In case the R&S DigIConf and the controller are installed on the same PC, the IP address
127.0.0.1
or
Local Host
is used. Hence the valid visa resource string is:
TCPIP::127.0.0.1::INSTR
Identifying instruments in a network
If several instruments are connected in a network, each instrument has its own IP address
and associated resource string. The controller identifies these instruments by means of
the resource string.
Socket communication
An alternative way for remote control of the software is to establish a simple network
communication using sockets. The socket communication, also referred as “Raw Ether-
net communication” or "Raw socket", does not require a VISA installation on the remote
controller side. Connection can also be performed with "Win Socket" communication.
An alternative way to establish a socket communication is to use a build-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 better utilization and to enable auto-
mation by means of programs, user defined sockets 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. R&S DigIConf uses port number 5026 for this purpose
by default, but can be set. The port is configured for communication on a command-to-
command basis and for remote control from a program.
8.1.3 Starting a Remote Control Session
The instrument and the controller have to be connected with the suitable cable and
switched on.
A remote control program must open a connection to R&S DigIConf (using Raw socket
or VISA functionality), before it can send commands to and receive device responses
from R&S DigIConf.
Refer to
, on page 216 for practical examples on setting up of
a remote control link and starting of a remote control session.
8.1.4 Switching to Remote Control
When it is started, the software is always in the manual operating state and can be oper-
ated via the block diagram.
Starting remote control
Send a command from a controller to the signal generation software.
