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.
