5 Instrument Function
5.1 Overview of Instrument Functions
This chapter explains the functions of the R&S SMBV and the options available in the
setting menus. The associated SCPI command is specified for each parameter (where
applicable).
The description begins with the general instrument settings which do not directly affect
signal generation. The majority of these settings can be accessed by means of front-
panel softkey menus and not by means of function block menus.
One exception is, for example, the signal graphics which are called up in the "Graph-
ics" block.
The signal generation functions are then described, beginning with the RF section func-
tions which affect the RF signal and the analog modulations and which are compiled in
the "RF/A Mod" block of the block diagram.
This is followed by an explanation of all functions which are in the signal flow prior to
being fed into the RF block and which do not affect the internal generation of a baseband
signal - I/Q modulation, noise generation and impairment of the digital signal. These
functions are accessed by means of the function blocks"I/Q Mod "and "AWGN/IMP".
The remaining (and largest) part of the chapter describes the functions used for the inter-
nal generation of the signals in the baseband (these functions are provided in the "Base-
band" block).
The general instrument settings include various functions, such as:
●
Setting a defined basic setup using the PRESET key
see chapter 5.2.2, "Default Instrument Settings - Preset Key", on page 104
●
Switching from remote control to manual control using the LOCAL key
see chapter 5.2.4, "Switching to Manual Control - Local Key", on page 133
●
Configuring the generator and its interfaces in the "Setup" menu - e.g. setting the
GPIB address, starting an adjustment, querying instrument data
see chapter 5.2.3, "General Configuration of Instrument - Setup Key", on page 105
●
Generating a hardcopy of the display using the HCOPY key
see chapter 5.2.5, "Generating a Hard Copy of the Display", on page 133
●
Calling up the online help using the HELP key
see chapter 5.2.7, "Help System - Help Key", on page 137
●
Querying messages using the INFO key
see chapter 5.2.6, "Messages - Info Key", on page 136
●
Loading and storing complete instrument settings in the "File" menu
see chapter 5.2.8, "Storing and Loading Instrument Data - File Key", on page 138
●
Calling up the baseband signal graphics in the "Graphics" function block
see chapter 5.3, "Graphical Display - Graphics", on page 144
