Software

Calibrating the PXIe-4309 requires the installation of NI-DAQmx on the calibration system.
Driver support for calibrating the PXIe-4309 was first available in NI-DAQmx 17.1. 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.
No other software is required to verify the operation of the TB-4309 (ST), TB-4309 (MT), or
CAL-4309.
