Spectratime RBSource-1500

RBSource-1500 Overview

The RBSource™ is a low-cost, high-performance rubidium reference disciplinable to an external GPS/GNSS standard, all in a compact 19" 1U package.

It uses an auto-adaptive SmarTiming+® technology, disciplining the GPS/GNSS reference up to 100,000 seconds at 1ns resolution, depending on the GPS/GNSS 1PPS reference noise and signal-impairment level.
