The Venus/E is a digital spectrometer which is connected directly to photomultiplier of an NAI, CsI, Lanthanum Bromide or other scintillation detector. It includes the high voltage power supply for voltages up to 2000 V, the preamplifier, an 65MHz sampling ADC and digital signal processing.
The Venus/E communicates with the computer over an Ethernet connection. It is powered over PoE. Alternatively, the Venus/E can also be used with an USB connection.
