All-in-one Gamma Spectrometer with digital signal processing is applicable for HPGe detector spectrometric pulses registration, amplification, digital filtration and gamma-ray spectra registration. All-in-one Gamma Spectrometer is designed as one integrated monoblock being identical to standard laboratory detection unit with inbuilt preamplifier, however it has inbuilt MCA, HV supply, etc.
