Our 2016 EIA Energy award was presented to a group of people who wanted to supply the data acquisition system for a unique new microseismic instrument (the MDAS).
Microseismic systems use ultrasonic transducers as transmitters and receivers in place of real-world seismic sources and geophones to study seismic phenomena in laboratory scale samples. These studies help us understand critically important processes that occur on global and local scales, from the seismic events related to earthquakes to fluid transfer mechanisms associated with the geosequestration of greenhouse gases.

The team cited high channel density, range of I/O types, precise multiboard timing and synchronisation, and overall data throughput that can be achieved with PXI Express as critical factors in meeting the challenging specification. Additionally, LabVIEW's flexible environment was a major factor in their ability to integrate the high-level hardware drivers, intensive data preprocessing, and communications to external tools as essential to their success.
