Availability Made to order

Overview

The Stanford Research Systems FS725 is a compact half-width 2U frequency standard that integrates a rubidium oscillator, distribution amplifiers, and precision power supply. It provides stable and reliable performance with an estimated 20-year aging of less than 5 x 10-9, making it ideal for calibration laboratories, research facilities, and applications requiring precision frequency references.

Key Features

  • Two 10 MHz and one 5 MHz sine wave outputs
  • Exceptionally low phase noise below -130 dBc/Hz (10 Hz offset)
  • 1 pps input and output for GPS synchronization and Stratum 1 performance
  • Built-in distribution amplifiers supporting up to 22 outputs
  • Rubidium oscillator MTBF exceeding 200,000 hours
  • RS-232 interface with Windows software for monitoring and control
  • Two status alarm relays for lock and synchronization indication
  • Compact 2U rack-mount form factor

Applications

  • Calibration and R&D laboratories
  • Precision frequency and timing standards
  • Electronic compliance and EMC testing
  • Phase and timing sensitive measurements
