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.

10 Channel PPS Source - Rubidium Holdover Option NR2310D-PPS

10 Channel GNSS Locked 1PPS Source with OCXO or Rubidium Holdover

10 Channel 1PPS source with < 1 ns skewing


Ten transient and fault protected 1PPS outputs with < 1 ns of channel skewing (typical < 200 ps). 26 channel high-sensitivity, multi-GNSS receiver. supports TRAIM and various position modes, allowing it to output accurate and robust 1 PPS synchronized to UTC time. Supports GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multi-path Mitigation functions. Each channel is monitored and status displayed on the front panel. Built-in self-test drives a signal that can be tied into an alarm panel.  Rubidium holdover option holds PPS drift to less than 0.5 usec/hour ideal for GPS unstable environments.10MHz frequency reference output available to stabilize local oscillators.

● Ten fault and transient protected outputs.

● Ten channels frequently eliminate the need for a distribution amplifier.

● Channel skewing < 1 ns. (Typically < 200 psec)

● Drives 3.3 Vdc LVCMOS or 5 Vdc into 50 Ohms
