Software

Calibrating the NI PXIe-4304/4305 requires the installation of NI-DAQmx on the calibration 
system. Driver support for calibrating the PXIe-4304/4305 was first available in 
NI-DAQmx 15.1.1. 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.
