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.

Modes of operation - PHA (pulse height analysis), result is a histogram of pulse height. - MCS (multi channel scaling): registers number of counts in subsequent time intervals. - MCS mode allows to acquire an integral PHA spectrum in parallel to the MCS acquisition. - LLD / ULD settings are supported in both PHA and MCS mode. | |
