6.2.3.2 Remote Control 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 SMJ. 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 either the
R&S
SMJ's hostname or IP address. See also Chapter 6.1.3, "LAN Interface" ,
on page 441.
In this example, it is assumed that:
●
A LAN remote control link between the controller and the R&S SMJ is already set
up.
●
The R&S VISA program is installed on the remote PC, see " http://www.rohde-
schwarz.com/rsvisa > RS VISA Release Notes".
Configuring the controller
To remote control the R&S SMJ, we use the R&S VISA Tester application.
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.
To enable the external controller to communicate with the R&S SMJ via TCP/IP proto-
col, set up a remote control link as follows:
1. Make sure that the controller and the instrument are connected in the network (net-
work cable) and switched on.
2. On the controller, start "R&S VISA > Tester 32bit" or "R&S VISA > Tester 64bit",
respectively.
