14 Software and Network Operation
14.1 Operating System
The R&S RTO contains the Windows XP operating system which has been configured
according to the instrument's features and needs. To ensure that the instrument software
functions properly, certain rules must be adhered to when using the operating system.
Risk of causing instrument unusability
The instrument is equipped with the Windows XP operating system. Additional software
can therefore be installed on the instrument. The use and installation of additional soft-
ware 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 XP have been adapted
to the instrument. Existing instrument software must always be modified using only
update software released by Rohde & Schwarz.
Changes in the system setup are only required if the network configuration does not
comply with the default settings (see chapter 14.4.1.1, "Connecting the Instrument to the
Network", on page 377).
14.1.1 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 R&S instrument, it is also recommended that anti-virus software be installed on
the instrument. While Rohde & Schwarz does NOT recommend running anti-virus soft-
ware in the background ("on- 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 R&S White Paper "Malware Protection" avail-
able at http://www.rohde-schwarz.com/appnote/1EF73.
14.1.2 Service Packs and Updates
Microsoft regularly creates security updates and other patches to protect Windows-
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.
