Risk of network errors
Connection errors can affect the entire network. If your network does not support DHCP,
or if you choose to disable dynamic TCP/IP configuration, you must assign valid address
information before connecting the instrument to the LAN. Contact your network admin-
istrator to obtain a valid IP address.
Assigning the IP address on the instrument
1. Press the SETUP key and select the "System" tab.
2. Select "Network".
3. Touch and hold (or right-click) "Local Area Connection" and select "Properties" from
the context-sensitive menu.
4. On the "General" tab, select "Internet Protocol (TCP/IP)" and then select "Proper-
ties".
5. Select "Use the following IP address" and enter the address information as obtained
from the network administrator.
6. If necessary, select "Use the following DNS server addresses" and enter your own
DNS addresses.
14.4.1.3 Using computer names
Alternatively to the IP address, each PC or instrument connected in a LAN can be
accessed via an unambiguous computer name. Each instrument is delivered with an
assigned computer name, but this name can be changed.
To change the computer name
1. Press the SETUP key and select the "System" tab or "LXI" tab.
The current computer name is displayed and can be edited.
2. Alternatively, tap "System" on the "System" tab.
3. Select "Change", enter the new computer name and confirm the entry.
14.4.1.4 Changing the Windows 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. R&S instruments are shipped with the Windows firewall enabled and
preconfigured in such a way that all ports and connections for remote control are enabled.
For more details on firewall configuration see the R&S White Paper "Malware Protection"
(available at http://www2.rohde-schwarz.com/file_13784/1EF73_0E.pdf) and the Win-
dows XP help system.
