Removing and Replacing the A51 Solid State Drive (SSD)
Certain unique files exist on the solid state drive (SSD) that are necessary for
proper operation of your analyzer. These files must be copied to another
location to allow them to be installed onto the new SSD after it has been
installed.
If you are replacing the SSD, the following procedure must be performed first.
Copy Unique Files from the Solid State Drive
If installing an SSD for Windows XP: if the user has loaded unique calibration
kit information, navigate to C:\Program Files\Keysight\Network
Analyzer and copy USER_CALKITFILE to a USB flash memory drive. Also copy
any personal user files that you wish to preserve.
If installing an SSD for Windows 7: for more information on the N8983A SSD,
refer to the Windows 7 Operating System Upgrade Kit Installation Note,
