Real-Time Digital Pulse Processor (DPP) and Scintillation Detector Spectrometer in One Package. The nanoMCA-SP is a digital pulse processing multichannel analyzer that has a built-in preamplifier in addition to everything the original nanoMCA device has to offer. This low-power, small,  and lightweight device is perfect for portable applications using scintillation detectors such as LaBr, NaI(Tl) and others.

The nanoMCA-SP is a state-of-the-art small, low power, high performance digital MCA with built-in preamplifier, featuring:

  • Built-in preamplifier for scintillation detectors coupled to photo-multiplier tubes
  • Full featured 80MHz Digital Pulse-Processing (DPP) Multichannel Analyzer (MCA)
  • Two analog inputs supporting reset and resistive feedback preamplifiers and a photomultiplier anode sensing built-in preamplifier
  • Pulse-Height Analyzer (PHA) mode allows for height analysis using analog shapers
  • Free labZY-MCA software for device configuration, spectra acquisition, and spectrum analysis using the 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)
