This master's thesis presents the development of a program that allows multiple measuring instruments (ITech IT9121, ITech IT6000C, Newtons4th PPA5530, RIGOL DS1000Z, Agilent MSO7034A) to be connected over a LAN network and controlled remotely using a GUI and a custom measurement program. These instruments were used to evaluate a direct voltage converter. Communication standards were analyzed, with VISA being chosen as the most suitable. The programs were developed in Python, utilizing PyVISA for LAN communication. The GUI enables setting converter parameters, monitoring temperature, and managing measurement parameters. Measurement results indicated the expected efficiency of the converter and allowed for comparison between different instruments.
