RAFS
Rubidium Atomic Frequency Standard.
 

RAM
Random Access Memory.
 

Rectangular wave
An output waveform which is characterised by having short rise and fall times and stable at one of two flat or fixed amplitudes for most of each cycle. It may be specified as TTL or HCMOS output.
 

Reproducibility
With respect to a set of independent devices of the same design, it is the ability of these devices to produce the same value. With respect to a single device, it is the ability to produce the same value and to put it into operation repeatedly without adjustments.
 

Resolution
The degree to which a measurement can be determined is called the resolution of the measurement. The smallest significant difference that can be measured with a given instrument. For example, a measurement made with a time interval counter might have a resolution of 10 ns.
 

Retrace
Retrace limits the accuracies achievable with oscillator in applications where the oscillator is on-off cycled.Typical Rubidium retrace specifications: < 5 x 10-11 within 1 h after 24 h off. This one of the main advantages of a Rubidium oscillator.
 

Ringing
See overshoot.
 

Rise/fall times
A measure of the sharpness of the edges of a rectangular wave form. It is usually specified in units of time (nano-seconds) from 10% to 90% of the rated output voltage.
 

RMO
Rubidium Master Oscillator.
