Rubidium frequency standard: FS725
The FS725 integrates a rubidium oscillator (SRS model PRS10), a low-noise AC power supply, and distribution amplifiers in a compact, half-width 2U chassis. It provides stable and reliable performance with an estimated 20 year aging of less than 5 × 10-9 and a demonstrated rubidium oscillator MTBF of over 200,000 hours. The FS725 is an ideal instrument for calibration and R&D laboratories, or any application requiring a precision frequency standard.
Rubidium oscillator: PRS10
The PRS10 is an ultra-low phase noise, 10 MHz rubidium-disciplined crystal oscillator. The device fulfils a variety of communication, synchronisation and instrumentation requirements. The phase noise of the 10 MHz output is low enough to be used as the reference source for synthesisers. The unit’s short-term stability and low environmental coefficients make it an ideal component for network synchronisation. Its low aging rate makes it an excellent timebase for precision frequency measurements.
