Digital process is implemented in two steps: data-acquisition (a set of measurements) and offline software data-analysis and calculation. The present work shows the basics of the data-acquisition unit (Software Coincidence System – SCS), describes the DCS’ data-analysis process and the initial approaches chosen for the implementation of the software package (Coincidence Analyzing Task – CAT). 152Eu standardization, performed for DCS testing, software expansion and validation, is briefly discussed.1-10openAccesscontrol systemscomputer codesstandardizationradionuclide metrologycoincidence methodsdata analysiscounting techniquesbrazilian cnenArtigo de periódico15510.1016/j.apradiso.2019.1089000000-0001-8407-9833https://orcid.org/0000-0001-8407-9833https://orcid.org/0000-0003-2478-575734.9644.00
