Example: Remote Control over LAN Using the VXI-11 Pro-
tocol

In the following example, the program "Measurement & Automation Explorer"
from National Instruments is used on a Windows operating system to set up a
LAN remote control link and to start a remote control session. The remote control
program "Measurement & Automation Explorer" opens the connection to the
instrument (using VISA functionality) and then sends commands to and receives
device responses from the instrument.

A remote control connection requires a VISA installation but no additional hard-
ware 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

 

SGU's computer name or its IP address.

Proceed as described in 

Chapter 2.3.2.2, "Assigning the IP Address"

on page 22

to determine the relevant address information.

In this example, it is assumed that:

A LAN remote control link between the controller and the R&S

 

SGU is

already set up.
For information on setting up the link, see 

Chapter 2.3.2, "Connecting a

Remote PC via LAN"

on page 20.

A VISA and the "Measurement & Automation Explorer" program are
installed on the remote PC.
For detailed information, refer to section "Remote Control Basics" in the
user manual or to the online help of the "Measurement & Automation
Explorer" program.

To configure the controller

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.
