languages such as C#. LabVIEW integrates with CompactDAQ chassis controller hardware to connect to physical sensor or signal data sources. LabVIEW can also connect to oscilloscopes and USB DAQ systems using the ''Measurement and Automation eXplorer'' (MAX) LabVIEW component. In LabVIEW, virtual instruments can be configured and simulated, in order to test data processing when physical hardware is not available. The ''Virtual Instrument Software Architecture'' (VISA) is the back-end component that manages communication between LabVIEW and CompactDAQ hardware. NI SignalExpress LE is provided with every chassis controller for basic data logging and analysis. NI SignalExpress is a
