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
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.
