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.

Six Channel 10 MHz GNSS GPS Disciplined Oscillator with External Synchronization Capability to 1PPS or RF

Six Channel 10 MHz GNSS GPS Disciplined Oscillator Frequency Reference with External Synchronization –

Six Channel Frequency Reference Locks to GNSS or External 1PPS or 10 MHz

NR3626-OG

The NR3626 is a high-performance 10MHz frequency reference that is driven by a low phase noise SC cut OCXO disciplined by a 26 channel GNSS receiver. The 10MHz outputs are 13 dBm while the 1PPS outputs can be 5 or 3.3 Volt logic levels with the capability of driving a 50 Ohm load. In addition to the built in GNSS GPS receiver, there are an external 10 MHz and external 1PPS input that can be used to discipline the reference. The priority for each disciplining signal is software settable between the three signal sources.
