2.2 Windows Operating System
The instrument contains the Windows 7 operating system which has been config-
ured according to the instrument's features and needs. Changes in the system
setup are only required when peripherals like keyboard or a printer are installed
or if the network configuration does not comply with the default settings. After the
R&S FSW is started, the operating system boots and the instrument firmware is
started automatically.
To ensure that the instrument software functions properly, certain rules must be
adhered to concerning the operating system.
Risk of causing instrument unusability
The instrument is equipped with the Windows 7 operating system. Addi-
tional software can therefore be installed on the instrument. The use and
installation of additional software may impair instrument function. Thus, run
only programs that Rohde & Schwarz has tested for compatibility with the
instrument software.
The drivers and programs used on the instrument under Windows 7 have
been adapted to the instrument. Existing instrument software must always
be modified using only update software released by Rohde & Schwarz.
The following program packages have been tested:
●R&S Power Viewer Plus - virtual power meter for displaying results of the
Power Sensor R&S NRP-Zxx (install only this component!)
●Symantec Endpoint Security – Virus-protection software
●FileShredder - for reliable deletion of files on the hard disk
2.2.1 Virus Protection
Users must take appropriate steps to protect their instruments from infection.
Beside the use of strong firewall settings and regularly scanning any removable
storage device used with a Rohde & Schwarz instrument, it is also recommended
that anti-virus software be installed on the instrument. While Rohde & Schwarz
does NOT recommend running anti-virus software in the background ("on-
Windows Operating System

Preparing for Use
R&S®FSW
19Getting Started 1312.9420.02 ─ 15
access" mode) on Windows-based instruments, due to potentially degrading
instrument performance, it does recommend running it during non-critical hours.
For details and recommendations, see the Rohde & Schwarz White Paper "Mal-
ware Protection" available at http://www.rohde-schwarz.com/appnote/1EF73.
2.2.2 Service Packs and Updates
Microsoft regularly creates security updates and other patches to protect Win-
dows-based operating systems. These are released through the Microsoft Update
website and associated update server. Instruments using Windows, especially
those that connect to a network, should be updated regularly.
For more details and information on configuring automatic updates see the R&S
White Paper "Malware Protection" (available at http://www.rohde-schwarz.com/
appnote/1EF73).
2.2.3 Login
Windows 7 requires that users identify themselves by entering a user name and
password in a login window. By default, the R&S FSW provides two user
accounts: an administrator account ("Instrument") with unrestricted access to the
computer/domain, and a standard user account ("NormalUser") with limited
access. In both cases the initial password is 894129. Note that this password is
very weak, and it is recommended that you change the password for both users
after initial login. You can change the password in Windows 7 for any user at any
time via "Start > Control Panel > User Accounts".
Secure User Mode
If the secure user mode option (R&S FSW-K33) is installed, an additional
account is provided: the "SecureUser", also with the password 894129.
When the secure user mode is activated the first time after installation, the
user is prompted to change the passwords for all user accounts in order to
improve system security.
For details see chapter 2.7, "Protecting Data Using the Secure User Mode",
on page 31.
For the administrator account, an automatic login function is active by default. If
activated, login is carried out automatically for the administrator (with full access)
