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
You might find the following documents helpful as you perform the calibration procedure:
