nanoMCA-II

Ultra Low Noise Real-Time Digital Pulse Processor (DPP) and Digital MCA in One Package. The nanoMCA-II offers unmatched low noise performance using state of the art Digital Signal Processing. It is a more powerful version of the original nanoMCA device, with ultra low-noise analog front-end, three additional input/output channels, higher (125 MHz) sampling frequency, among other features. It is also a perfect match to analog pulse-shapers, replacing old-fashioned spectroscopy ADCs and MCA buffers.

Check out how the nanoMCA-II compares to Amptek and Ortec devices.
