Femtosecond Clock Synthesizer (FemtoStepper)
The FemtoStepper™ is a high-performance, high-resolution phase & frequency synthesizer. It features an advanced < 100 fs resolution step to control and adjust the output drift of a primary reference clock or standard, such as an active hydrogen maser clock, without changing its behavior. The drift can be automatically compensated through the AutoDrift feature. It is designed for clock ensemble modeling and time & frequency generation from a clock ensemble system. Applications include time generation systems for metrology labs, GNSS satellite navigation systems, and time generation systems for GNSS ground primary time facilities to name a few.
