microDXP

The microDXP is a complete, low power compact digital spectroscopy card design for a wide range of handheld, benchtop and other embedded applications, lowering cost and speeding time-to-market. Its small size allows for very compact assemblies and its low power consumption assures thermal stability and extended battery life.

SKU: MICRODXP Categories: ,

In common with all XIA digital pulse processors, the microDXP replaces the amplifier and MCA functions in conventional spectroscopy systems. The standard digitization rate is 40 MSPS, with an option for 80 MSPS for faster timing applications. The firmware for the FPGA and DSP is stored in a pre-loaded non-volatile flash memory. A PIC processor handles communications, boot-up, dedicated acquisition routines, and power management. In addition to serial I/O, auxiliary digital I/O are available to control external instrumentation, including the capability for I2C. XIA would be pleased to discuss developing custom DSP control code on an NRE basis.

The Development Kit includes the hardware and software necessary to get started with the microDXP, and provides a motherboard (the microCOMU) for filtered power, communication and easy access to I/O lines. All customers must purchase a development kit with their first microDXP order.

  • Credit-card sized unit replaces shaping amplifier, pileup inspector and multi-channel analyzer.
  • Very high throughput: Up to 1 Mcps output count rate with random pulses.
  • User settable gain and pileup inspection criteria.
  • Peaking times from 100 ns – 24 us (with standard 40 MSPS ADC).
  • High level integration of control and acquisition parameters into reconfigurable sets that are stored in non-volatile memory. Stored sets are accessible with a single command to easily switch between corresponding data acquisition modes.
  • Accurate ICR and live-time reporting for precise dead-time corrections.
  • Real multi-channel analysis, allowing for optimal use of data to separate fluorescence signal from backgrounds
  • High-Speed USB 2.0 or serial RS-232 communications
  • Alternate IDMA parallel interface supports a wide range of communications including Universal Serial Bus (USB).
  • Real-time control via 4 general purpose digital I/O lines, two of which can be configured for industry standard I2C interface.
