Time interval and frequency standard
GPS-12R/GPS-12RG
Spectracom
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 four models:
* GPS-12 - GPS-controlled OCXO frequency reference giving high stability at a low cost
* 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
Standard configuration includes three front-panel outputs: two switchable 1.544 MHz (T1) or 2.048 MHz (E1) outputs; and one selectable 10 MHz pulse/1-pps time reference. Optional outputs include 1,5 and 10 MHz outputs for metrology purposes, E1/T1 clock and data outputs for telecom and 13 MHz output for radio base station test. An external 1-pps disciplining input is another option. The ultra-stable, built-in Rubidium atomic clock oscillator offers excellent frequency and time stability, whether in GPS-disciplined mode, or in hold-over mode. Configurable alarming provides easy to read urgent and not-urgent alarms for loss of GPS, loss of antenna connection, hardware failures, and more. User settings and display are selectable for six languages.
