Stanford PRS10 Rubidium Frequency Standard

The PRS10 is an ultra-low phase noise, 10 MHz rubidium-disciplined crystal oscillator. The device fulfills 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.

Features:

• Low phase noise (<-130 dBc/Hz at 10 Hz)
• 72h Stratum 1 level holdover
• RS232 for diagnostics and control
• 20 year lamp life

The PRS10 can time-tag an external 1pps input with 1ns resolution. These values may be reported back via RS232, or used to phase-lock the unit to an external reference (such as GPS) with time constants of several hours. This feature can provide Stratum 1 performance at a very low cost.

The PRS10 establishes a new level of features and performance in atomic frequency standards. Its design provides the lowest phase noise, greatest versatility, and easiest path to system integration of any rubidium frequency standards available.
