Work is devoted to development of the program of the digital data processing, received at test of the power transformer by a method of nanosecond impulses with the *.csv expansion. Programming was carried out in the environment of Lab View. The step-by-step description of work with the program, advantages of the developed program and results is considered. The way of data processing is presented to comparison with the program in the environment of MathCAD. Inconvenience of using of MathCAD for this processing is in need of preliminary manual processing of initial files with the *.csv expansion, received from an oscillograph that extends time of processing of experimental data and demands possession of the MathCAD program. Operating condition of the program developed in Lab View, the identical step of sampling of processed signals is. Visualization of oscillograms is carried out by introduction of initial files with the *.csv expansion in the corresponding window of the program and button pressing start-up. Processing of oscillograms allows to equalize initial time of the processed impulses having any shift from each other, and to receive a difference of the processed oscillograms in a separate window. The description of procedure of preservation of the processed figures and obtaining schedules of impulses also is provided in work with the name of abscissa axes and ordinates.
