The following charts represent typical behavior of a Rubidium Standard AR60A, unless otherwise specified. Phase Noise Typical Rubidium Standard AR-60A Allan Deviation Typical Allan Deviation of AccuBeat Rubidium Std. Typical Allan Deviation  of AccuBeat GPS-Rubidium Distribution of Clock Performance at Temperature The following charts show the distribution of frequency offsets from 25°C, which were measured over a large number of clocks. For a temperature range of -20°C to 73°C, about 80% of the clocks offsets are within the range of +1E-10. At 78°C, about 80% of the clocks offsets are within the range of +4E-10. Time Error Typical Rubidium Frequency Standard AR-60A * Initial time error and frequency offset were set to zero.
