GPS-12R
Portable GPS Frequency Standard
Accuracy, High-Stability and Performance
The GPS-12R frequency standard offers traceable Cesium-like stability at a very attractive price. Synchronized to the GPS satellite system, the GPS-12R provides both short and long–term time and frequency stability, assuring precision and accuracy.
We offer the following models:
- GPS-12R - GPS-controlled Rubidium frequency reference giving near-Cesium stability
- GPS-12R/HS – high-end model including a high-stability Rubidium for optimum phase noise performance
- GPS-12RG – Glonass/GPS-controlled High-stability Rubidium reference
Ease-of-operation
Unlike other blank-front-panel instruments that demand a remote PC interface to control and monitor the operation, the GPS-12x has an intuitive user-friendly front-panel operation. Menu selections are made on the large graphic LCD screen, and all relevant instrument status like time and position, satellite data etc can be displayed. To further enhance the ease-of-use, the menu is selectable in 7 different languages, including Russian, Chinese and Japanese.
An optional PC SW enables also remote control and monitoring of all GPS-12x menu functions.
Portability
Where AC Mains voltage is not available, the internal battery operation provides oscillator stability during transportation or in field applications. This feature is ideal for telecommunications requirements such as SDH/PDH/SONET Analyzers, wireless base stations, or public utility field applications where lightweight portability with zero warm-up time and full stability is essential.
Applications
As an in-house reference standard for calibration or as the master clock for test instruments, the GPS-12R provides a continuous stable and accurate frequency standard. The GPS-12R/HS with optional 1, 5, 10 MHz outputs is the ideal precision reference standard for use in; metrology, radar antenna array systems, public utilities, and the electronics industry. The optional battery provides increased efficiency of the GPS-12 family when transportation between work stations is required.
For precise time synchronization and editing of Digital Video Broadcasting/Digital Audio Broadcasting systems; broadcasters and post-production facilities look to the GPS-12R to deliver the ultra-stable master clock required to sync SMPTE time-code generators.
GPS-12RG Portable GLONASS/GPS Rubidium Frequency Standard
The Pendulum GPS-12RG Portable Reference clock is an ultra-stable GLONASS and GPS-disciplined Rubidium reference, targeted for both laboratory and telecommunications applications. The combined use of GPS and Glonass satellite constellation, ensures improved satellite visibility, especially important in urban areas where tall buildings may obstruct the sky view.
