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.
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):
Each measurement function and generator function has its own data set. If a different
function is selected, this data set is saved. As a result, the previous settings are availa-
ble again when a different function is selected.
The data set is structured differently for each function. The data sets differ with regard
to the following points:
●
Selection of parameter fields / parameters:
Example: With the RMS measurement, various measurement times are offered;
which is not the case for the FFT analysis.
●
Valid value range of parameters
Example: Other frequencies can be set for intermodulation test signals than for
sine-wave signals.
●
Units used
Example: THD measurements and level measurements are specified in different
units.
The following generally applies: All the settings for the other functions, e.g. filter set-
tings and so on, remain in the background with the function settings and are displayed
in the panel and set in the instrument again the next time this function is called up.
4.7.4 Hiding Parameter Fields
The R&S UPP always attempts to keep the panels as short as possible. For this rea-
son, unneeded fields are hidden.
The following example demonstrates this more clearly: As soon as "Auto Sweep" is
selected in the "Sweep Ctrl" menu item in the "Generator Function" panel, all of the
fields required for configuring the sweep are displayed in the panel (together with the
parameters set for the sweep last performed). If the sweep is deactivated, all of the
Settings in the Panels
