NI Virtual Accuracy Laboratory

The NI Virtual Accuracy Laboratory demonstrates the measurement accuracy difference achieved by amplifying and filtering a sensor measurement. This laboratory includes a SCXI-based thermocouple data acquisition system acquiring live data at National Instruments headquarters in Austin, TX. The image in the lower-left corner is a live video feed from the system, acquired using National instruments IMAQ hardware.

You can control the LabVIEW remote panel to heat or cool the measurement chamber and to turn on a motor to generate electrical noise. As you control the LabVIEW VI, notice the difference that filtering and amplification make on the accuracy of your measurement.
