Software and Firmware
Calibrating the NI VirtualBench requires the installation of NI VirtualBench application
development support and NI LabVIEW 2013 or later on the Windows calibration system. You
can download the software and driver from
ni.com/downloads.
Table 1 lists the earliest required firmware support for VirtualBench calibration. You can update
the firmware through the VirtualBench application.
