a) In the "Analyzer
Function" panel already used for configuring the THD+N mea-
surement, an FFT analysis to be performed following the measurement can be
set after the actual measurement function has been selected.
To do this, activate the "Post
FFT" checkbox.
The size of the FFT can be adjusted if necessary.
b) To graphically display the results of the FFT analysis, first change to screen 5,
which is empty in the default setting.
c) Open the menu bar and from the selection list under the "DispConfig" button,
select the "FFT Graph 1 Config" panel.
As explained in the previous example, the way in which the measurement
results are presented is determined in the
configuration panels
. Each graphi-
cal window has its own configuration panel.
The "FFT Graph 1 Config" panel required here has two columns; to simplify
matters, only Trace A is shown in the example.
