DMCA USB Base 2010

Digital Multi channel Analyzer USB Base Model 2010
The MAC-base consists of a 12-bit CFP multi-channel analyzer and an integrated high voltage generator (0-2000V) and divider to power the photo-multiplier (PMT). It plugs directly onto the PMT and can be powered and controlled via USB. The high voltage divider can deliver 100µA DC current and 20 mA pulse current to the PMT anode while maintaining excellent gain stability.The device and all connectors are sealed against water and moisture intrusion. The USB, LAN and GPIO connectors are IP68 watertight connectors.


The DMCA USB base is a PMT plug-in with a digital MCA, embedded high-voltage generator and the active voltage divider. The MCA-base consists of a CFP multichannel analyzer and an integrated high voltage generator and divider to power the photomultiplier (PMT). It plugs directly onto the PMT and can be powered and controlled via USB. The high voltage divider can deliver 100μA DC current and 20mA pulse current to the PMT anode while maintaining excellent gain stability. The device is sealed and specified over a temperature range of -20°C to +50°C.
