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 6138 family of channelized signal boosters is designed to operate in either the 700 or 800 MHz range. Dual band models are available that include both 700 and 800 MHz systems in the same enclosure box.

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 stability depends only on the stability of the signal source producing the signal to be boosted.

Using high quality connectors with gold center pins is advised. Flexible jumper cables made of high quality coax are also acceptable for connecting to rigid cable sections.
REQUIRED EQUIPMENT The following equipment is required in order to perform 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 analyzer 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.
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.

Channel Module The uplink input signals and the downlink input signals are applied to a down-converter board when they enter the channel module. Within the channel module input signals are down converted, digitized, and DSP filtering is performed. There are two styles of Channel modules available, a 14 channel version and a 30 channel version.
up converter boards are used. Signal booster models that have the fiber-optic option installed in them have enhanced down-converter boards that are capable of dealing with the low level signals from the optical conversion. Uplink and Downlink Output Signals Uplink and Downlink output signals leave the channel module at the UL OUT and DL OUT connectors respectively. The 700 and 800 MHz uplink output signals are combined with a directional coupler then passed on to a power amplifier stage.

channel module as well as updating any displayed data from the module, but only after the button is pressed. FILTER AREA This is a user interactive area where the field engineer can program the operating characteristics of the selected channel filter. 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 as applicable.
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 in the interface boxes to the channel module as well as updating any displayed data from the module, but only after the button is pressed.
APPENDIX A Front Panel Ethernet Connectivity ETHERNET CONNECTIVITY The front panel User Interface connector on the booster provides for 10/100 BASE-T Ethernet connection 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.

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.
APPENDIX B Changing Your Service Computers IP Address When you initially direct connect your laptop service computer to the booster it will be necessary to change the computers IP address. The procedure for doing this varies depending upon your operating system. As an example, this appendix illustrates how to make the change using the Microsoft XP operating system. The procedure for other operating systems will vary slightly from this example. Consult with your IT support personnel if needed.
