Software

Calibrating the NI PXIe-4322

 

requires the installation of NI-DAQmx 9.7 or later

 

on the 

calibration system. You can download NI-DAQmx from 

ni.com/downloads

. NI-DAQmx 

supports LabVIEW, LabWindows

/CVI

, C/C++, C#, and Visual Basic .NET. When you install 

NI-DAQmx, you only need to install support for the ADE that you intend to use.
