Humidity: Up to 95%.
Size: 187.5x124x366 mm without connectors.
Weight: Approximately 10Kg.

Performance Data

Output Signal Frequency: 10MHz or 5MHz with an accuracy of ± 1x10^-12.
Stability (Allan deviation): Ranges from 2x10^-11 at 1s to 3x10^-13 at 100,000s.
Fractional Frequency Deviation: ± 2x10^-12 over the temperature range.
SSB Phase Noise: Varies from -95dBc/Hz at 1Hz to -145dBc/Hz at 1kHz.

Conclusion
The OSA 3030B EUDICS is a highly reliable and precise frequency standard suitable for demanding applications requiring long-term stability and accuracy.

Catalog excerpts

OSA 3030B EUDICS European Digital Cesium Frequency Standard TIME & FREQUENCY Atomic clocks standards are needed to generate highly accurate frequencies. These are typically used as Primary Reference in telecommunications networks, navigations systems, ground stations (LORAN C, GPS, GLONASS, GALILEO, etc…), long wave and medium wave broadcasting stations. Atomic clocks can also be used for specific inertial navigation systems where external “time reference signals” are not available or insufficiently protected regarding transmission risks. Another field of application is for astrophysics, where very high precision atomic clocks can be used for long-baseline interferometers. The Oscilloquartz’s 3030B Eudics is specifically designed and produced with the latest technology to serve these complex applications. Highly compact, the OSA 3030B EUDICS offers a unique set of operational features and performance, including greatly enhanced and easy integration into industrial, professional and time and frequency host systems.
