2.6.3 Using computer names
In a LAN that uses a DNS server (Domain Name System server), each PC or instru-
ment connected in the LAN can be accessed via an unambiguous computer name
instead of the IP address. The DNS server translates the host name to the IP address.
This is especially useful when a DHCP server is used, as a new IP address may be
assigned each time the instrument is restarted.
Each instrument is delivered with an assigned computer name, but this name can be
changed.
The default instrument name is a non-case-sensitive string that follows the syntax
rs<instrument><serial number>
.
The serial number can be found on the rear panel of the instrument. It is the third part
of the device ID printed on the bar code sticker:
Querying and changing a computer name
1. Press the "Windows" key to access the operating system.
2. Select "Start > My Computer > Properties > Computer Name".
The computer name is displayed under "Full Computer Name".
3. To change the computer name, select "Change", enter the new computer name
and confirm the entry.
2.6.4 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. 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.
For more details on firewall configuration, see the Rohde & Schwarz White Paper
1DC01: Malware Protection .
Note that changing firewall settings requires administrator rights.
To transfer waveform files generated on an external PC using R&S WinIQSIM2, you
have to disable the firewall.
