13.7.4 Establishing a Remote Control Connection over LAN Using VXI-11
Protocol
In this example, the I/O software library R&S VISA from Rohde & Schwarz is used to
set up a LAN remote control link and remotely control the R&S SMW. R&S VISA is run-
ning on a controller PC with Windows operating system. When the connection is set
up, you can send commands to the instrument and receive the responses.
The remote control connection requires a VISA installation but no additional hardware
on the controller PC. The LAN I/O channel is selected at initialization time using the
VISA resource string (also referred to as "address string"). A VISA alias (short name) is
used to replace the complete resource string. The host address is the R&S SMW's
hostname or its IP address.
See also Chapter 13.2.1, "LAN Interface", on page 776.
Setting up the controller with R&S VISA
To remote control the R&S SMW, we use the R&S VISA Tester application. The appli-
cation communicates via TCP/IP protocol.
The instrument is preconfigured for networks using DHCP (dynamic host configuration
protocol). If this configuration is used, enter the computer name in the position of the IP
address.
1. On the instrument:
a) Enable the LAN interface.
See Chapter 13.6.1, "How To Enable Access via LAN", on page 803.
b) Enable "SCPI over LAN".
See Chapter 13.6.2, "How To Activate LAN Services", on page 803.
2. On the controller (remote PC), install the R&S VISA program.
See http://www.rohde-schwarz.com/rsvisa > "RS VISA Release Notes".
3. Connect the controller and the instrument in the same network (network cable).
Switch them on.
See also Chapter 13.6.3, "How To Connect to LAN", on page 804.
4. On the controller, start "R&S VISA > Tester 32bit" or "R&S VISA > Tester 64bit".
