1. To Make Effective Use of This Manual
How to use this manual
When writing programs, it is not necessarily required to use all the information in this
manual. Basically, the structure of remote control system that the user decides will
determine required equipment, programming language that is necessary to understand, and
command set to control the E4991A.
Selecting the structure of remote control system
First, select the remote control system to suit the purpose from the following remote
control system structures, and read this manual according to the contents written there.
1. Manual operation
Operating the E4991A through the front panel of the E4991A or keyboard/mouse. This
doesn’t suit the measurement of complex setting combination while it doesn’t require
the preparation of external controller separately or the knowledge of programming to
control the E4991A. Refer to the operation manual for how to operate E4991A through
the front panel or keyboard/mouse.
2. Manual operation using remote user interface function
If remote user interface function is used, it becomes possible to operate the E4991A
from Personal Computer by providing the environment of the E4991A user interface
(keyboard/mouse connected to the E4991A) for the Personal Computer connected to
the E4991A on LAN. Refer to the operation manual for the set-up and usage of remote
user interface function.
3. GPIB remote control system
The E4991A can be controlled from external controller (for example, computers like a
Personal Computer, Work Station, etc.) through GPIB interface. The outline of the
system is explained in
“Outline of GPIB remote control system” on page 26.
4. Remote control using macros in the E4991A
The E4991A and peripheral equipment can be controlled by using the macros (Visual
Basic for Application) which is installed in the E4991A. The outline of the system is
explained in
“Remote control using E4991A macros” on page 32.
5. Remote control using remote user interface function and application software.
The E4991A can be controlled from the Personal Computer that is connected to the
E4991A by the remote user interface function, using application software (Microsoft
Visual Basic, and etc.). The outline of the system is explained in
“Remote control using
remote user interface function and application software” on page 35.
