The first diagram shows us the unit set for impedance measurements (in Internal
Mode referring to CLIOwin software, see chapter 13 of the User's Manual); in this
situation the power amplifier and inputs are disconnected while the speaker load is
presented in parallel with CLIO's input and output; this method of impedance
measurement relies on the precise knowledge of the analyzer's output impedance and
stimulates the D.U.T with signals of small amplitude.

Internal connections for impedance measurements (Internal Mode)
The second diagram shows us the unit set for frequency response measurements;
in this situation CLIO's output is fed to the power amplifier that drives the speaker under
test while one among four inputs is directed to CLIO's input.
Input 1
Input 2
Input 3
Input 4
NOTE: when the unit is set for frequency response measurements it is possible to
measure the current flowing in the D.U.T. through the ISENSE output; this permits
impedance measurements stimulating the D.U.T. with signals of variable amplitude up
to the amplifier's maximum power or voltage. Refer to chapter 13 of the CLIOwin User's
Manual.
