The facility has four National Instrument-based data acquisition systems. DAQ boxes one through three each have 104 high speed [dynamic] data acquisition channels, and DAQ box four has 80 channels, making a total of 392 channels available for use in static or shake table testing.
Each of the DAQ boxes is composed of:
- A PC running LabVIEW Real-Time OS with software designed and written by Dr. Patrick Laplace
- National Instruments SCXI 1001 chassis. View SCXI-1001manufacturer information (PDF).
- National Instruments SCXI 1520 signal conditioner modules. View SCXI-1520 manufacturer information (PDF).
- National Instruments SCXI 1314T (TEDS) terminal blocks. View SCXI-1314T manufacturer information (PDF).
Depending on the experiment demands the DAQs may be used individually or in any combination of the four. All systems utilize the IEEE 1451.4 (TEDS) standard to make the system plug and play. This gives us the ability to rapidly setup, change, or troubleshoot instruments while at the same time virtually eliminating any chance of mistakes, such as an incorrect calibration factor.
