The Quartzlock model A10-Y is an OEM, high-performance, ultra low noise, rubidium oscillator frequency reference which uses Quartzlock phase-locked loop (PLL) and direct digital synthesis (DDS) clean-up loop technology. It has a noise floor of -172 dBc/Hz.

Typical applications include but not restricted to Security, Low noise instrumentation reference, Radar navigation, RF & Microwave test solutions and Secure communications.

The use of ULN rubidium oscillators enables Weak signal detection, Low error rates, Higher radar sensitivity and Higher definition in MRI imaging systems.
