The Symmetricom 8130A is an enhanced version of our popular M-100 rubidium oscillator. This modern, off-the-shelf militarized rubidium oscillator is ideal for use in tactical applications where shock, vibration, humidity and other environmental factors are a challenge. The circuit boards are conformal-coated for moisture resistance, and special precautions are taken for improved shock and 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 Symmetricom 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 Symmetricom 8130A minimizes maintenance requirements. The Plastic Encapsulated Microcircuits (PEM) devices are subjected to a proprietary qualification process for improved reliability.The 8130A provides a stable frequency with good short and long-term stability, and excellent overall performance. The unit includes an RS-232 digital interface for monitoring and frequency adjustments. Suitable applications include ground, shipboard and airborne navigation, timing and other tactical applications that need the performance level associated with rubidium technology in a militarized off the- shelf package
