The simplest way to establish socket communication is to use the built-in telnet pro-
gram. The telnet program is part of every operating system and supports a communi-
cation with the software on a command-by-command basis. For more convenience and
to enable automation by means of programs, user-defined sockets can be program-
med.
Socket connections are established on a specially defined port. The socket address is
a combination of the IP address or the host name of the instrument and the number of
the port configured for remote-control. All R&S FSW use port number 5025 for this pur-
pose. The port is configured for communication on a command-to-command basis and
for remote control from a program.
LXI Web Browser Interface
LAN eXtensions for Instrumentation (LXI) is an instrumentation platform for measuring
instruments and test systems that is based on standard Ethernet technology. LXI is
intended to be the LAN-based successor to GPIB, combining the advantages of Ether-
net with the simplicity and familiarity of GPIB. The LXI browser interface allows for
easy configuration of the LAN and remote control of the R&S FSW without additional
installation requirements.
The instrument's LXI web browser interface works correctly with all W3C compliant
browsers.
Via the LXI browser interface to the R&S FSW you can control the instrument remotely
from another PC. Manual instrument controls are available via the front panel simula-
tion. File upload and download between the instrument and the remote PC is also
available. Using this feature, several users can access and operate the R&S FSW
simultaneously. This is useful for troubleshooting or training purposes.
For details, see Chapter 13.6.1.4, "How to Configure the LAN Using the LXI Web
Browser Interface", on page 801 and Chapter 13.6.5, "How to Control the R&S FSW
via the Web Browser Interface", on page 807.
If you do not want other users in the LAN to be able to access and operate the
R&S FSW you can deactivate this function.
See Chapter 13.6.6, "How to Deactivate the Web Browser Interface", on page 808.
