    Since the satellite orbits are located between latitudes 55 North and 55 South, this allows for the best possible reception. Meinberg provides their own GPS receivers which operate with an antenna/converter unit and thus allow for very long antenna cables, but some devices also include GNSS receivers which support other satellite sys- tems like GLONASS, or Galileo in addition to GPS.

    5 Master oscillator 5 Master oscillator By default the GNS181PEX is equipped with a TCXO (Temperature Compensated Xtal Oscillator) as master oscillator to provide a good time accuracy and frequency stability. As long as an input signal is supplied the frequency of the oscillator is adjusted from the input signal, and if the input signal is disconnected afterwards the card can still provide accurate time for a certain holdover interval.

  • Page 18: Gns181Pex Features

    6 GNS181PEX Features The board GNS181PEX is designed as a „low profile“ board for computers with PCI Express interface. The rear slot cover integrates the antenna connector, a BNC connector for modulated time codes, two status LEDs and a 9pin SUB-D male connector. The card can be equipped with the delivered low profile cover. The I/O signals, available over a D-Sub plugs (RS-232 - PPS, PPM), are not available in this case.

  • Page 19: Time Capture Inputs

    6 GNS181PEX Features 6.3 Time capture inputs The board provides two time capture inputs called User Capture 0 and 1 (CAP0 and CAP1) which can be mapped to pins at the 9 pin connector at the rear panel. These inputs can be used to measure asynchronous time events.

  • Page 20: Pulse And Frequency Outputs

    6.4 Pulse and frequency outputs The pulse generator of the clock GNS181PEX contains three independent channels (PPO0, PPO1, PPO2). These TTL outputs can be mapped to pins at the 9-pin connector at the rear slot cover by using a DIP switch.

    6 GNS181PEX Features 6.5 DCF77 Emulation The clock generates TTL level time marks (active HIGH) which are compatible with the time marks spread by the German long wave transmitter DCF77. This long wave transmitter installed in Mainflingen near Frank- furt/Germany transmits the reference time of the Federal Republic of Germany: time of day, date of month and day of week in BCD coded second pulses.
