3 Getting Started
This section helps you to get familiar with the R&S SMBV and provides an introduction
to the general concept of the instrument with a sample of the possible application fields
as well as a description of the main blocks in the signal generation flow.
This section also explains the operating concept in general and includes a brief intro-
duction to operation by a step-by-step description of the configuration. The example is
intended to provide a quick overview of the settings provided. No additional equipment
is required.
3.1 Brief Introduction to the Instrument's Concept
The R&S SMBV provides an entirely digital baseband section for generating I/Q signals
and an RF section with I/Q modulator. The instrument uses I/Q (vector) modulation. Dig-
ital data streams are converted to an I/Q baseband signal. The baseband signal is then
D/A-converted and modulated onto the target RF carrier frequency with the aid of an I/Q
modulator.
For a detailed description of the blocks in the baseband and RF sections, refer to
​
chap-
ter 3.2, "Baseband Section" , on page 52 and
​
chapter 3.3, "RF Section" , on page 54
respectively.
The operating concept of the R&S SMBV employs the following three ways of instru-
ment control:
●
Manual operation
●
Remote control
●
Remote access
Manual Operation
The R&S SMBV can be entirely operated from the front panel. Peripherals such as mouse
or keyboard can be connected but are not essential.
The R&S SMBV is equipped with an intuitive user interface. The central element of the
display is the block diagram that shows the signal flow and processing from the left on
the display to most right, i.e. the generated signal can be seen at a glance.
Each block represents a functional unit of the instrument. Thus the user always knows
the position at which a parameter has an effect in the signal flow. The main settings of a
block are indicated in the block. The interconnection of employed inputs and outputs is
also shown. The user is thus always informed about the connection of inputs and outputs
in the signal flow and where they can be configured. A window is opened for each menu
where parameters can be set. When the window is opened, an entry is made in the
"Winbar" below the display. All open menus are of equal priority (not modal) and can be
accessed any time.
The block diagram in the figure below shows a fully equipped instrument.
