Overall Impedance Measurement Theory

The simplified model of the 6632 impedance measurement, Vs is the test signal
voltage and RO is source resistance. If the current across the DUT is I when a
test signal voltage V is applied, the DUT's impedance, Z, is expressed by Z = .

Impedance, Z, contains real and imaginary parts. The figure shows vector
representation of impedance as follow.

R: Resistance
X: Reactance
|Z|: Impedance
θ: Phase Angle
