The DSA-LX® analyzer offers cost effective, no-compromise DSP-quality spectroscopy in a very compact package. It is operated through Genie 2000 spectroscopy software which provides the user with ultimate flexibility.
The DSA-LX analyzer is a full featured 16K channel integrated Multichannel Analyzer based on advanced digital signal processing techniques (DSP). When paired with a computer running Genie 2000 software the DSA-LX unit becomes a complete spectroscopy workstation, capable of the highest quality acquisition and analysis. The instrument interfaces to existing detector technologies such as HPGe, NaI, Si(Li), CdTe or Cd(Zn)Te.
The DSA-LX analyzer offers cost effective, no-compromise DSP-quality spectroscopy in a very compact package. It is operated through the Mirion Genie 2000 spectroscopy software which provides the user with ultimate flexibility. A wide range of application specific software options are available under the Genie 2000 family.
This highly integrated instrument incorporates front end signal conditioning, a fast digitizing analog-to-digital converter (ADC), programmable digital filters, digital oscilloscope, automatic pole/zero and base line restorer, digital fast discriminator, two groups of 16K channel spectral memory, digital stabilizer and a dual-range HVPS – all in a small, compact package. Lighted indicators are included on the front and rear panels to alert the user to power, acquisition, communication, high voltage and count rate status at a glance.
The use of DSP technology improves the overall signal acquisition performance. Signal filtering functions previously implemented in traditional analog electronics are limited. DSP allows filtering functions and pulse shapes that are not realizable using conventional analog processing techniques. The result is a more efficient trapezoidal filter function, which exhibits less processing time, less sensitivity to ballistic deficit, and superior resolution. With trapezoidal filtering, the pulses can be processed more rapidly and accurately, so the spectrum resolution is enhanced while throughput is increased.
The DSA-LX unit offers peak gain stability at up to a factor of two to three times better than past generation analog products while Zero drift is barely measurable over the full operating temperature range of the instrument.
The DSA-LX unit supports both the traditional Pulse Height Analysis (PHA) mode as well as a MultiChannel scaling (MCS) mode for time varying applications. The MCS mode can display data from an external TTL input, a full spectrum integral or a Region of Interest (ROI).
The DSA-LX analyzer provides host communications via Universal Serial Bus (USB) 2.0 interface which provides full speed communications at 12 Mbit/s. USB provides the additional capability of having multiple units attached to a single host/port via a USB hub.
The DSA-LX analyzer includes an interface which allows the user to monitor the system status, view the spectrum, maintain and update system settings and access the built in digital oscilloscope. With the built in digital oscilloscope, the user views a graphical reconstruction of the digitized, filtered signal. Scaling and trigger functions are similar to those of an actual oscilloscope.
