Impedance Analyzers
-
A/D converted input signals undergo discrete Fourier transform (DFT) to calculate complex impedance values and obtain parameters and characteristics specific to the DUT, such as its capacitance, inductance and quality factor. Original NF algorithms are also applied to allow equivalent circuits made up of R, L and C along with the constants for those circuits to be estimated from the complex impedance spectrum obtained by sweeping the frequencies.
