The low phase noise option provides higher signal-to-noise ratio allowing for improved signal detection in doppler radar systems and in time difference of arrival measurement. It provides excellent overall performance for numerous tactical applications where shock, vibration, humidity and other environmental factors are a challenge.

Symmetricom, Inc. (NASDAQ:SYMM), a worldwide leader in precise time and frequency products and services, today announced a low phase noise option for Symmetricom 8130A, an enhanced version of their popular M-100 rubidium oscillator. This off-the-shelf militarized rubidium oscillator provides excellent overall performance for numerous tactical applications, and excels particularly for systems requiring good phase noise under vibration.

“This enhanced rubidium oscillator’s low phase noise outputs combine long term stability as well as improved short time stability,” commented Doug Lowrie, product marketing manager at Symmetricom. “The low phase noise option provides higher signal-to-noise ratio allowing for improved signal detection in doppler radar systems and in time difference of arrival measurement. It provides excellent overall performance for numerous tactical applications where shock, vibration, humidity and other environmental factors are a challenge.”

The circuit boards of the 8130A are conformal-coated for moisture resistance, and special precautions are taken for improved shock vibration hardening. Use of a filtered power/monitor connector minimizes EMI emissions and susceptibility. Designed for ease of integration into frequency and timing systems, the 8130A offers a smaller size MIL atomic frequency reference with a heritage of over 25 years of proven experience in the design, qualification and production of atomic frequency references.

The long life rubidium lamp and extended crystal oscillator control range of the 8130A minimizes maintenance requirements. The unit includes an RS-232 digital interface for monitoring and frequency adjustments.

Other key features of the 8130A include 1) modern militarized design, 2) 5 and 10 MHz sinewave outputs, 3) ruggedized high performance Rb physics package and 4) internal temperature compensation option.

The 8130A is ideal for use in tactical applications including ground, shipboard and airborne navigation and timing applications where environmental factors are a challenge.

Pricing and Availability

The Symmetricom 8130A will be available October 2005. Pricing begins at $11,500 USD.
