PNA Series Microwave Network Analyzers
E8361A

Overview

This recovery procedure will completely restore the operating system of the PNA series
network analyzer to the original factory condition. It will not function if the hard drive is
damaged.
If you have made an emergency repair disk, you may be able to recover from some
Windows system problems without the loss of data. Refer to Windows 2000 Help or contact
your systems administrator.
Use this procedure for the following types of situations:
• If you are recovering from a corrupted operating system.
• If you have security concerns where all previous usage remnants need to be eliminated.
• If the network analyzer must be in a known configuration, such as for rental companies.
The hard drive in the PNA series network analyzer has two partitions (drives):
• drive—contains the Windows 2000 operating system (NTFS format). This is the
C:
normally used partition and it contains all the programs and other needed files.
• : drive—is the Disaster Recovery Partition. It contains a compressed image of the C:
D
drive as it existed when shipped from the factory, plus its support files. It may also
contain other items such as drivers or firmware. DO NOT USE THIS DRIVE FOR
NORMAL DAY-TO-DAY USE.
The recovery procedure will erase the entire C: drive and the following
IMPORTANT
information will be lost:
• all changes and additions made to the network analyzer since it's purchase
(except options)
• all user accounts and passwords
• all added programs
• all saved instrument states
• all user configurations and Windows settings
The above listed information can be saved by copying it to a floppy disk or to a folder on the
D: drive; the D: drive will not be affected by the restoration process. In addition, factory
instrument calibration will not be affected if no changes have been made since the original
factory calibration. If changes have been made through the service routines, copy all files
that are prefixed with mxcalfile_ in the C:/Program Files/Agilent/Network Analyzer directory
to the D:/Calfiles directory. Permanent instrument options should not be lost.
