Abstract
The hardware and software for a dynamic electrochemical impedance spectroscopy system are described. The applied waveform is a continuous computer-generated multisine waveform added to a potential sweep. A fast potentiostat applies the potential signal and the impedance is derived from the Fourier transforms of the measured current and potential responses. Impedance spectra are available continuously around the cyclic voltammogram. The quality and limitations of the system are investigated with several dummy cells
