Análisis de la Desviación de Allan en Osciladores Internos de Referencia en Equipos de Laboratorio Mediante El Uso de Labview

Abstract

Today the industrial sector presents the need to have the electronic equipment properly calibrated, since the processes in which they are used require to guarantee the reliability and correct operation of the instruments; this is achieved through a verification and calibration process. The solution proposed was to develop a software that allows the capture of data of the oscillator of a team based on technical information regarding the analysis of the stability in the time. During the execution time, a series of steps were carried out that allowed the operation of the project; First, the study of methods, procedures and characterization of equipment to be used for the communication process was carried out, to be clear the best method for data capture, followed by an algorithm developed in LabVIEW [1] in which, A communication was made with the electronic equipment which will be calibrated; The Allan deviation method [2] was used to calculate the stability of the data acquired according to the "GUÍA TÉCNICA SOBRE TRAZABILIDAD E INCERTIDUMBRE EN LA METROLOGÍA DE TIEMPO Y FRECUENCIA", At the end of the calibration procedure an Excel file was generated, in which it was possible to compare the data obtained with the previously used software and it was concluded that the developed interface presents a smaller deviation in the time The software used previously, in addition the quality in the data acquisition was improved.
