Using VXI-11, each operation is blocked until a VXI-11 device handshake
returns. However, using HiSLIP, data is sent to the device using the "fire
and forget" method with immediate return. Thus, a successful return of a
VISA operation such as
viWrite()
does not guarantee that the instru-
ment has finished or started the requested command, but is delivered to the
TCP/IP buffers.

Socket Communication
An alternative way for remote control of the software is to establish a simple net-
work communication using sockets. The socket communication, also referred to
as "Raw Ethernet communication", does not necessarily require a VISA installa-
tion on the remote controller side. It is available by default on all operating sys-
tems.
The simplest way to establish socket communication is to use the built-in telnet
program. The telnet program is part of every operating system and supports a
communication with the software on a command-by-command basis. For more
convenience and to enable automation by means of programs, user-defined sock-
ets can be programmed.
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
FPS use port
number 5025 for this purpose. 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 mea-
suring instruments and test systems that is based on standard Ethernet technol-
ogy. LXI is intended to be the LAN-based successor to GPIB, combining the
advantages of Ethernet 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
FPS without additional installation requirements.
