d) The associated graphical window can be opened using the "Show" button in
the "Display" field. The window appears in the same screen so that the effect of
the following settings can be observed directly.
e) In each FFT window, one or two traces (Trace A and Trace B) can be plotted
on the frequency axis.
In this example, the level measurement results of the FFT analysis are to be
displayed on a graph. For Trace A, the "Source" field is therefore set to "FFT
Level Ch1" (this is already preset in the default setup).
The "Alive" setting means that the results are displayed continuously; the
"Hold" setting "freezes" the traces.
f) The settings for the unit, y
‑
axis scaling and grid are already preset in the
default setup; a result should therefore be visible. If necessary, these settings
must be adjusted.
The settings for the x
‑
axis are also mostly correct for this example; they were
explained in the previous example.
g) In the "Analyzer Function" panel, you can also use the "Show" button to open
the graphical window for Post FFT. However, this displays the window in the
same screen, without opening the associated configuration panel.
