Product Overview

The patented Spectracom Ageless Master Oscillators are highly accurate frequency and timing sources. This model uses an Oven Controlled Crystal Oscillator internal reference. See Model 8197B for the Rubidium reference. Outputs are locked to the United States Naval Observatory via the NAVSTAR Global Positioning System (GPS). T-RAIM (Time Receiver Autonomous Integrity Monitor) algorithm detects and disqualifies faulty satellites to maintain the reliability of system outputs.

Spectracom's field-proven Ageless Oscillator technology provides continual automatic frequency control, compensating for aging and temperature drift.

They are ideally suited as a site master oscillator for communication systems. Typical applications include calibration, land mobile simulcast, narrow band land mobile radio, SMR (Specialized Mobile Radio), paging simulcast, satellite/microwave communication links, T1/E1, cellular telephone, SONET and ATM enterprise timing and broadcast radio and television.

In simulcast systems, the precision frequency offset feature minimizes carrier phase cancellation in overlap areas. The CTCSS generator outputs are aligned site to site.

If AC power fails, an optional battery maintains the oscillator at its operational temperature thereby reducing the recovery period by eliminating oscillator warm-up and retrace. In addition, the battery keeps the electronics in standby mode to allow rapid recovery of the GPS 1PPS, Data Clock and Data Sync outputs once power is restored.

Spectracom offers other system components, including distribution amplifiers, frequency synthesizers, clock selectors and clock converters.
