Abstract
A method of impedance measurement of a device under test (DUT) is disclosed based on a random excitation signal, the method comprising the steps of generating the random excitation signal, applying the generated random excitation signal to the DUT through two points of a data acquisition board (DAQ) and re-structuring the converted random excitation signal through a plurality of iterative calibration loops, wherein spectral phase of the random excitation signal is derived from a discrete uniform distribution and its time domain amplitude is controllable. The random excitation signal is a structured Gaussian White Noise (GWN) signal or sequence, which is generated based on the user-defined input parameters such as white noise power level, frequency range between the minimum and maximum frequencies (Fand F), and frequency step (F).
