1.3 Operating Principle
1.3.1 Operating Principle
The
ZA57630
applies a sine wave signal from an internal measurement signal source to the
device under test (DUT). It then detects current I flowing through the DUT and voltage V
applied to the DUT, performs discrete Fourier transform (DFT), and calculates impedance Z
(= V/I) of each analysis frequency component from the obtained Fourier coefficient obtained
through the DFT. Parameters such as inductance L, capacitance C, and resistance R are
calculated from the impedance (magnitude and phase angle).
