nanoMCA-II

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. 

The nanoMCA-II is a state-of-the-art small, low power, ultra-high performance digital MCA, featuring:

  • Full featured 125MHz Multichannel Analyzer (MCA) based on Digital Pulse-Processing (DPP)
  • Two analog inputs supporting reset and resistive feedback preamplifiers and user-shaped pulses, including pulses from analog spectroscopy amplifiers
  • Pulse-Height Analyzer (PHA) mode allows for height analysis using analog shapers
  • Free labZY-MCA software for device configuration, spectra acquisition, and spectrum analysis
  • Built-in Trace Viewer, the most advanced detector signal exploration tool
  • Automatic functions: thresholds, pole-zero, input polarity, inhibit polarity
  • Built-in coincidence logic with delays and coincidence window generator
  • Convenient and flexible connectivity
    • I/O: Single mini USB connector also power source
    • Power: USB, mini wall adapter, or optional battery
    • Device interface: Wired or wireless (USB, Ethernet, WiFi, Bluetooth)
  • Exceptional temperature stability
  • Small size (92 mm x 38 mm x 25 mm) and low power (850mW typ)
