GPS Frequency Standard NFG-8USV

Key features

  • Eight decoupled sinus outputs
  • Outputs independently configurable to 10 MHz, 5 MHz, or 1 MHz resp.
  • Battery backup to bridge power blackouts
  • 1 PPS input (TTL)
  • 1 PPS output (TTL)
  • Alarm outputs for remote monitoring

Uses

  • Synchronisation of test equipment in the laboratory
  • Frequency standard for single frequency networks (e.g. for DVB-T, DAB, DMB)
  • Substitute for Rubidium frequency standards

Description

The frequency standard NFG-8USV provides eight phase-coupled sinus-shaped output signals and one 1 PPS signal. They are produced by a common oscillator that is synchronised by a 1 PPS signal that will be provided by an internal GPS receiver or by an external clock resp. The circuit combines the long-term stability of GPS withthe short-term stability of the used OCXO even for the case of temporal loss of GPS reception.

The GPS antenna input is equipped with an internal switchable bias to feed active antennas. A second input allows for the alternative synchronisation by an external 1 PPS signal that has priority over the internal source. Eight BNC outputs provide decoupled sinus signals that can be configured to 10 MHz, 5 MHz, or 1 MHz resp. A15-pole SUB-D socket carries five relay contacts for the remote monitoring of the main functions. The integrated UPS warrants the long-term stability for at least one hour.
