4 - INTERNAL FUNCTIONAL DIAGRAM

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.

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 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.
