Resumen
In this work we developed two real-time acquisition computer systems, for data acquisition in Electron Paramagnetic Ressonance Experiments. In both, a high degree of freedom was kept in the measuring instruments configuration and progrtamming, whiti the sim of making easy a future reassignment to other experimental technics to be installed in the laboratory. One of the systems is an improves version of the so called Passive Monitoribs System and was built in such a way that it can be used in conjunction with the normal operation mode of the spectrometer. The other system incorporates, in addition to the data acquisition facilities, an step motor based gear to drive the sweep of the magnetic field. Furthermore, a large program was also developed to facilitate the processing of the spectra and their transportation to other computers.
