    TimeVault requires a 12 V antenna and may severely damage any antenna that does not support 12 V. For non-standard antenna types, contact Symmetricom for assistance. Optionally, you can add an RS-232 serial interface for local control using a terminal emulation program.

  • Page 27: Antenna Information

    Site Preparation 2.1.3 Antenna Information Voltage Requirement and Signal Levels TimeVault requires a 12 V antenna. Any antenna that does not support 12 V may be severely damaged if plugged into TimeVault. The GPS Synchronized Receiver, integral to TimeVault, operates on the L1 (1575.42 MHz) signal and the C/A code (1.023 MHz bit rate) with a minimum signal level of –162.0 dBW and a maximum signal level of –137.0 dBW.

  • Page 28: Gps Window-Mounted Antenna (140-619) Installation

    Window mounted antennas have a restricted view of the sky, yielding intermittent satellite coverage. With single satellite timing, a network time server can synchronize with individual GPS satellites as they pass through the antenna’s field of view. Placing the Window Antenna Select the window with the best unobstructed view of the sky.

  • Page 32 Chapter 2: Installation and Start-Up Satellite Acquisition Satellite acquisition begins at power-up and continues until power-down. The length of satellite acquisition time depends on many factors, some of which are described below. When TimeVault performs initial acquisition of GPS satellite data, it ‘listens’ for all available GPS signals.
