composed of the specific IP address of the instrument and some network and VISA-
specific keywords.
TCPIP::<host address>[::<LAN device name>][::INSTR]
TCPIP
= designates the network protocol
host address
= designates the IP address or hostname of the instrument
[::LAN device name] = defines the protocol and the instance number of a subinstrument
[::INSTR]
= indicates the instrument resource class (optional)
The
IP address
(host address/computer name) is used by the programs to identify and
control the instrument. It is automatically assigned by the DHCP server the first time
the device is registered in the network. Optionally, you can also assign its
LAN device
name
.
The R&S
LCX indicates the IP address in the
Chapter 10.3.2, "LAN settings"
on page 151 dialog. You can also adjust the IP address manually, see
LAN interface addresses manually"
The following section lists the characteristics of the VISA resource strings for the corre-
sponding interface protocols. The emphasized characters determine the protocol.
For description of the protocols refer to
.
VXI-11
TCPIP::<host address>[::inst0][::INSTR]
[::inst0] = LAN device name, indicates that the VXI-11 protocol is used (optional)
inst0
currently selects the VXI-11 protocol by default and can be omitted.
Example:
TCPIP::192.1.2.3::INSTR
Socket communication
TCPIP::<host address>::<port>::SOCKET
port
= determines the used port number
SOCKET = indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred to as
port number) and of "SOCKET" to complete the resource string.
Basically, instruments from Rohde
&
Schwarz use port number 5025 for socket com-
munication.
Example:
TCPIP::192.1.2.3::5025::SOCKET
