Frequency References

Frequency References

Novus offers a diverse set of frequency reference products. From our low cost TCXO frequency references to our Rubidium frequency references to our high-performance GPS disciplined references (GPS DO) -Novus frequency references offer low phase noise, accuracy and reliability. From one to twenty channels, modular, rackmount, portable or micro-packaged- Novus offers a form factor to meet your frequency reference needs. Available features include redundant power, SNMP, self-test, ultra-low phase noise, dual-Time base, real-time Allan Deviation, and synthesized frequency references.

For use cases that demand greater precision, we have GPS disciplined oscillators that will provide single satellite tracking capabilities that are GLONASS compatible and therefore supported by GPS, GLONASS, QZSS, and SBSS networks.

If you’re unsure which frequency reference you require, don’t hesitate to reach out. We are also able to manufacture custom units for unique applications.

1PPS Simulated Source-NR3700-PPS

Low Cost 1PPS Synthesized from a Low Noise, stable OCXO

A Source of PPS in GNSS Denied Environments


The NR3700-PPS is a low cost means to have a source of PPS when GNSS GPS is not available. The 1PPS is synthesized from a high stability OCXO offering +-50 ppb/year. The synchronous counter keeps pulse to pulse jitter well below a 1 ns. The pulse frequency and pulse width are factory programmable.

  • 1PPS 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
  • Auxiliary LVDS output
  • Optional 10 MHz sine
  • Other Frequencies available
