Product Overview

The Epsilon Clock™ 3T is a very high performance GPS clock with compact atomic Rubidium oscillator.
 

The extremely accurate and stable time and frequency signals in a compact stand alone unit with low power consumption is ideal as a Primary Reference Source (PRS) or Primary Reference Clock (PRC) for telecom network synchronization.
 

The high performance Rubidium oscillator slaved to the GPS input source offers outstanding accuracy and phase noise. The oscillator in conjunction with the EpsilTime™ smart predictive slaving algorithm mitigates the effects of inherent GPS noise and complies to the most stringent holdover mode requirements if GPS is lost. A high performance OCXO is also available.
 

In addition to the 1 PPS, 4 x 2.048 MHz, and time of day outputs, the E1 option provides 2 x 2048 Kbit/s. An option is available to synchronize to one external 1 PPS.
 

Setup, status, time of day and alarms are accessible via a front panel display and keypad. Selection of all settings including squelch of frequency outputs, G.704 alarm bit, antenna cable delay, choice of time scale (UTC or GPS) are user programmable. Extended status is available through the front panel Man Machine Interface or via the serial line interface.
