Text Based ADEs
You can use text based ADEs such as LabWindows/CVI, Measurement
Studio, Visual Basic 6, .NET, and C# to create code for using the
SCXI-1102/B/C.
LabWindows/CVI
LabWindows/CVI works with the
DAQ Assistant

code for an voltage measurement task. You can then use the appropriate
function call to modify the task. To create a configurable channel or task in
LabWindows/CVI, complete the following steps:
1.
Launch LabWindows/CVI.
2.
Open a new or existing project.
