New Approaches to High Performance Data Acquisition

Abstract:
Several novel concepts are presented from design of the new Hi-Techniques
Synergy data acquisition system. Traditionally, time-domain and
frequency-domain instruments each required unique front end amplification,
filtering and processing. Recent development in powerful, compact and
inexpensive hardware now allows a single, more versatile instrument.
Selectable analog and digital filtering types can now provide optimal response
for both time domain and frequency domain applications. A high digitizing rate
can offer MHz bandwidth for ballistics and pyroshock
applications while digital filters implemented in hardware provide anti-alias
protection for vibration tests. Voltage, bridge, ICP accelerometer and
thermocouple signal conditioning can be provided on all channels to eliminate
module exchange or external amplifiers. Standard Ethernet communication allows
front panel operation or remote location of the instrumentation up to several
kilometers. Increased DSP capabilities can provide on-the-fly analysis with
custom user programming.
