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.

Single Channel 10MHz Lock-In Amplifier NR3620-L
NR3620-L-ID-3

10 MHz Lock-In Amplifier

Restores Frequency Reference Phase Noise and Maintains Synchronization

NR3620-L

Many systems require more than one frequency reference. The NR3620-L and NR2110-L allow an existing precision frequency reference in a system to be restored by locking a low noise OCXO to reference. The phase noise will be restored and the clean-up OCXO will be synchronized to the system reference. This configuration allows considerable flexibility between the source and the output. Factory configurable from 1 MHz, 10 MHz to 50 MHz.

Available in either rack or modular chassis.

AC or DC powered.

Configurable over the frequency range of 1, 10 MHz to 50 MHz sine wave.

Six Channel Ultra Low Phase Noise 10MHz Lock-In Amplifier

Lock In Amplifier Restores Phase Noise and Maintains Synchronization

NA2306L

Ultra-low phase noise six channel lock-in amplifier can restore a marginal reference to low phase noise state without giving up timing synchronization.  To minimize vibration induced phase noise artifacts from fans and other sources, the OCXO is vibration-isolated.

  • OCXO holdover.
  • OCXO stability 5 ppb/day – 50 ppb/ year.
  • Frequency change from lock state < 10 ppb.
  • Auto-Calibration continually preserves OCXO compensation coefficients.
