Rubidium Frequency Synthesizer

Rubidium Synthesizer. Introduction - Enter '0' as the frequency to turn the generator output off. - Press ESC to exit the program. RUBY4 uses a setup file (RUBY.SET) to define the serial port, the calibration frequency and the calibration command value. By playing with this last value, you can effectively over-ride or correct the internal

Quartzlock

Rubidium Frequency Standards. A Rubidium frequency standard owes its outstanding accuracy and superb stability to a unique frequency control mechanism. The resonant transition frequency of the Rb 87 atom (6,834,682,614 Hz) is used as a reference against which an OCXO output is compared.

RF Mixers

To produce a new frequency (or new frequencies) requires a nonlinear device. In a mixing process if we want to produce an output frequency that is lower than the input signal frequency, then it is called down-conversion and if we want to produce an output signal that is at a higher frequency than the input signal, it is referred to as up

Tactical Rubidium Frequency Standard (TRFS)

The VCXO output frequency of 10 MHz is tightly controlled by a servo loop with a 100 Hz bandwidth. The rubidium resonnance signal is detected by a phase-sensitive technique using sinusoidal modulation. Five multilayer PC boards are used along with discrete components. The TRFS will mount directly onto a platform without external vibration

A rubidium standard or rubidium atomic clock is a frequency standard in which a specified hyperfine transition of electrons in rubidium-87 atoms is used to control the output frequency. The Rubidium Crystal Frequency Standard market was valued

Measuring The Accuracy Of A Rubidium Standard

May 28, 2015A rubidium standard, or rubidium atomic clock, is a high accuracy frequency and time standard, usually accurate to within a few parts in 10 11.This is still several orders of magnitude less than some of the more accurate standards – for example the NIST-F1 has an uncertainty of 510-16 (It is expected to neither gain nor lose a second in nearly 100 million years) and the more recent NIST-F2

The LPRO

Sep 15, 2019Second hand market is now flooded with old decommissioned rubidium standards pulled out of scrapped telecommunication equipment. There are a lot of chooses like the FE-5680A-10MHz or the FE-5650A. Some of those even come with programmable option (Option 58) that allows the user to program his own frequency.

Slew Rate Calculator

So the first calculator calculates the minimum slew rate that is necessary to output a certain voltage at a certain frequency. Say, we want to output 10V at 25MHz. Plugging this into the formula, slew rate=2πfV= 2 (3.14) (25,000,000Hz) (10V)= 1,570,000,000V/s. Converting this to V/μS, we divide this number by 1,000,000 to get 1570V/μS, which
