1 FCC NOTICE NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
BDA1300 2 Equipment Manual INTRODUCTION TO BDA’s Bi-Directional Amplifiers (BDA’s) are radio frequency amplifiers that amplify signals in two directions. There are two basic BDA Applications; Line Amplifiers and “Off-the-Air”... 2.1 BDA Line Amplifier System Application In-building RF distribution system usually takes on one of several forms including, but limited to, radiating cable, distributed tapped radiators, or high power repeater antennas.
BDA1300 2.3 Equipment Manual BDA “Off-the-Air” Amplifier System Application The Bi-Directional Amplifier is intended to extend Cellular coverage into areas with coverage deficiency such as inside office buildings, shopping malls, hospitals etc. It is designed to be located independent of the donor site and must be equipped with its own antenna systems - one to communicate with the donor site and the other(s) to communicate with portables in the shadow zone.
BDA1300 Equipment Manual 3 BDA1300 Bi-Directional Amplifier Description 3.1 BDA1300 Functional Description The BDA1300 series Amplifier is a compact, yet flexible bi-directional amplifier. It is equipped with a microprocessor based controller to provide a friendly user interface and to simplify set up and operating procedures. The BDA1300 consists of the following functions: • 1 BDA Controller: Microprocessor based units that provides all control, fault monitoring and settings for the BDA.

BDA1300 4.3 Equipment Manual Power De-Rating Requirements BDA’s will amplify all signals that fall within their Pass-Band range. The output power will be “shared” between all channels being amplified. Another multiple channel effect is Intermodulation signals produced from non-linear effects between the intended channel signals. These intermodulation may cause interference to receiving equipment. In order to minimize Intermodulation signals, Power de-rating must be applied.

BDA1300 5.6 Equipment Manual Connecting the Power Cables AC Power and RF Connections should be installed with all standard installation practices for lightning protection. This includes the grounding and electrical bonding together of all equipment racks and cabinets in the room. It also includes a grounding of the primary antenna cable and the installation of proper surge suppression (lightning arrestor) equipment at the entrance to the equipment room.
BDA1300 Equipment Manual 6 Antenna Installation ! ! ! ! All Antenna Installation is to be performed by Qualified Technical Personnel only. Antenna Installation Instructions and locations below, are for the purpose of satisfying FCC RF Exposure Compliance requirements. The Roof Top Antenna for linking to the Donor Site is a directional (high gain) Antenna fixedmounted physically on the side or top of a building, or on a tower. The Antenna Gain must be no more than 10 dB.
BDA1300 Equipment Manual 7 BDA Controller and Configuration Kaval’s BDA’s can be configured very easily without the use of any tool via the BDA Controller. The BDA must be powered up before setting the BDA operating parameters. The operating parameters are set to specific defaults at the Kaval factory. All controller settings are recorded in the BDA Controller Settings As-built list. The customer may also reset these parameters to optimize BDA performance in the operating condition. 7.
BDA1300 7.3 Equipment Manual BDA Controller User Interface LED and Audible Indicators: LED and audible indicators are used to enhance the user interface of the BDA. 10 LEDs and buzzer are described below: PWR FAIL Lights if primary power fails, and the system is on Battery Backup. BATT Lights when the battery (if installed) voltage drops below 24 VDC which roughly indicates 50% of backup capacity remaining.
BDA1300 Equipment Manual Functions: BDA system parameters can be set using the four button BDA controller keypad. Description for the keypad buttons are listed below: 7.4 ON/OFF Power Switch for turning the BDA operation on and off. Note that this only controls the BDA Controller, Amplifiers, PA’s, and Fans; the DC Power Supply is still operating where BDA controller is switched off.
BDA1300 Equipment Manual CAUTION: The operator should not reset any other parameters. To set these parameters please follow the programming guide for each parameter. The programming guide shows the menus and key entries required to modify each parameter. The programming guides for each parameter and an example are included at the end of this section. Please note that it is recommended that any field-modified parameters be recorded on the “BDA CONTROLLER SETTINGS - As-Built” sheet provided with the BDA.
BDA1300 7.7 Equipment Manual BDA Controller Configuration Guide NOTE: Refer to the CONFIGURATION GUIDE diagrams at the end of this section to navigate throughout all menus. There are four levels of displays in the BDA controller: • • • Level 1 - Status menus Level 2 - Main menus Level 3,4 - Submenus Status Menus When the BDA is first turned on, the controller performs a self-diagnostic check.
BDA1300 Equipment Manual Backup Power voltage is displayed in volts to a resolution of 10 mV. If Backup Power is not installed, display says “None”.
