For an introduction into the manual operating of the instrument, detailed operating
instructions and an overview of menus refer to chapter 4, "Manual Operation",
on page 85.
For an indepth description of the dialog boxes and the instrument functions refer to sec-
tion "Instrument Fuctions".
Remote Control
Remote control is an operation of the instrument by means of remote control commands
or programs that automatize repeating settings. The instrument is connected to a com-
puter running the program.
This way of operation and the instructions how to set up a connection for remote control
are described in the chapter 6, "Remote Control Basics", on page 449. The description
of the remote control commands is provided in chapter 7, "Remote Control Com-
mands", on page 489.
Remote Access
Remote access is the operating of the instrument from a remote computer. Both the R&S
SMU and the computer are connected in a LAN.
Remote access in contrast to remote control does not use remote-control commands
but a separate software which is installed on the remote computer. After its start, the
software simulates the user interface of the instrument. The instrument can thus be oper-
ated from the remote computer as on the unit itself. The individual functions are operated
using the mouse and keyboard. Specific instrument functions can be executed using
specific key combinations on the keyboard or a front panel key emulation that can be
operated with the mouse.
This way of operation and the instructions how to set up a connection for remote access
are described in chapter 2.7, "Remote Access via an External Controller", on page 46.
3.2 Applications of the Instrument
The modular design of the R&S SMU allows the instrument to be equipped with two paths.
This allows a multitude of applications to be performed for which several signal genera-
tors were previously required. A few examples are given below.
3.2.1 Generation of digitally modulated signal
The main field of application of the R&S SMU is the generation of digitally modulated
signals. In the instrument, a digitally modulated signal can be generated in several ways.
Internally generated I/Q signal
The I/Q signal is generated internally in the R&S SMU. One or two baseband generators
can be installed. The signals produced by the two generators can be added (possibly with
frequency offset).
