A. IMPEDANCE PARAMETERS
The impedance of the measure instruments can be classified as DC impedance
and AC impedance, according to the measure signals. Generally, in multimeters,
the impedance to electrical measurement is DC; while in the digital bridges can be
used to measure the AC and DC impedance.
The MX-1050 is not only a smart equipment with double display, digital portable
LCR bridge with functions of DC and AC impedance measurement. Impedance is
to where are extracted the fundamental parameters to evaluate electronic elements
and the system of a circuit. Linear crystal diode resistance is defined for the Ohm
Law under conditions of continuous current. The voltage and current proportion is a
complex number, under conditions of alternate current.
An impedance vector includes a real part (Resistance R) and an imaginary part
(reactance X). The impedance is express by R + jX in the rectangular coordinates
system or express by |Z| amplitude and the phase angle (θ) in the polar coordinates
system. The figure 1.1 illustrates the relationship.
