An Innovative Architecture for Resilient Timing

Combining a high-precision atomic clock, GNSS-satellite-based timing and a trusted timescale, the virtual Primary Reference Time Clock (vPRTC) is a highly secure and resilient network-based timing architecture that has been developed to meet the expanding needs of modern critical infrastructures.

53100A Phase Noise Analyzer

The 53100A Phase Noise Analyzer can be used for measuring precision atomic clocks, quartz and other high-performance oscillators up to 200 MHz. The intuitive PC-based interface makes it easy to acquire frequency stability measurements including Allan Deviation (ADEV), 相位噪声, 是噪音, 抖动测量和更多. 小号的, rapid acquisition time and backwards compatibility with the legacy 5120A series of 相位噪声 analyzers make the 53100A easy to integrate into existing test infrastructure or for it to serve as the workhorse for high-performance metrology applications.

Better Undersea Sensing with our CSAC

Sensors employed in undersea applications rely on precise timing to be effective. 然而, because time from GNSS is unavailable underwater, these sensors have generally relied on Oven-Controlled Crystal 振子 (OCXOs) for stable and accurate time stamping within the sensor. Now, these sensors have a better option: our CSAC. OCXOs相比, our CSAC maintains higher accuracy for longer periods of time, uses less power and maintains a more stable frequency despite the wide variations in temperature that these sensors encounter.
