This project is about the development of a sotware interface for controlling two different EMC tests, one is for controlling the devices that measures electromagnetic disturbances and the other one is for manipulating the devices that are used in a susceptibility to radiated electromagnetic interferences test. The different sections that are contained in this thesis explain the procedure followed to develop the software interfaces, that is, the steps which were basically used for the device initialization or communication setting up, parameters configuration, data acquisition, data conversión, data plotting, data reading from a file and file creation for savin results.
