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.
