R&S ESU

5.3 Getting Started

The short and simple operating sequence provided below enables you to quickly put
the instrument into operation and set its basic functions. As a prerequisite, the GPIB
address, which is factory-set to 20, must remain unchanged.
1. Connect instrument and controller using GPIB cable.
2. Write and start the following program on the controller:
3. To return to manual operation, press the LOCAL key at the front panel.

5.4 Starting Remote Control

On power-on, the instrument is always in the manual operating state ("LOCAL"
state) and can be operated via the front panel.
It is switched to remote control ("REMOTE" state)
GPIB as soon as it receives an addressed command from a controller.
if it is controlled in a network (RSIB interface), as soon as it receives a command
from a controller.
RS-232 as soon as it receives the command "@REM" from a controller.
During remote control, operation via the front panel is disabled. The instrument
remains in the remote state until it is reset to the manual state via the front panel or
via remote control interfaces. Switching from manual operation to remote control
and vice versa does not affect the remaining instrument settings.

Display Contents during Remote Control

During remote control, only the LOCAL softkey appears, with which it is possible to
return to manual operation.
In addition, the display of diagrams and results can be blanked out with the com-
mand "SYSTem:DISPlay:UPDate OFF" (default in remote control) to obtain opti-
mum performance during remote control.
