3. Step: Selection of required measurement
a) The basic settings for configuring the analyzer are again made in the "Analyzer
Config" panel.
These settings are made in the same way as shown in the previous example.
b) Next, the "Analyzer
Function" panel is activated.
The measurement function and measurement method are set in this panel.
First, the measurement function is selected by opening the parameter list and
selecting the item THD+N
&
SINAD.
c) In the next field "Meas Mode", various modes for distortion factor measurement
can be selected; the presetting "THD+N" is correct for this example.
The "Dynamic Mode" determines the maximum dynamic range for this mea-
surement: Fast measurement with restricted dynamic range or maximum
dynamic range with a slightly longer measurement time are the two possible
options.
d) With the THD+N measurement, the fundamental of the signal to be measured
is suppressed using a notch filter. The audio analyzer can automatically deter-
mine the fundamental from the spectrum and adjust the notch filter to it ("Fun-
damental Auto").
Filter and Equalizer are only required in exceptional cases.
