3. To prevent unintentional return to manual operation, disable the LOCAL key of the
instrument with the &LLO command (see Chapter 6.1.3.4, "LAN Interface Mes-
sages", on page 195).
The instrument switches to "REM-LLO" state.
The automatic transition from local state to remote state by a subsequent remote
command, and the command *GTL are disabled.
To return to manual mode is only possible via remote control.
4. Unlock the LOCAL key with &GTR.
6.2.2 Returning to Manual Operation
Before returning to manual control, command processing must be completed. Other-
wise, the instrument switches back to remote control immediately.
To return to manual operation, perform one of the following:
●
Press the LOCAL key on the front panel.
●
Select "Setup > Remote Control Channels > Local".
●
While using the socket communication, terminate the remote control session.
●
Send the interface command &GTL via the remote control interface.
Use the &GTR to enable the LOCAL key if it is locked.
6.2.3 Examples
This sections provides examples for setting up the remote control connection, and
starting a remote control session.
This section assumes basic knowledge of programming and operation of the controller.
A description of the interface commands can be obtained from the corresponding man-
uals.
6.2.3.1 Remote Control over GPIB
The program example in this section is written in VISUAL BASIC. A condition for pro-
gramming in VISUAL BASIC is that the modules NIGLOBAL (Niglobal.bas) and
VBIB32 (Vbib_32.bas) are added to the projects.
Drivers for instrument, e.g. IVI-COM and LabVIEW drivers, are available in the down-
load area of the product website (http://www.rohde-schwarz.com/en/products/
