Description
Summary:An multichannel analyzer has been designed, and its performance has been evaluated. The multichannel analyzer is embedded into a Field programmable gate array. The design incudes the virtual instrument in order to hand and to visualize the pulse height spectrum. Two commercially available multichannel analyzers using a NaI(Tl) and HPGe detectors were used to obtain the pulse height spectra of 137Cs, 60Co and 152Eu sources and were compared with the pulse height spectra obtained with the embedded multichannel analyzer, being alike the spectra obtained with the commercial multichannel analyzer. Our design is smaller, low cost and it has options to add other features. •An MCA embedded into a FPGA was designed, built and evaluated.•To hand and visualize the spectra a VI was designed.•The obtained pulse height spectra are alike to spectra measured with commercial MCA.
