2.4 System Overview
This section helps you to get familiar with the R&S SMW. It provides an introduction to
the general concept of the instrument with a sample of the possible application fields.
This section also introduces the main blocks in the signal generation flow.
For information on how to access functions and interact with the R&S SMW, refer to
Chapter 2.5, "Instrument Control", on page 106.
2.4.1 Brief Introduction to the Instrument's Concept
The R&S SMW combines up to two independent signal generators in one instrument
and offers unrivaled RF and baseband characteristics. Due to its modular design, the
instrument can be optimally adapted to the requirements of different applications. Both
RF paths can be equipped with one of the available frequency options with different
upper frequency limit. The baseband section of the R&S SMW is fully digital. It con-
tains the hardware for generating and processing I/Q signals in realtime or generating
signals with an arbitrary waveform generator.
2.4.1.1 Possible Ways to Operate the Instrument
There are three ways to operate the R&S SMW:
●
Manual operation:
Use the touchscreen, hard keys and rotary knob, or an optional mouse and/or key-
board. The principles of manual operation are explained in Chapter 2.5, "Instru-
ment Control", on page 106.
●
Remote control:
Create programs to automatize repeating settings, tests and measurements. The
instrument is connected to a computer running the program.
This way of operation is described in Chapter 12, "Network Operation and Remote
Control", on page 702.
●
Remote operation from a computer:
Remote monitoring and control of the instrument from a connected computer is
based on the common cross-platform technology VNC (Virtual Network Comput-
ing). On the remote computer, any standard web browser (supporting Java) or a
dedicated VNC client (like Ultr@VNC) can be used. See also Chapter 2.5.8,
"Remote Operation over VNC", on page 121.
2.4.1.2 The Signal Flow at a Glance
The R&S SMW is equipped with a large touchscreen, that displays a block diagram.
The block diagram represents the signal flow and the general stages the signal gener-
ation goes through. Depending on the options the R&S SMW is equipped with, the
appearance of the block diagram changes.
