4.15.2 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 "Setup" key and select "Network Settings".
The computer name is displayed under "Hostname".
2. Press the "Setup" key, select "Protection" and enable the "Protection Level 1".
The default password is 123456.
The parameter "Hostname" in the "Network Settings" dialog is now enabled for
configuration.
3. Change the "Hostname".
4.16 Remote Access via an External Controller
The R&S SMB can be remote accessed from a remote computer (external controller)
via a network link. This allows convenient operation of the instrument from the desktop
although the instrument is integrated in a rack somewhere else.
For an overview of the instrument's operating concept and the different ways to control
and operate the instrument, see Chapter 7, "System Overview", on page 58.
There are different ways to establish a remote access connection to the signal genera-
tor but all of them require an established LAN connection between the instrument and
the remote computer. The simplest way to remote access the instrument is to use a
