13.8.3 Establishing a remote control connection over the LXI browser
interface
Via the LXI browser interface to the R&S SMA100B one or more users can control the
instrument remotely from another PC without additional installation. Most instrument
controls are available via the front panel simulation. File upload and download between
the instrument and the remote PC is also available.
Starting a remote control via the LXI web browser
1. On the instrument, enable the LAN interface.
See Chapter 13.7.1, "How to enable access via LAN", on page 415.
2. Connect the remote PC and the instrument in the same network.
See Chapter 13.7.3, "How to connect to LAN", on page 415.
3. On the remote PC, start a web browser that supports HTML5 (W3C compliant).
4. Enter the IP address of the R&S SMA100B in the browser's address bar.
The R&S SMA100B's welcome page is displayed.
5. In the navigation pane, select "Instrument Control" > "Web Control".
Remote access to the instrument requires the password. The default password is
instrument.
6. Enter the password and confirm with the [Enter] key.
After the connection is established, the current screen of the R&S SMA100B is dis-
played in the browser window.
7. Use the mouse cursor and keyboard to access the functionality of the instrument
as you would directly perform on the instruments touchscreen and front panel.
13.8.4 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 SMA100B. R&S VISA is
running 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 SMA100B's
hostname or its IP address.
See also Chapter 13.2.1, "LAN interface", on page 381.
Setting up the controller with R&S VISA
To remote control the R&S SMA100B, we use the R&S VISA Tester application. The
application communicates via TCP/IP protocol.
