in a public address system, a signal booster can start to self oscillate. This can occur when the isolation between the Uplink and Downlink antennas does not exceed the signal boosters gain by at least 15 dB. Oscillation will reduce the effectiveness of the system and may possibly damage amplifier stages. Isolation values are relatively easy to measure with a spectrum analyzer and signal generator. REQUIRED EQUIPMENT The following equipment is required in order to perform the antenna isolation measurements.
may have to be narrowed and it’s input attenuation 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.
Uplink and Downlink Input Signals Uplink input signals are picked up by the DAS antenna and are passed through an isolator before being applied to a bandpass filter. The signals pass through the filter and are fed into the uplink input port of the channel module. Downlink input signals are picked up by the Donor antenna and are passed through an isolator before being applied to a bandpass filter.
sion and a 30 filter version. After DSP filtering the analog signal is recreated and up converted with an up-converter board to the original frequency before being output from the channel module at the downlink and uplink output ports. Up converter boards are available in two different styles including low level and high level. If the signal booster is a high-power model then a low level up converter board is used in the channel module.
Uplink and Downlink Output Signals Uplink output signals leave the channel module at the UL OUT port. The signals are then passed on to a power amplifier stage. The output of the power amplifier is passed through a filter then radiated from the donor antenna. Note: When the booster is operated at the maximum uplink output power level (+37 dBm) the gain of the donor antenna should be limited to 0 dBi. Downlink output signals leave the channel module at the DL OUT port.
When the unit is powered ON there are LED’s located on several of the subassemblies within the cabinet that will become illuminated to indicate the ON condition. The function of each of these indicator LED’s are listed in Table 3. Alarm Form-C Contacts The ALARM Form-C relay contacts are located on the back panel of the unit as shown in Figure 7. These screw terminals are intended for connection to the customer’s supervisory and data acquisition system.
the alarm status. This is accomplished by using EOL (end-of-line) resistors at the alarm terminal strip in the signal booster cabinet. The value of the EOL resistors is a function of the alarm panel so you should consult the manual for the alarm panel when you are determining the resistor value.
tains a group of related user functions. Each tab of the Control Panel presents a new screen. Selection is made by placing your cursor over the tab and performing a left click. FILTERS TAB The Filters page gives an overview of all the filters associated with each branch in the booster system. Refer to Figure 10. The link drop-down box allows you to select which branch you want to overview. Press the down arrow button and highlight the desired branch. Each filter is accorded one row in the display.
you have interactive access to the Filter Detail page you can begin programming the individual filters that you want the booster to pass in the uplink and downlink directions. The Filter Detail page is designed to interact with one filter at a time. To program individual filters you must select the branch and the filter of interest using the Link and Filter boxes on the left side of the screen.

overflow, the status indicator will turn red during a fault condition. NOTE When the Summed Alarm indicator is red, if the cursor is placed over the indicator, a message tab will appear briefly describing the reason for the alarm condition. Seven additional parameters are displayed with numerical values.
Figure 17: The System page. Oscillation Detection This feature shuts off the output signals from the booster for both the uplink and downlink whenever an oscillation condition is detected. Oscillation detection occurs whenever port to port isolation falls down to 25 dB or less. For normal operation the port to port isolation needs to be at least 10 dB greater than the gain of the booster.
Figure 19: The Network Configuration display. Network Configuration Submenu Values for IP Address, Netmask, the Gateway and MAC Address are displayed on the network configuration page. Refer to Figure 19. The network configuration page allows the user to enable or disable DCHP. The Dynamic Host Control Protocol (DHCP) is a standardized networking protocol used on IP networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services.
User Administration Submenu The User Administration submenu allows the user to enable password protection for the web-based interface program. The boxes on this page are interactive. To make changes click inside the box and a cursor will appear. Refer to Figure 20. The user is queried for a User Name and Password. The default user name is “admin” and the default password is “admin”. Once the correct user name and password are entered then a menu box for creating a new user will be presented.
2) Use the Network Configuration to setup the DHCP as either active or inactive. When DHCP is inactive the deck will be using a static IP and the user must enter values for IP address, netmask, and gateway. Make sure you consult with your IT department regarding setting DCHP active or inactive. 3) Use the SNMP Configuration to enter up to three destination device addresses. These are addresses where the SNMP feature will send traps whenever a qualifying event takes place.
MAINTENANCE AND REPAIR Signals boosters manufactured by Bird Technologies can perform for years with little maintenance and repair. However, if the amplifiers are subjected to excessively high signal levels, power surges or lightning strikes, failures may occur. The following procedures may be followed for detecting a malfunctioning subassembly or as part of a periodic maintenance program. 1) Heatsink areas should be clear of dust and debris.
Channel Module Replacement The SBIII channel module is field replaceable. Follow the steps listed below in sequential order. The required tools are a 5/32” hex head driver. 6) Remove the 12 hold down screws (5/32” hex head) that hold the channel module assembly to the cabinet. The screw heads are accessible from the heatsink side of the assembly. Refer to Figure 25. 1) Turn off power to the signal booster. 2) Disconnect the 6 VDC power cable.
2) Disconnect the 6 VDC power connector on the lower left side of the module. 2) Disconnect the AC plug on the right side of the supply. 3) Disconnect the control cable (one for each channel module). The control cable is located at the lower left side of the control module and has a white plastic pull tab on it. 3) Disconnect the three (6 Volt) DC Output plugs on the left side of the supply. 4) Disconnect (3) Form-C control lines from the top of the module.
