1.2 Impedance Parameters
Due to the different testing signals on the impedance measurement
instrument, there are DC impedance and AC impedance. The
common digital multi-meter can only measure the DC impedance,
but the Model 885 can do both. It is a very important issue to
understand the impedance parameters of the electronic component.
When we analysis the impedance by the impedance measurement
plane (Figure 1.1). It can be visualized by the real element on the
X-axis and the imaginary element on the y-axis. This impedance
measurement plane can also be seen as the polar coordinates. The Z
is the magnitude and the θ is the phase of the impedance.
