In this paper, two different techniques are considered in order to determine the optimal calibration interval: the intervals that are obtained using a mathematical model and those that are calculated with an iterative technique referred to as a simple response method. It is shown that both techniques provide useful information for an accurate calibration of a rubidium frequency standard. The authors have chosen this example because the degradation of its calibration condition can be modeled by the use of a quite complex stochastic process called the integrated Brownian motion, which is also of interest in other different contexts. The rubidium frequency standard is diffused in industrial calibration laboratories.

Abstract
In this paper, two different techniques are considered in order to determine the optimal calibration interval: the intervals that are obtained using a mathematical model and those that are calculated with an iterative technique referred to as a simple response method. It is shown that both techniques provide useful information for an accurate calibration of a rubidium frequency standard. The authors have chosen this example because the degradation of its calibration condition can be modeled by the use of a quite complex stochastic process called the integrated Brownian motion, which is also of interest in other different contexts. The rubidium frequency standard is diffused in industrial calibration laboratories.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
