Spectratime SRO-100 Rubidium Oscillator

SRO-100 Oscillator Overview

The slim SRO-100 is a smart, low cost GPS/GNSS-disciplined rubidium oscillator (GPSDO), integrating complex synchronization functionality all in one low-cost, super-small package.

It utilizes the patented SmarTiming+® technology to provide a host of timing features, which were previously implemented externally on a separate circuit board. The SRO intelligently synchronizes, disciplines, and controls any primary reference source, such as GPS/GNSS, Cesium, Hydrogen Maser, and T1/E1, at cutting-edge 1ns resolution.
