    1.1 Electric Shock Hazard To avoid electric shock, switch the BDA “OFF” prior to performing any repairs. All repairs beyond modular replacement must be performed by Andrew Trained Technicians. 1.2 Hot Surface Hazard RF power into the BDA will be limited by the use of high power attenuators. These attenuators will be located at the transmitter source.

  • Page 61: Installation

    INTENTIONALLY LEFT BLANK INSTALLATION 6.1 BDA Installation & Gain Setup INSTALLATION 1 Install the BDA in a standard 19” rack. The BDA should be placed in a location where the interconnect cables (i.e. fiber, RF and serial cable) can be easily installed and not susceptible to damage.
  • Page 62 2 Plug the BDA into a 120 VAC single phase three wire grounded receptacle (5-15R). 3 Connect the RF antenna cable to the antenna port (Type-N Female) on the rear panel of the BDA. If a RF fed BDA was installed, connect the base station RF cable to the base station port (Type-N Female) on the rear panel of the BDA.
  • Page 63 The RF fed BDA gain setting is performed at the factory and no field adjustments are required. With a 48 dB factory gain setting, the maximum input signal level is –18 dBm. This input level will ensure that FCC power limit (+30 dBm) is not exceeded. UPLINK GAIN SETUP The fiber fed BDA provides 18 dB of gain for 9 dB of optical loss.

  • Page 64: Bda Maintenance / Troubleshooting & Module Care

    The RF fed BDA uplink gain setting was performed at the factory and no field adjustments are required. For a 48 dB gain setting, the maximum input signal level is – 14 dBm with ALC active and – 43 dBm without ALC active. Note, the ALC is activated at the factory and when the input level exceeds –...

  • Page 66: Alarm Module Removal (Optional Equipment)

    Any active module not installed in a BDA must be kept in an anti-static bag or container. Any module sent back to Andrew Corporation for investigation/repair must be shipped in a anti-static container. Please contact Andrew Corporation quality department before returning a module.
  • Page 67 When tightening RF Type-N connectors located on the rear of the BDA, use a dedicated N- Type torque wrench. If Type-N connectors are over-tightened, irreparable damage will occur. Do not use adjustable pliers to loosen or tighten connectors. When connecting or disconnecting the fiber optic cable connectors located on the front panel of the fiber optic transceiver module, exercise caution not to touch the optical connector center pin.
