Venus Multichannel Analyzer

Venus/Venus-E Multi-Channel Analyzer


Itech's Venus and Venus E are both universal digital Multi-Channel analyzers which are connected directly to the photomultiplier of a NAI, CsI, Lanthanum Bromide or other scintillation detector. They each include a high voltage power supply for voltages up to 2000 V, preamplifier, and 65MHz sampling ADC and digital signal processing electronics.

The Venus and Venus E can be used in the most exacting spectroscopic applications as well as high rate, industrial counting applications. Because of our range of user selectable gain and time constant options, the Venus is easily adapted to all of today’s choices of scintillators.

The Venus communicates with the computer over a high speed (480 Mbits/s) USB 2.0 connection. It is entirely powered over the USB bus.

The Venus-E communicates with the computer via Ethernet. The Ethernet cable supplies all information and power requirements for the Venus-E.
