General Specifications

Universal Spectral Engine^® Developed and manufactured by 4pi, the "back-end" electronics of all systems is a stand-alone unit with a small footprint (8.5" x 16.5" x 19"). The unit contains a digital pulse processor, digital image acquisition and scan-control hardware, and Ethernet interface. The Universal Spectral Engine interfaces to any Windows or Macintosh computer that has an Ethernet port.

• Gain stability with temperature: 120 ppm/°C or better
• Peaking time: 0.25 - 80 microseconds (Triangular/Trapezoidal shaping)
• Integral Non-linearity: 0.1% or better of full scale output
• Pileup Inspection: pulse-pair resolution typically better than 250 ns
• HV supply: 0-1000V DC negative
• Operation Temperature Range: +5°C to +40°C; LN2-protect circuitry
• Seamlessly Interfaces to all modern x-ray detectors including resistive feedback
• Simultaneously collect digital, x-ray and WDS images for installations that include WDS
