Tested software
The drivers and programs used on the instrument under Microsoft Windows are
adapted to the instrument. Only install update software released by
Rohde & Schwarz to modify existing instrument software.
You can install additional software on the instrument; however, additional soft-
ware can impair instrument function. Thus, run only programs that
Rohde & Schwarz has tested for compatibility with the instrument software.
The following program packages have been tested:
●Symantec Endpoint Security – virus-protection software
●FileShredder - for reliable deletion of files on the hard disk
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.
Firewall settings
A firewall protects an instrument by preventing unauthorized users from gaining
access to it through a network. Rohde & Schwarz highly recommends the use of
the firewall on your instrument. Rohde & Schwarz instruments are shipped with
the Windows firewall enabled and preconfigured in such a way that 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 fire-
wall settings and scan any removable storage device used with a
Rohde & Schwarz instrument regularly. It is also recommended that you install
anti-virus software on the instrument. 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. How-
ever, Rohde & Schwarz does recommend running it during non-critical hours.
