The Proportional Counter Array (PCA) is the primary instrument on board of Rossi X-ray Timing Explorer (RXTE) satellite. It was operated for more than 16 years to detect the time variation of astronomical X-ray sources in the range of 2-60 KeV and provide event information timed to microseconds in different channels with different data modes. This variety makes it harder to analyze such huge data using the standard procedures. In this study, a customized software is proposed to validate the data by considering all necessary precautions before extracting the final lightcurves (LCs) which are used in both spectral and timing analyses. The proposed software is under test by reproducing the results of four well-known objects with (> 3,000 observations) and total exposure time (>5 million seconds). The results showed good agreement with the diagnostic diagrams from literature. However, this code is fast and applies all the standard procedures in one process using one interface.
