The xMap is a multi-channel digital pulse processor designed for high-rate x-ray spectroscopy and fast-mapping applications at synchrotron beamlines, and offers the following advantages:

  • Compatible with SDD, HPGe and other x-ray detector types
  • Output Count Rates approaching 1 Mcps per channel
  • Sophisticated pile-up inspection
  • 4-channel PXI card easily expandable to 100+ channels
  • Auto gain adjust/calibration across all channels
  • Onboard dual memory for deadtimeless MCA, SCA and List Mode mapping
  • Open source driver libraries for custom DAQ control

Is the xMAP compatible with 64-Bit Windows?

The xMAP itself is fully compatible with 64-bit Windows systems. However, the PXI-PCI and PXI-PCIe bridges may not be supported. We have confirmed that 64-bit Windows supports the following PXI-PCI(e) bridges:

  • PCI-8361

  • PCI-8366

  • PCIe-8361

  • PCIe-8362

  • PCIe-8371

  • PCIe-8375

  • PCIe-8381

  • PCIe-8398

Why can't I execute burst reads of data from the hardware?

The burst read function used in reading out xMAP spectrum and mapping data is particularly sensitive to operating conditions. A problematic PCI bridge could start up normally, but will cause error at spectrum and mapping data readout. The problem may be caused by one or more of the following causes:

  1. a faulty fan in the system causing overheating,
  2. dust on the PCI bridge,
  3. an incompatible PCI/PCIe bridge for your operating system, 
  4. or incorrect drivers.
How do I install the 64-bit PLX Windows Drivers?
  1. Connect and power on the crate and boot up the PC. Check if “Other PCI bridge device” and “PCI devices” show up in Device Manager.
  2. Run “NI Device Drivers CD” from Aug 2011, reboot. Note: starting with a newer version of the Device Drivers CD, NI-VISA, or NI PXI Platform Services should also install the necessary drivers.
  3. If Device Manager shows a problem on a “PCI standard PCI-to-PCI bridge” device (error code 31) or does not show an “Other PCI Bridge Device,” there may be a compatibility problem with the host system BIOS. Follow the steps in the NI MXI-Express BIOS Compatibility software. For example, the combination of Lenovo Thinkpad L512 and PXI-1033 crate connected via NI ExpressCard-8360 requires this update.
  4. Verify NI PXI 8360 and PXI-6221 are recognized after reboot.
  5. Install ProSpect. Reboot as directed.
  6. The xMap drivers should have been installed correctly now, if not, try the following procedures.
  7. In Device Manager open the 2 “Other PCI bridge device”, update drivers, and select the drivers\plx folder in ProSpect’s program directory.
  8. Device Manager should now recognize an XIA xMAP Digital Spectrometer (64-bit) under Other Devices.
