We present the first results of a simulation oriented to obtain synthetic differential light curves; which contemplate situations with different atmospheric and instrumental conditions; looking foward to obtain real cases. Our aim is to test the different statistical tools that are used in the analysis of variability of active galactic nuclei (AGNs). In particular; we analyze the behaviour of these synthetic light curves taking into account the C and F statistics. The present work is a continuation of the analysis of a 39 AGN sample; studied before by 1999A&AS..135..477R 1999A&AS..135..477R and 2002A&A...390..431R 2002A&A...390..431R; and re-analyzed by 2012BAAA...55..377Z 2012BAAA...55..377Z. Results from the previous work are compared with those obtained in the simulation.
