Real-time measurement, especially in analyzing the electrical waveform, is necessary to explore physical phenomena. Virtual instrumentations have been studied for various applications such as water existence, characterization and modeling of electrical impedance, and electrical resistivity. This research presents software, a Graphical User Interface (GUI) was programmed in a LabVIEW environment that has been implemented to monitor and analyze the square wave. A pulse generator generated an electrical signal. The alteration of the current and potential wave presented in the measurement is used to determine resistivity. Additionally, the GUI can be proposed to investigate the electrical properties of materials in the subsurface using the electrical method.
