The moderately priced DXP family of instruments combine computer-controlled
analog and digital noise reduction, efficient pulse pileup inspection
and precision multi-channel analysis to produce very high quality
pulse-height spectra from preamplified solid-state x-ray and gamma-ray
detector signals. With a patented architecture utilizing state
of the art analog and digital electronic devices, the DXP sets
a new standard for x-ray and gamma-ray
spectroscopy:
- Compact replacement for shaping amplifier and MCA, with programmable
peaking times ranging 125ns-80 microseconds, 40dB precision
gain adjustment and 8K, 24-bit deep MCA bins!
- Optimal energy resolution with most x-ray detectors, with
light element support for HPGe
and SiLi detectors
- Maximum throughput up to 700,000 counts/sec per channel with
negligible peak shift, minimal loss of resolution
- User directed data inspection criteria
- 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
- External timing signals allow time-resolved data acquisition
for XAFS and X-ray Mapping applications
- High data transfer rates for scanning applications
The Digital X-ray Processor is a 3rd-generation
proprietary architecture that is available in a growing list of
implemenations, including both ready-to-use instruments, and modular
and semi-custom circuit boards suited to fit within larger instrumentation
systems:
The DXP Saturn
is a single full-featured DXP channel with USB 2.0 interface,
detector bias and preamplifier power supplies in a compact enclosure.
This modules provides everything needed to get the most out of
your single-element detector.
The DXP Saturn-OEM is the internal
version of the Saturn module, available with or without the power
supply.
The DXP-XMAP
is a PXI (Extended CompactPCI) module comprising 4 independent
DXP channels with an improved architecture for time-resolved and
mapping data acquisition modes. Combine modules to build a scalable
multi-element detector instrumentation system. PXI crates and
power supplies are sold separately.
The DXP Mercury-OEM
is a single DXP channel with mapping functions and USB 2.0
interface.
The credit-card-sized
microDXP draws less than half a Watt
allowing for very compact assemblies and extended battery life.
