Overall Impedance Measurement Theory
The simplified model of the 8230 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
