Measurement of Impedance with Computer Controlled Setup

Abstract

Setup for impedance measurement based on AD5933 chip was accomplished and tested with measurement of control samples and AC electroluminescent structures. It was found that the time of the measurement is not limited by MCLK but depends on the period of the excitation frequency, which is processed in the digital modules of AD5933. The measurement performed is in a good agreement with data taken from control impedance analyzer.
