4.7 Operating system
The R&S QAR50 contains a Microsoft Windows 10 operating system which has been
configured according to the R&S QAR50's features and needs. Changes in the system
setup are only required when you install peripherals like a keyboard or if the network
configuration does not comply with the default settings.
The drivers and software installed on the R&S QAR50 are adapted to the R&S QAR50.
Only install software updates released by Rohde & Schwarz.
Service packs and updates
Microsoft regularly creates security updates and other patches to protect Windows-
based operating systems. They are released through the Microsoft Update website and
associated update server. Update instruments using Windows regularly, especially
instruments that connect to a network.
Firewall settings
A firewall protects an instrument by preventing unauthorized users from gaining access
to it through a network. Rohde
& Schwarz highly recommends using the firewall on
your instrument. Rohde & Schwarz instruments are shipped with the Windows firewall
enabled. All ports and connections for remote control are enabled.
Note that changing firewall settings requires administrator rights.
Virus protection
Take appropriate steps to protect your instruments from infection. Use strong firewall
settings and scan any removable storage device used with a Rohde
& Schwarz instru-
ment regularly. It is also recommended that you install anti-virus software on the instru-
ment. Rohde
& Schwarz does NOT recommend running anti-virus software in the
background ("on-access" mode) on Windows-based instruments, due to potentially
degrading instrument performance. However, Rohde
& Schwarz does recommend run-
ning it during non-critical hours.
