Panels are opened using the menu bar (see
chapter 4.5.1, "Opening, Operating, Hid-

described earlier, see

4.7.2 Changing the Instrument
Depending on the installed options, the audio analyzer can be used at analog and digi-
tal interfaces. Optional plug-ins can be installed to allow additional interfaces to be
operated. Each of these interfaces determines the basic characteristics of the instru-
ment, whereby these characteristics are separate for generator and analyzer. These
interface characteristics define quasi-independent instruments within the R&S
UPV.
The settings for these instruments are made in the selection field in the first field of the
"Generator Config" and "Analyzer Config" panel.
Each of these instruments has its own data set. If a different instrument is selected,
this data set is saved. As a result, the previous settings are available when the original
instrument is selected again.
The data set is structured differently for each instrument. The data sets differ with
regard to the following points:
●
Selection of parameter fields / parameters:
Example: In the case of analog instruments, all settings for configuring the analog
interfaces are available (e.g. coupling); all settings for the other instruments, e.g.
the digital sampling rate and so on, do not appear in the panel but remain in the
background.
●
Valid value range of parameters
The frequency ranges in the different instruments may be different.
●
Units used
Levels are output in different units in analog and digital applications.
●
Selection of functions
A number of measurement functions are only available for digital audio applica-
tions; they are therefore not offered in analog instruments; examples: Digital proto-
col analysis, jitter, etc.
The examples given above show that the choice of instrument not only affects the
"Generator
Config" and "Analyzer
Config" panel, but also has an effect on the other
panels.
4.7.3 Changing Functions
The principles that apply to changing an instrument also apply to changing functions
(e.g. from an RMS measurement to a THD measurement or from generating a sine-
wave to multi-tone signal):
