A program for processing the digital images of analog oscillograms at pulsed measurements of the current-voltage characteristics of semiconductor materials and devices in the region of high electric currents is presented. The processing of digital images in this program bases on scanning of coordinates and allows measuring the instantaneous voltages and currents with a relative error of no more than 1%. The program is created using the languages HTML5, CSS3, JavaScript and Canvas technology. The software environment for program run is the Internet browser.

Web application is described that allows, by scanning digital images of analog oscillograms of voltage and current pulses, to measure with high accuracy the volt-ampere characteristics of semiconductor materials at high electric currents. The application allows measuring voltage and current with a relative error that does not exceed  1%.
