Stanford Research PRS-10 Low Phase Noise Ruofferium Frequency Standard.

I’m offering a Stanford Research PRS-10 Ruofferium Frequency Standard complete with heatsink and connecting cable. The PRS-10 is in fine cosmetic and operating condition as shown by the photos. Note in particular the lack of any alarm conditions on the screen image of the RBmon10 monitor and control program.


A CDROM with the PRS-10 data sheet, operating and service manual, and a copy of the RBmon10 Windows application is included.

This is what is for sale in this sale:

Ø PRS-10 Ruofferium Frequency Standard.

Ø Heat sink.

Ø Wire bundle cable with plug to connect to the PRS-10 and terminated in an 8-pin header. This cable does not include 1PPS in and out signals. The 1PPS input and output signals are on the plug connecting the cable to the PRS-10 and can be easily accessed as shown in one of the attached photos. The unmodified cable included in this sale is shown rubber banded to the PRS-10 in several photos.

Ø CD ROM with documentation and RBmon10 monitor/control program. This program should run on most any reasonably current Windows machine.


The PRS-10 needs a heat sink for benchtop operation. One of the attached photos shows the PRS-10 heat sink at 110F in a 72F room. The PRS-10 gets warm. The heat sink shown is included in this sale.


You will need to add a 24 VDC supply rated to provide 2.5A start-up current while the PRS-10 internal physics package and crystal oven heat to operating temperature. Operating current drops to about 0.7 A once the reference is at a steady state.


Several photos show a Stanford Research PRBB (PRS-10 Breakout Board), various coaxial cables and instrumentation used to test this PRS-10 prior to offering it for sale. The PRBB IS NOT included in this sale, but was used to access signals for test. I will be listing the PRBB for sale in the next day or so. A second home built breakout board supporting up to four PRS-10 is shown in one photo, but IS NOT included in this sale.


This is a clean and properly operating PRS10. I've had it sitting on a shelf in myhome shop for a few years and I simply need to clear space. The RBmon10 screen shots were taken yesterday, February 13, 2021, when I powered the unit for test prior to posting. Check my response for additional confidence!


To confirm proper operation, the PRS-10 10 MHz output was compared with a second GPS disciplined clock.PRS-10 initial start-up was without supplying an external GPS timing receiver 1PPS. The Rb stabilized within 30 minutes at about 10,000,000.0088 Hz (a single 1-second sample) – again, without supplying an external 1PPS.


Adding an external 1PPS from a Motorola timing receiver brought the output to 10,000,000.0003 for a 1 second sample and 9,999,999.99975 for 1,000 1-second samples averaged… again with respect to a second GPS disciplined reference.
