Software

Calibrating the NI PXIe-4340 requires the installation of NI-DAQmx on the calibration system. 
Driver support for calibrating the PXIe-4340 was first available in NI-DAQmx 16.1. For the list 
of devices supported by a specific release, refer to the 

NI-DAQmx Readme

, available on the 

version-specific download page or installation media.

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 application software that you intend to use.
