REF-DS-10 is an high-stability signal generator of Time (PPS) and Frequency (10 MHz), formed by two independent transport system of the time/freq reference, implemented in two separate extractable modules. Both modules allow the tuning of high-quality oscillator (OCXO). The equipment generates 10 high-precision signals both for Time (PPS) and Frequency (10 MHz).
Main Peculiarity of REF-DS-10 is that in the extractable modules, in addition to the traditional GPS receiver, it's possible to choose as alternative also other kind of devices able to generate the time signal: ie. Satellite systems, Optical Fiber, E1/T1, according to the synchronization source that should be used. Assuming the possibility both to use secondary sources as control tool of the main, and to ensure the maximum precision in the crucial transmitting sites.
There is no logic of exchange between the two sources, as these can work in combination. In this way you do not get to put any gap in output in the references of time / frequency where one or both sources should not longer work properly or you were to break down, reducing the complexity of the parameters set by the user and at the same time being able to improve 'reliability of the equipment. Project staff of Digital Instruments, has also presented special care so that individual modules are removable and replaceable in a few moments.
