• Commercial DSP modules have been tested for their applicability to gamma-ray spectrometry.
• The spectrum quality (energy resolution and peak area) was studied versus shaping parameters.
• The stability of a reference peak count rate versus the total count rate was examined.
• Metrological applications require checking of the DSP performances to assess measurement limits.
Commercial digital signal-processing modules have been tested for their applicability to gamma-ray spectrometry. The tests were based on the same n-type high purity germanium detector. The spectrum quality was studied in terms of energy resolution and peak area versus shaping parameters, using a Eu-152 point source. The stability of a reference peak count rate versus the total count rate was also examined. The reliability of the quantitative results is discussed for their use in measurement at the metrological level.
