Software
Calibrating the PXIe-5665 requires you to install the following software on the calibration
system:
•
NI-RFSA 2.5 or later
•
NI Spectral Measurements Toolkit 2.5 or later
You can download all required software from
ni.com/downloads
.
The software supports programming the calibration procedures in the LabVIEW, C, and
LabWindows
™
/CVI
™
application development environments (ADEs). When you install the
software, you need to install support only for the ADE that you intend to use.
Documentation
