A four-channel VERSAmodule Eurocard (VME) with 14 bit, 80 MHz digitizers and powerful on-board processing has been designed, built, and used in tests of digital pulse processing techniques for gamma-ray tracking. This paper explains the background, describes the VME card (known as the GRT4) and presents a 64-channel GRT4 digitizing system which was used to instrument two segmented Germanium detectors during in-beam tests. Results obtained using the GRT4 card are presented as well as some applications. Index Terms--Digital signal processing, digitizer, field programmable gate arrays (FPGAs), gamma-ray spectroscopy detectors, germanium radiation detectors, pulse shape analysis (PSA), segmented detectors.
