- Ruggedized Rb oscillators for military applications
- Low-power, low-profile and low-noise variants
Atomic System Clocks
- Cs beam tube with zero frequency drift
- Active hydrogen maser for ultimate short-term stability
- Largest install-base for timekeeping
- Integration into time-scale applications
- Key component of the virtual Primary Reference Time Clock (vPRTC) network-based timing architecture
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.
GNSS Disciplined Oscillators (GNSSDO)
Access the accuracy of the world’s most stable atomic clocks onboard GPS satellites and similar constellations with our GNSS-disciplined oscillators. These self-calibrating modules deliver UTC time and long-term frequency stability to laboratories and mobile applications. The advanced software algorithms are able to acquire and maintain GNSS-lock in dynamic environments while also identifying and mitigating satellite broadcast errors. These modules pair an integrated Microchip MAC or CSAC with proprietary software compensation so they can maintain long frequency and timing holdover in GNSS-denied missions while keeping size, weight and power to a minimum.
53100A Phase Noise Analyzer
Introducing the 53100A Phase Noise Analyzer 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), phase noise, AM noise, jitter measurements and more. The small size, rapid acquisition time and backwards compatibility with the legacy 5120a series of phase noise analyzers make the 53100A easy to integrate into existing test infrastructure or for it to serve as the workhorse for high-performance metrology applications.
