Abstract :
This paper deals with two different techniques for the establishment of the optimal calibration intervals of cesium atomic clocks. In particular, the intervals obtained using a mathematical model derived from a metrological analysis are compared with those calculated with an iterative technique referred to as simple response method (SRM). The remarkable consistency between the results achieved with these different calibration strategies not only provides an experimental cross-validation of both techniques, but it also allows the definition of two interchangeable criteria to ensure the metrological confirmation of any atomic clock of this type.
