A prototype board based on FPGA for data acquisition in Nuclear Spectrometry is given as part of a continuing project. The FPGA based system, perform functions such as dead-time control, detection and management of stacked pulses during acquisition and the storage of spectra. This device allows viewing digital signals and accurate measurement of the pulse high (energy). The graphical interface for the control of the acquisition card is a LabVIEW virtual instrument. Spectral results were compared with spectra produced by a commercially available spectrometer and indicate that further improvement in energy resolution is needed. [ABSTRACT FROM AUTHOR]
