The new digitizer and analyzer boards make use of the latest versions of GHz analogto-digital converters and the most complex field programmable gate array chips commercially available today. These state-ofthe-art chips have made possible to build digital spectrometers with instantaneous bandwidths up to 1.8 GHz and 8192 spectral channels.}, language = {en} }
