Feb 02, 2012· Long time averagin method with two HP Z3801 one HP/Symmetricom 58503A (it is nearly same as Z3801) and HP53131A for statistical analyze so that I can think if can trust or not. Also I can follow with some poor Trimble Thunderbolt and With careful long time method this can easy go to this accuracy. If I see some disturbance in stability I just put this follow to garbage and take agen.

Determining g-factors in Rubidium-85 and Rubidium-87 using optical pumping Will Weigand, 1Adam Egbert, and Hannah Sadler University of San Diego (Dated: 25 September 2015) In this paper we quantify the Zeeman e ect in rubidium.
The chassis now hosts the LPRO rubidium oscillator, a frequency lock indicator, numerous meters and the Condor linear power supply. Admittedly its boat-anchor size compared to the compact frequency standards in this thread. Nonetheless it meets my DIY objective to be a portable and make use of recycled parts.
A rubidium frequency standard is a very versatile atomic clock with excellent short term frequency stability and it is relatively small in dimensions and light in weight. It is a passive atomic clock i.e., in this atomic clock a VCXO frequency is locked to the ground state hyperfine transition frequency of Rb87 atoms. The atomic resonance serves

FREQUENCY vs. TEMPERATURE: Frequency variations due to ambient temperature variations can easily swamp other sources of instability for a Rb frequency standard operating in a real life environment. Therefore, special attention was given to frequency stability vs. temperature in these designs. Figure 5 and 5 show typical performance data for FE ...
The GPS10R/RB are 10 MHz, GPS disciplined, rubidium frequency standards. They combine the short-term stability of an atomic rubidium oscillator with the long-term stability and traceability of the Global Positioning Service (GPS) set of satellites. The GPS10R/RB achieves short and long-term frequency accuracy of parts in 10-13. Thus the GPS10R ...

Figure 2. Long-term performance data (one year) from four rubidium frequency standards. period, whereas a $35,000 cesium will probably be accurate to within a few parts in 1013 or better. However, many cal labs adjust their rubidium standards on a regular basis, and this allows them to maintain average frequency to within a few parts in 1011
frequency stability requirement can be stated as u (T=T) c 10 where T is the interval in seconds between the time comparison at two remote locations (trip time). From this equation and fig. 1 it is clear that the rubidium clock is basically capable of providing time comparisons to better than 0.1 ps for trip times out to many hours.
Manufacturers of rubidium frequency standards sometimes use a crystal frequency that is an exact sub-multiple of the hyperfine transition frequency in order to simplify the design of the RF frequency synthesizer. Some designs use a DDS synthesizer, clocked by the crystal, to generate the 10 MHz output.

Rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre. Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named
The article provides some technical information about the Lucent RFG-M-RB rubidium frequency reference. Analysis of the parts of the schematics was performed and several circuits built to improve quality of the RF reference signals. This information may also prove useful for repair or restoration of the hardware.
Stability and Noise Performance of Various Rubidium Standards Among the well-known time and frequency standards from Hewlett Packard and other vendors, the HP 5065A rubidium vapor frequency standard offers the best medium-term frequency stability of any device that the casual (or even hardcore) "time nut" is likely to encounter.
Atomic physics sets the standard for stability, accuracy and range of applications in precision frequency reference clocks worldwide. Our Rubidium, SAW and quartz oscillators support more military communications, satellite ground stations, and test and measurement applications than any other precision frequency references in the world.
