An Automated System for the Electrical Measurements of a Rectifier Circuit Using SCPI

Abstract

This paper presents an automated method to perform the electrical measurements of a singlephase full-wave rectifier system having a constant load voltage. Using a combination of SCPI commands and MATLAB for the purpose of adjusting the desired measurementsettings of an oscilloscope, transferring data from the oscilloscope to MATLAB, and processing data in this high-level language, then finally offering the measurement results in a proper presentation. The process utilizes the brief nature of the SCPI commands and the programming environment that MATLAB provides, and their employment together offers convenient and accurate readings of the implemented system. Besides that, the approach provides an example of an alternative technique to the traditional method used when controlling various instruments including function generators, spectrum analyzers, DC power supplies, and other instruments that support SCPI common commands. All the hardware components that are necessary for the proper execution of the system working conditions and accurate measurement acquiring are also presented in this research paper.
