  nanoDPP 微型数字脉冲处理器

  I. FEATURES

  Ultra small size high-performance Digital Pulse Processor (DPP).

  16k channels utilizing smart spectrum-size technology -- all spectra are recorded and stored as 16k spectra with instant, distortion-free downsizing during or after spectra acquisition.

  Revolutionary Open Digital Pulse Processing.

  Fully user customizable and user configurable DPP.

  Two detector inputs.

  State-of-the-art digital pulse processor with 16-bit ultra-low power ADC with sampling period of 12.5ns.

  Digitally synthesized pulse shapes (triangular, true cusp and others.). Customization of the DPP by synthesizing wide variety of pulse shapes using labZY's original unfolding-synthesis technique.

  Adjustable flat top for all shapes 0 to 2.5 μs.

  Pulse shape rise time from 100ns to 25μs.

  Multiple-pole compensation technique for complete elimination of the pulse tailing.

  Novel incoming count-rate estimator with fast discriminator dead time correction.

  Static and dynamic control of the ADC input offset.

  Automatic thresholds based on statistical noise estimation.

  Built-in and signal-interference free Digital Pulser.

  Two digital inputs - inhibit and coincidence logic.

  Full featured coincidence circuit.

  One slow ADC analog input - can be used for measuring detector temperature or other voltage signals.

  Versatile Trace Viewer (Mixed Signal Oscilloscope).

  Interchangeable interface modules for either wired or wireless connectivity. Supports USB, Ethernet, Bluetooth, low-voltage UART, RS-232, and custom protocols.

  Single mini USB I/O connector for all interfaces.

  Power source 5V/250mA - USB, mini wall adapter, or optional battery (up to 16 hours continuous operation).

  II. DESCRIPTION

  The nanoDPP is the world's first open platform, high-performance Digital Pulse Processor (DPP). Being an open platform, the nanoDPP can easily be incorporated and adapted to specific radiation measurement applications. The DPP algorithms are in-system programmable by uploading FPGA design files. labZY provides standard DPP designs that support a variety of detectors such as HPGE, Silicon drift detectors, LaBr scintillators and other traditional or non-traditional detectors. The nanoDPP has two detector signal inputs A and B. Both inputs accept signals that are user conditioned for digital pulse processing. labZY FPGA designs expect exponential signals. The expected decay time constant of the signals applied to Input A is 6.4μs. Input B may accept exponential signals with time constant from 200ns to 6.4μs. For more information refer to the SPECIFICATIONS and the APPLICATION INFORMATION sections of this data sheet. User signal conditioning circuits should provide amplification, differentiation,pole-zero cancelation and other analog functions required to process signals from detector preamplifiers.
