3.3 Types of Screens
The PNTS present three types of user interface main screens:
„
Plots
„
Tables
„
Input Components
Occasionally it will present a dialog with informational messages, error messages or request that
you take control (as described in
“3.2.3 User in Control” on page 14) when you execute certain
functions.
3.3.1 Plots
Figure 3 on page 11 and Figure 4 on page 12 are examples of plots. Four of the five main screens
are plots. Plots can be configured in various ways described in detail in later chapters dedicated to
data set configuration.
„
The (f) Phase Noise plot also presents data subsets such as the Spur Table and meta
information such as Integrated Phase Noise in tables accessible through its configuration
softkey and mouse menus.
„
The Allan deviation plot can also be viewed in terms of a table.
3.3.2 Tables
There are two types of tables. The first is a read-only table such as the Allan deviation table. The
second type is an interactive table. Both types present softkeys which scroll the table up or down
as can be seen in the example table on the right side of
Figure 4 on page 12. The scroll keys have
different effects depending on the type:
„
Read-only tables scroll the data set one page at a time.
„
Interactive tables select the row following or preceding the currently selected row.
Interactive tables move the selection a row at a time because they allow you to operate on the
selection. An example of this is the (f) phase noise plot’s spur table, which lets you place a
marker at the selected spur’s frequency. See
“Chapter 5, The Spur Table” on page 42 for details.
To perform operations upon a row in an interactive table, use the mouse pointer to select the row,
then right-click the selected row and choose one of the menu items that are generally available.
To vertically scroll up or down a table, use the scroll bar located on the right side of the table, or, if
available, the scroll wheel located on your mouse.
3.3.3 Configuration Screens
The test set can be configured in various ways. Configuring aspects of its function involves setting
parameters. Input components are used to interface with and make these settings. Components for
related parameters are often grouped, as multiple parameters affect a certain function. Examples of
such groups can be found in chapter
“4: Global System Settings” on page 21 and its subsections.
