Appendix
Appendix1 Measurement Parameters and Calculation Formula
A1
In general, impedance
Z
is used to evaluate the characteristics of, for example, circuit components.
Measure voltage and current vectors for circuit components relative to AC measurement frequency sig-
nals. The instrument uses these values to obtain the impedance
Z
and phase difference
. The following
values can be obtained from impedance
Z
by rotating the impedance
Z
around the complex plane.
Furthermore, admittance
Y
that is the reciprocal of impedance
Z
can also be used depending on the
characteristics of circuit components. As in the case
of impedance
Z
, the following values can also be obtained from admittance
Y
by rotating the admittance
Y
around the complex plane.
