Rubidium
Clock - an Atomic Clock
There are mainly three types of atomic clocks. They
are cesium, hydrogen and rubidium. The principle behind
all the three remains the same. Rubidium atomic clocks
are the simplest and most compact of all. The rubidium
clock uses the transition of the rubidium-87 atom between
two hyperfine energy states. The rubidium atoms are forced
to change their hyperfine energy state and then subjected
to microwave radiations to return to their original state.
When the atoms returns to the original state the frequency
of the period of the wave can be used to measure time.
Rubidium clocks are not as stable or accurate as other
atomic clocks. However they are compact and less expensive.
Rubidium element:
Robert Bunsen and Gustav Kirchhoff discovered rubidium
in the year 1861. Till 1920s this element had minimal
industrial use. However the most important use of rubidium
is in research and development primarily in chemical
and electronic applications. Rubidium is a chemical element
in the period table that has the symbol Rb and atomic
number 37.Rubidium is a soft, silvery-white metallic
element of the alkali metal groups. It is one of the
most electropositive elements and it is ignites spontaneously
in air and reacts violently with water.
Temex Time:
Timex Time is a leading global supplier of low-cost
Rubidium clock and GPS- synchronized timing solutions.
In 2005 they introduced plug and play Rubidium timing
designer kit for system designer. Temex Time has also
announced a low-cost Rubidium oscillator, the LCR-900
that creates an affordable solution for mid-end positioning
test and communications applications.
Rubisource T& M- Portable
Rubidium Timing Signal Reference:
This is a portable timing reference based on rubidium
oscillator technology for use in test and measurement
applications. The output signal provides exact timing
information based on the highly accurate and stable rubidium
oscillator inside. The rubidium fast warm-up eliminates
the need for bulky backup batteries.
Rubisource2000:
Rubisource is a low-cost portable timing reference based
on rubidium clock technology. Rubidium clock provides
highly accurate, stable and reliable output. Rubisource
2000 is designed for telecom and metrology test and measurement
applications. It is also a reference source used to enable
fast measurement and testing of the synchronization quality
of PDH/SDH/SONET Digital networks. Coupled with the optional
GPS FC, the range of observation time can be largely
extended to meet specific requirements.
