PPS Source-NR3700-PPS

Source for PPS


The NR3700-PPS is a low cost means to have a source of PPS when GNSS is not available. The PPS is synthesized from a high stability OCXO offering +-50 ppb/year. The synchronous counter keeps pulse to pulse jitter well below a ns. The pulse frequency and pulse width are factory programmable.

  • PPS pulse width factory programmable in 1 usec steps
  • While a PPS source the frequency is also factory programmable.
  • Operates from DC Power in three ranges +- (10 to 18, 18 to 36, 36 to 65) VDC or an AC Adapter
  • Temperature stability 10ppb/range
  • Aging +-5 ppb/day, +-50 ppb/year
  • Drives 50 Ohm loads 5 or 3.3 Vdc CMOS levels
  • LVDS output
  • Optional 10 MHz sine

    Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
