For an overview of the instrument's operating concept and the different ways to control
and operate the instrument, see chapter 3.1, "Brief Introduction to the Instrument's Con-
cept", on page 65.
There are different ways to establish a remote access connection to the signal generator
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 Web
browser, such as Windows Internet Explorer or Mozilla Firefox for instance. Alternatively
a remote access via a special application can be used. Two free-of-charge programs are
available for setting up the remote access connection: the Windows application Remote
Desktop for PCs with Window operating system and the program Ultr@VNC for PCs with
Linux/Unix or Windows operating system. Using of each of this two applications requires
additional istallation.
See table 2-1 for an overview of the different ways to establish a remote access con-
nection to the signal generator.

When the connection is set up with Remote Desktop, the device firmware of the signal
generator is disabled. Direct control on the instrumenbt is not possible while manual
remote-control is active. The access of an external PC is indicated by the logon screen
of Windows XP Embedded which identifies the accessing user.
When the connection is set up with Ultr@VNC, direct control on the instrument is possible
while remote access is established.
For return to direct operation on the instrument, the connection must be cut. After cutting
the connection, it is still enabled and can be established again any time. The connection
is disabled only after deactivation of the program.
