DSPEC LF Digital Signal Processing Gamma Ray Spectrometer

DSPEC LF Digital Signal Processing (DSP) based Gamm Ray Spectrometer for Germanium (HPGe) Radiation Detectors
  • Full-featured, digital spectrometer for HPGe and NaI detectors
  • Automatic optimization for best detector performance (patented)
  • ORTEC SMART-1™ intelligent HPGe support
  • Continuous display of detector status and state-of-health information
  • Fast data transfer for live spectrum display
  • Easy installation with true plug-and-play on USB 2.0
  • Excellent temperature and count rate stability
  • MAESTRO MCA Emulation Software included
  • Full computer control of every function

DSPEC LF is a member of the DSPEC USB family of digital technology gamma-ray spectrometers from ORTEC. It provides the same rock solid spectral stability with variation in temperature and count rate and retains many of the valuable attributes of the other two models. Many environmental and radiochemistry laboratories will find this instrument to be the best MCA for day-to-day sample counting with laboratory HPGe or NaI detector systems.

    Detector Interface Module (DIM) (SMART-1) (SMART-INTERFACE)SMART-1™ Support for Quality Data — all the time, every time
    ORTEC's unique SMART-1 detectors are indeed smart. They monitor and store the detector state-of-health (detector temperature, preamp power, bias over range, bias on/off state). A single check by the DSPEC LF will verify the detector is ready and remains ready to perform acquisition. During acquisition, the SMART-1 detector continually monitors the state-of-health (SOH) to ensure the integrity of the acquired data. At the end of acquisition a quick check of the SOH flag in the SMART-1 detector shows if any parameters deviated from specification during the measurement. This is vitally important for environmental samples that must be counted for long periods of time and regulatory-driven samples where data integrity is important.

    Another big advantage is the SMART-1 detectors have the recommended bias value preset at the factory. You no longer have to look through paperwork or for tags on the detector to find the right bias setting. Simply turn on the DSPEC LF and the SMART-1 detector automatically senses the detector temperature, determines the right high voltage bias, and turns it on.

    Fast PC Interface
    The DSPEC LF gives you high speed control over standard USB. The plug-and-play feature makes installation simple. A nearly unlimited number of DSPEC LFs can be connected simultaneously using USB hubs. As an ORTEC CONNECTIONS compatible instrument, the DSPEC LF works in a networked and in a stand-alone configuration. ORTEC CONNECTIONS means: any hardware, any software, anywhere in the laboratory with full seamless control and built-in security.

    Simple, Single-Cable Connection to Detectors
    The DSPEC LF uses the unique ORTEC DIM (Detector Interface Module) to connect the DSPEC LF and the detector with only a single cable. The DIM provides for bias close to the detector so that only signal and low voltage power are carried in the cable. No longer is high voltage bias and the dangers associated with it carried over long distances.

    Monitor Vital Values
    The DSPEC LF shows the values you need on the front panel LCD display. The DSPEC LF displays the instrument ID, name, serial number, preset count conditions, current live and real time, dead time percentage, input count rate, HV status and value, and the serial number for SMART-1 detectors.

    Small Size
    Smaller than a sheet of paper, the DSPEC LF sits right on the desktop. Lightweight and rugged, multiple DSPEC LFs can be stacked on top of one another via their interlocking cases without fear of sliding or tipping. 

    Mix-and-Match with Your Existing MCBs
    ORTEC CONNECTIONS software supports any combination and number of USB devices connected to any computer. For example, two digiDARTs may be combined with two DSPEC LFs connected to the same PC using a USB hub. And any number of other ORTEC MCBs can be connected to the same system by network, printer port, RS-232, or Dual Port Memory.
