Product Overview
The Epsilon Clock™ 3S 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 chassis (2U high – 19" wide) suits a comprehensive range of applications where excellent accuracy and stability are required.
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. Furthermore, the 10 MHz frequency reference is cycle locked to the 1 PPS, meaning that there are always exactly ten million cycles between 1 PPS occurrences. This unique feature is essential to avoid phase jumps and wander between time and frequency references.
In addition to the 1 PPS, 4 x 10 MHz, and time of day outputs, many distribution options are available including 1 or 5 MHz, IRIG-B, STANAG 4430 (Havequick), frequency synthesizer, 2048 kHz and 2048 kbits/s, and 3 additional 1 PPS. 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, antenna cable delay, choice of time scale (UTC or GPS) are user programmable. Commands are password protected for security. Extended status is available via the serial line interface. Optional EpsilWin32™ software achieves complete remote control and supervision.
