absolute frequency metrology. Frequency comb metrology in the nearinfrared beyond µm has principally been pursued with µm Er:fiber combs [7], for example to measure the frequency of the intercombination line of the Ca transition at THz [8] or .
Microsemi Rubidium Frequency Standards provide costeffective, compact, and long lasting stable reference signal equipment for precision test and measurement applications, telecommunications, advanced communications, navigation and targeting systems.
We have developed a ringcavity resonator that can be used to measure the absolute frequencies of optical transitions with an uncertainty below 40 kHz. The length of the resonator is calibrated against a reference laser locked to the D2 line of 87Rb, the frequency of which is known with 6 kHz accuracy.
The warmup of the Model Rubidium oscillator is even faster, taking only 10 minutes to reach as close as 4x1010 from the final frequency. For protection during transport and storage, there is .
A rubidium standard or rubidium atomic clock is a frequency standard in which a specified hyperfine transition of electrons in rubidium87 atoms is used to control the output frequency. It is the most inexpensive, compact, and widely produced atomic clock, used to control the frequency of television stations, cell phone base stations, in test equipment, and global navigation satellite systems like GPS .
At Precise Time and Frequency we strive to offer our customers frequency reference and time synchronization solutions tailored to meeting performance requirements at minimum cost.

Apr 01, 2019· TimeProvider 1000 distribution unit which based on the input reference signal and the internal Rubidium or Quartz clock modules provide up to 32 x E1/ output signals per device. The device is upgradable with software NTP function for the timing distribution in Ethernet networks.
It provides stable and reliable performance, with an estimated 20 year aging of less than 5 × 109 and a demonstrated rubidium oscillator MTBF of over 200,000 hours. The FS725 is an ideal instrument for calibration and RD laboratories, or any application requiring a precision frequency standard.
Jun 10, 2015· There are three different types of timing signals for dependable synchronization: frequency, phase, and time. Frequency can be supplied by an individual clock, such as a commercial (atomic) Cesium or Rubidium standard, though practicality drives the use of local oscillators that require calibration and active reference signals.
