the unit from the packing box

to avoid damage to the unit.

INSTALLATION

The following sub-sections of the manual discuss

general considerations for installing the booster. All

work should be performed by qualified personnel

and 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 this unit. However, safety and serviceability

are also key considerations. The unit should be

located where it can not 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 it should become

detached from its mounting for any reason.

The booster needs to be installed such that there

can be unobstructed air flow around the equip-

ment. Insure that the ventilation fans at the rear of

the module cabinet are unobstructed. The various

subassemblies within the module cabinet will stay

warm during normal operation so in the interest of

equipment longevity, avoid installation locations

that carry hot exhaust air or are continually hot.

Installing the Booster

The channelized booster system is shipped to the

customer in sections which must be assembled

into the rack before use. The sections which must

be installed in the rack for a standard system

include the module cabinet and filters. High-power

systems may also require the installation of a

hybrid combiner assembly. To install the channel-

ized booster into the rack perform the following

steps.

1) Install the filter assemblies at the bottom of the

rack using the supplied mounting screws. Face

the cable connectors towards the back of the

rack.

2) Install the module cabinet in the rack with the

supplied screws. Place the module cabinet

above the filters. Leave enough room above the

module cabinet to install a second cabinet if

required.

3) For high powered systems install the hybrid

combiner assembly in the rack using the sup-

plied mounting screws. For convenience its

best to place the combiner in the middle of the

rack between the filters and the module cabinet.

4) Interconnect the sections with the supplied

cables. The cable ends are tagged at the fac-

tory before shipment to help you make the cor-

rect interconnections.

TX RX Systems Inc. Manual 7-9469-1.7 02/08/10 Page 3

Connections

All RF cabling connections to the booster should

be made and checked for correctness prior to pow-

ering up the system. Connectors are available from

the filter assemblies for connection to the signal

distribution system. Make sure 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.

The booster is designed to be plugged into a single

phase AC line (90 - 250 VAC at 50/60 Hz) or a + 28

Volt DC source. A connector will be available at the

back panel of the module cabinet for connecting

either the AC or DC source voltage. At the time of

manufacture the equipment will be configured for

either AC or DC operation as per the customers

request and only one of the connectors, AC or DC,

will be available on the back panel. Additionally,

the AC connector has a 5 Amp fuse for protection.

Antenna Isolation

Antenna isolation between uplink and downlink

should be measured before connecting the signal

booster to the antenna system. This step is neces-

sary 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.

Just like the feedback squeal that can occur when

the microphone and speaker get too close together

in a public address system, a signal booster can

start to self oscillate. This can occur when the iso-

lation between the Uplink and Downlink antennas

does not exceed the signal boosters gain by at

least 15 dB. Oscillation will reduce the effective-

ness of the system and may possibly damage

amplifier stages. Isolation values are relatively

easy to measure with a spectrum analyzer and sig-

nal generator.

REQUIRED EQUIPMENT

The following equipment is required in order to per-

form the antenna isolation measurements.

1) Signal generator for the frequencies of interest

capable of a 0 dBm output level. Modulation is

not necessary.

2) Bird Technologies “Signal Hawk” spectrum ana-

lyzer which will cover 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.

MEASUREMENT PROCEDURE

To measure the antenna isolation perform the fol-

lowing in a step-by-step fashion.

1) Set the signal generator for a 0 dBm output level

at the center frequency of the boosters pass-

band.

2) Set the spectrum analyzer for the same center

frequency and a sweep width equal to or just

slightly greater than the passband chosen ear-

lier in step 1.

3) Temporarily connect the test leads of the signal

generator and spectrum analyzer together

using a female barrel connector, see Figure 2.

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 2, connect the generator

test lead to one side of the antenna system and

the spectrum analyzer to the other then observe

the signal level. The difference between the

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 it’s input attenua-

tion reduced. The isolation value measured

should exceed the signal booster’s gain figure

by at least 15 dB.

5) Repeat step 4 again with the signal generator

set at the passband edges in order to see if the

isolation is remaining relatively constant over

the complete width of the passband.

6) Repeat the isolation measurements if necessary

at other system passbands to determine the

overall minimum isolation value for the system.

Physical modification of the antenna system

maybe required in order to reach an acceptable

minimum value.

TX RX Systems Inc. Manual 7-9469-1.7 02/08/10 Page 4

RF EXPOSURE

To comply with FCC RF exposure compliance

requirements, a separation distance of at least 100

cm must be maintained between the antenna of

this device and all persons. This device must not

be co-located or operating in conjunction with any

other antenna or transmitter.

FUNCTIONAL BLOCK DIAGRAM

Figure 3 is the functional block diagram of the

standard channelized signal booster model 611-

70A. Figure 4A and 4B show the front and rear

views of the booster cabinet.

Downlink / Uplink Input Signals

Downlink and Uplink input signals are applied to a

distribution amplifier. This is an ultra-low noise high

linearity amplifier with a gain of 18.9 dB. Following

the distribution amp is a 6-way power divider which

is used to distribute the signal to individual channel

modules within the booster cabinet. Downlink sig-

nals are applied to the down converter board of a

downlink branch while uplink signals are applied to

the down converter board of an uplink branch.

Downlink / Uplink Output Signals

Downlink output signals leave the channel module

at the DL OUT connector and are applied to an

active combiner. The active combiner amplifies

and combines signals from multiple modules. Sig-

nals output from the active combiner are applied to

the filter assemblies. Uplink output signals leave

the channel module at the UL OUT connector and

are also applied to an active combiner. The active

combiner amplifies and combines signals from

multiple modules. Following the active combiner

are the filter assemblies.

The exact filter assemblies used in your channel-

ized booster system will depend upon the overall

communications system design and your particular

RF environment. A system level drawing will be

supplied with your booster which details the filter

assemblies used and their interconnections.

Channel Module

The channel modules are bi-directional with each

module containing one downlink branch and one

uplink branch. The branches are functionally identi-

cal because the same set of circuit boards are

used in each branch. The uplink and downlink

branches may be programmed to any frequency in

the appropriate band, 450-470, 470-491, or 491-

512 MHz. It is not recommended to program an

uplink and downlink to the same frequency or feed-

back may occur. Within the channel module, input

signals are down converted, digitized, and DSP fil-

tering is performed. Then the analog signal is rec-

reated and up converted to the original frequency.

OPERATION

Power is applied to the channelized booster by

plugging in the AC or DC power cord (depending

on how the system was configured for input

power). There is a Power-ON LED located on the

front of the unit (near the user interface connector)

which will illuminate when power is applied to the

cabinet. The ventilation fans at the rear of the cabi-

net will be continuously on when power is applied.

Module LED’s

There are six LED indicators on the front of each

channel module, 3 for the uplink branch and 3 for

the downlink branch. The function of each of these

indicator LED’s are listed in Table 2.

Module Configuration

The channelized signal booster provides front

panel Ethernet connectivity that allows access to a

web-based interface for programming the individ-

ual modules. Programming will require connecting

your laptop computer to the User Interface connec-

tor on the front of the booster cabinet. Figure 4A

shows the interface connector (LAN). A standard

Ethernet crossover cable is used to make the con-

nection between your laptop and the booster cabi-

net. Refer to Appendix A at the back of this

manual for detailed instructions on how to properly

connect your computer to the LAN port of the

booster.

Once your laptop is properly connected to the sig-

nal booster, if password protection is enabled, the

password request box will appear in your web

browser as shown in Figure 5. Type in your pass-

word and press the OK button. The password box

will disappear and the web-based interface screen

will appear as shown in Figure 6.

Once your password has been

entered and validated a 15 minute

inactivity timer is started. If the user

does not make any changes to the

web page interface the system will re-

arm security once the inactivity timer

expires. The user will then need to re-

enter the password.

COMMAND BUTTONS

Clicking on a command button (located on the

extreme left hand side of the screen) performs the

associated task immediately. The submit and

reload buttons in the bottom left corner allow any

changes you make to the display/interface boxes

to be downloaded to the booster. The submit and

reload buttons act like a trigger sending any

changes you made on the web-page interface

screen to the selected booster module, but only

after the button is pressed.

MESSAGE BARS

There are two message bars at the bottom of the

web-page screen. The rightmost message bar dis-

plays connection status messages and the leftmost

message bar displays system status messages.

The connection status messages reveal the rela-

tionship between the LAN interface and the control

board within the booster cabinet. Without a prop-

erly functioning connection you will not be able to

interface with the control board or individual mod-

ules. All of the possible connection status mes-

sages are listed in Table 3 along with a brief

description of what each message means. The

system status messages vary depending on what

aspect of the booster system you are interacting

with. All of the possible system status messages

are listed in Table 4.

DISPLAY/INTERFACE AREAS

The display/interface area of the web-based inter-

face is divided into five functional areas including;

Settings - this is a user interactive area where the

field engineer can program the operating charac-

teristics of the selected module. Each parameter in

the settings area can be changed by clicking in the

box and typing in the new values or by pointing at

an arrow to display a drop down box. Most of the

adjustable parameters have adjustment limitations

which can be displayed in a message box by click-

ing on the question mark symbol next to the

parameter. The parameters are self-explanatory.

Remember the changes you make are only appli-

cable to the selected channel module. After you

have made changes to the various parameters

press the “submit” command interface button

(lower left corner of the screen) in order to copy the

changes into the module itself.

Filters - this area allows you to modify the charac-

teristics of the digital filtering used by the channel

module. Parameters that can be changed include

the occupied bandwidth, adjacent channel offset,

passband ripple, adjacent channel rejection, and

delay.

When the “Design Filter” button is pressed a cus-

tom design template will be displayed as shown in

Figure 8. Remember the changes you make are

only applicable to the selected channel module.

After you have made changes to the various

parameters press the “submit” command interface

button (lower left corner of the screen) in order to

copy the changes into the module itself.

Information - this area is non-interactive and is

used to display basic information about the

selected channel module.

Data - this area is also non-interactive and displays

detailed technical parameters. The polling function

can be changed between either enabled or dis-

abled. Click on the bubble next to the function to

change the polling status. In the example shown in

figure 6 the polling is currently disabled. To enable

polling you would point at the bubble next to the

enable label and right click.

Status - this area is used to give a quick overview

of eight channel module parameters. Each param-

eter can be in one of three states; alert, active or

inactive. Each state is color coded as shown in fig-

ure 6.

ADDITIONAL INTERACTIVE PAGES

In addition to interfacing with the individual channel

modules the web-based interface also provides

access to two additional areas of interaction includ-

ing Admin and System. Access to these additional

areas is through the tabs at the very top of the dis-

play/interactive area. When a tab is clicked the

page associated with that tab will be displayed and

you can interact with the functions.

Admin - the admin page allows the user to change

the boosters network settings and enable pass-

word protection for the web-based interface pro-

gram. The boxes on this page are interactive. To

make changes click inside the box and a cursor will

appear.

System - the system page lists the applet and con-

trol board software versions. A customer desig-

nated location name can be recorded and the

number of modules installed in the system is dis-

played. There is also a system logbook available

on this page.

ETHERNET CONNECTIVITY

The front panel User Interface connector on the

booster provides for 10/100 BASE-T Ethernet con-

nection using the TCP-IP protocol. This product

feature allows access to a web-based interface for

programming the individual modules within the

booster. The web based interface requires a JAVA

runtime environment (version 1.6.0 or later) to be

installed on your laptop. The JAVA software can be

downloaded free of charge from the Sun Microsys-

tems website found at “http://java.com/en/down-

load/index.jsp”. The channelized booster is

shipped from the factory with a default IP address

of “192.168.1.1”.

Two connection schemes are discussed including

a direct connection from your laptop computer to

the booster front panel as well as connecting the

booster to a networked environment. A direct con-

nection (at the installation site) should be estab-

lished the first time you interface to the booster

using the fixed IP mentioned above. Once the ini-

tial communications are established the IP address

in the booster can be changed to permit a net-

worked connection (from a remote site such as

your office).

Direct Connection

Your initial connection to the booster system

should be a direct connection to the front panel

using an Ethernet crossover cable. Figure A1

shows the proper way to interconnect the equip-

ment as well as the pinout for a CAT-5 crossover

cable.

REQUIRED EQUIPMENT

Cat-5 Crossover Cable

Laptop Computer with a network interface card

installed. In addition, the JAVA run-time environ-

ment version 1.6.0 or later, and a web browser

such as Internet Explorer must also be installed on

the laptop.

PROCEDURE

To connect your laptop computer to the front panel

LAN port and access the web page interface, per-

form the following steps;

1) Insure the JAVA runtime environment software

is installed on your laptop.

2) Connect your laptop network port to the LAN

connector on the booster front panel using a

standard CAT-5 Crossover cable.

The front panel LAN connector

has two built-in bi-color status

LED’s which will aid you in estab-

lishing communications. The

meaning of each LED is shown in

Table A1.

3) The left-most (LINK) status LED built-in to the

LAN port connector should illuminate amber or

green indicating that a good physical connec-

tion is established between your computer and

the booster.

4) Insure that your laptop’s IP address is compati-

ble with the default address of the signal

booster system. This may require changes be

made to the Ethernet adaptor address on your

laptop (refer to Appendix B). Your laptop’s IP

address will need to be set to “192.168.1.2”

along with a subnet mask of “255.255.255.0”.

The right-most (ACTIVITY) status LED built-in

to the LAN port connector will turn amber or

green indicating good TCP-IP communications

are established between the laptop and the

booster.

5) Launch your web browser software on the lap-

top.

6) In your web browsers address box type-in the

address of the booster “http://192.168.1.1” and

press the ENTER key. The web page interface

to the booster should appear in your laptop’s

browser window. When you launch the web

page you may notice that the JAVA applet will

load first.

Networked Connection

Before attempting a networked connection to the

signal booster system consult with your IT support

personnel for information concerning the correct IP

address to use and any additional connectivity

issues such as firewalls. Once you have the correct

IP address you will need to direct connect to the

booster system as discussed in the earlier section

of this appendix and reconfigure the booster LAN

port with this new address. You can then connect

the signal booster system using a straight-through

CAT-5 cable to the networked environment and

interface to it from a remote computer. Figure A2

shows the proper way to interconnect the equip-

ment for a networked connection as well as the

pinout for a straight-thru CAT-5 cable.

ment version 1.6.0 or later, and a web browser

such as Internet Explorer must also be installed on

the laptop.

PROCEDURE

Before a networked connection can be established,

the booster LAN Port must be changed to an IP

address that’s compatible with your network. If you

are unsure how to determine this address check

with your IT support personnel. To connect the

booster LAN port to a networked environment and

access the web page interface, perform the follow-

ing steps;

1) Change the boosters LAN port IP address. To

do this, direct connect your laptop to the

booster as discussed in the earlier section of

this appendix titled “Direct Connection” and fol-

low steps 1 through 4.

2) Launch the configuration Applet in your web

browser.

3) Click the “Admin” tab at the top of the interface

display screen.

4) To be safe, take note of the settings currently

displayed.

5) Select the “User Static IP” radio button.

6) Enter the following settings provided by your

network administrator;

A) IP Address

B) Subnet Mask

C) Gateway Address

7) Click the “Submit” button to apply the changes.

8) Once the changes have been successfully

applied close your web browser.

9) Launch the configuration Applet in your web

browser using the newly entered IP address.

TX RX Systems Inc. Manual 7-9469-1.7 02/08/10 Page 17

When you initially direct connect your laptop ser-

vice computer to the booster it will be necessary to

change the computers IP address. The procedure

for doing this varies depending upon your operat-

ing system. As an example, this appendix illus-

trates how to make the change using the Microsoft

XP operating system. The procedure for other

operating systems will vary slightly from this exam-

ple. Consult with your IT support personnel if

needed. To change the IP address (assuming the

Microsoft XP operating system is being used) per-

form the following in a step-by-step fashion;

1) Select “Start” from the status menu.

2) Single click the “Control Panel” choice from the

“Start” pop-up menu as shown in Figure B1.

3) From the “Control Panel” icon selections double

click on the “Network Connections” icon. Refer

to Figure B2.

4) When the “Network Connections” folder opens

double click on the “Local Area Connection”

icon. See Figure B3.

5) The “Local Area Connection Status” box will

open. Single click the “Properties” tab as shown

in Figure B4. Note: If you do not have the cable

connected between the service computer and

the booster front panel the “Local Area Connec-

tion Status” box will not open. Instead proceed

to step 6.

6) The “Local Area Connection Properties” box will

open. Use the arrow buttons to scroll down the

list until the “Internet Protocol (TCP/IP)” choice

is highlighted as shown in Figure B5. Click the

“Properties” tab at the right-center of the box.

7) Select the “Use the following IP address” bub-

ble. Make sure the circle is filled-in. Refer to

Figure B6.

8) Enter the new IP address and subnet mask val-

ues as shown in Figure B7. To interface your

computer to the signal booster use an IP

address of “192.168.1.2” and a subnet mask of

“ 255.255.255.0”.

9) Click on the “OK” tab to initiate the changes.

This completes the procedure. Close any open

boxes.
