The core timing accuracy of our reference products makes them the ideal back-bone for timing critical measurements. ” How do you know your frequency reference is working properly?” With a completely redundant time base driving an internal frequency counter, you can measure the reference performance continuously and can log that data via the internet for as long as required.

Frequency Reference Redundancy Switch

Dual Channel Redundancy

Novus frequency reference redundancy switches are a quad channel design. Instead of a single pair of signals being switched, the Novus switch handles two separate signal pairs per channel.The most common appliaction is to switch the PPS along with the 10 MHz sine wave in a single 1 ru package. The has built in monitoring or can be driven by an external status signal. Ethernet option reports status as well as remote control.

50 MHz Ultra-Low Phase Noise Locked Reference

50 MHz Ultra-Low Noise Source

The signal source is from a 10 MHz reference that is an ultra-low noise OCXO that can be locked to GNSS or Rubidium or an external reference. The 10 MHz reference drives a diode bridge 5 times multiplier. Both the low noise 10 MHz and 50 MHz are available. The NC7400 can be ordered at 20, 30, 40 or 50 MHz.

Dual Time Base Lab Refererence

Dual Time Base Lab Refererence

The NR8700 offers a laboratory reference with a completely redundant time base as the source for an internal frequency counter. The measured frequency is displayed on the front panel and is also available via an internet port for logging. The unit can also be programmed to send an email if the reference becomes out of tolerance. Now you can explain to the auditor how you know your reference is correct! Unit has dual 10 MHz outputs, NMEA and PPS.

100 MHz GNSS Locked Reference

100 MHz GNSS Locked Frequency Reference

The NR3620-100 offers a laboratory reference featuring a low noise 100 MHz OCXO locked to the GNSS. Low noise combined with high stability. NMEA port and PPS output driven by a 26 channel GNSS receiver. Auto-calibration minimizes long-term drift.
