Abstract
A low-noise, high-stability PXI-based data acquisition system is presented. The system is built using a National Instruments PXI chassis interfacing with a host computer. Data acquisition functionality and system control is implemented using PXI modules programmed using National Instruments LabVIEW software. Data is fetched from a memory buffer on the PXI hardware to the host computer where digital phase sensitive demodulation is used to extract the I- and Q-channels. The system design and integration is discussed to provide a complete description of a generic PXI-based data acquisition system that can be used in low-conductivity magnetic induction tomography applications.
