10.1 Overview of remote access modes
This section outlines the possible access modes and their major characteristics.
Remote control (SCPI)
●
A remote PC controls the instrument, usually using VISA (Virtual Instrument Soft-
ware Architecture) interfaces.
●
Remote control disables the manual operation of the instrument; you can set differ-
ent lock states.
●
The GUI is not visible.
●
Remote control commands (SCPI) perform the settings, either individually or in
sequences (SCPI programs).
●
Using SCPI programs is faster than the manual operation, since they automate
repeating applications.
Remote operation (VNC)
●
A remote device accesses the instrument using the common platform technology
VNC (Virtual Network Computing).
●
The protocol allows simultaneous operation from several remote devices and the
instrument nevertheless remains locally operable.
●
The GUI is visible.
●
To perform the settings, you can operate the instrument as with the manual control.
●
During remote operation over VNC, the direct control of the instrument is not dis-
abled.
You can control the instrument from the front panel and over the remote computer
alternately.
●
Clients supporting remote operation depend on the used remote device, see
Table 10-1.
●
How to: see Chapter 10.6.1.2, "Accessing the R&S LCX over VNC", on page 165.

●
Dedicated client software
Client Software must be installed. Fast, supports several options like
full screen mode or auto-login.
●
Any web browser
Java Runtime must be installed
and activated in the browser set-
tings.
Fast and convenient - only the
instrument address required.
Java runtime is sometimes con-
sidered as security concern.
●
Web browser with HTML5
Web sockets must be supported. Slower than the other modes.
No additional installation or acti-
vation required.
No security concern.
