PRS10 Rubidium frequency standard OEM Module

05 February 2008

Available in the UK from Lambda Photometrics Ltd; the Stanford Research PRS10 is a 10MHz Rubidium (Rb) disciplined frequency source with ultra-low phase noise, excellent stability and low aging rate. It is an ideal component for use in any OEM or end-use application requiring a stable precision low noise frequency standard.

PRS10

Key Features:

  • 10MHz output
  • Very low phase noise
    (<-130dBc/Hz at 10Hz)
  • Time tags or phase-locks to a 1pps input
  • 72 hour Stratum 1 level holdover
  • RS-232 interface for diagnostics, control and calibration
  • Optional break-out
    connector board
  • 20 year Rb lamp life
  • Compact package (50x75x100mm)HWD
    •

Stanford’s unique approach uses the 3rd overtone of a stress-compensated (SC-cut) crystal oscillator to produce an ultra-stable 10MHz output with very low phase noise (<-130dBc/Hz at 10Hz offset). The Rb lamp physics package provides a well defined gas transition reference frequency that is used to discipline the crystal oscillator.

The PRS10 has a very low aging rate (<5 x 10-11/month). Additionally, the system can be phase-locked to an external source such as a 1pps GPS timing receiver, which eliminates the problem of long term aging and frequency offsets.

A 10MHz microcontroller controls all aspects of operation and provides diagnostics, measurement and closed case calibration through a RS-232 interface. The optional break-out connector board gives easy access for DC power, input/output BNC and RS-232 communication connectors.

The PRS10 is part of our range of frequency standards and oscillators, including the FS725 Benchtop Rubidium Frequency Standard, FS710 Distribution Amplifier, SC-10 Ovenised Crystal Oscillator, FS-700 LORAN-C Frequency Standard, SR620/625 Time Interval & Frequency Counters, CG635 Clock Generator and DS series Function Generators.
