ZEUS:
DPP Digital Pulse Processor.

ZEUS is a digital pulse processor for high rate and throughput applications.

Technical specifications

Input:

• Input signal: Pulsed reset (positive or negative polarity) or continuous reset charge preamplifier typical outputs.
• Dynamic: selectable by jumper (typ: +/- 5V).
• Coarse gain selectable from x0.5 to x1000. Fine gain tuning available for each coarse setting.
• Input impedance: high or 50 Ohm.
• Connectors: signals for inhibiting the acquisition during the reset of preamplifier. Logical inputs for elemental mapping synchronization.
• Maximum input rate: 2 Mcps.

Output

• Output info: Input Count Rate, Output Count rate, dead time, live time.
• Output signals: Real time trigger.
• Spectrum: Up to 16384 (16K) channels.
• Performance:
  
  • ICR 1 Mcps: dead time 10%.
  • ICR 2 Mcps: dead time 30%.

Filtering

• Peaking times: software-selectable from 100ns to 60µs.
• Flat top: software-selectable from 50ns to 30µs.
• Optimal Filtering: optional module for calculating optimal filter on the basis of environmental conditions.
• Automatic Adaptive Filtering Mode: the system automatically selects the best filter in real time during the measurement.

General

• Pileup rejection system: with or without recovery of pile-upped events.
• Diagnostic info: ADC trace, baseline distribution, baseline history.
• Oscilloscope functionality: the system reconstructs the analog waveforms at the output of preamplifier, pre-filtering and complete filtering on PC.
• Others: Dead time correction, channel number selectable from 256 to 16.384, 16 ROIs selectable for fast data acquisition (SCA functionality, TTL output) or 16 digital auxiliary lines.
• USB 2.0 High speed connection to host PC.
