This paper presents an architectural study and first implementation of a measurement system for impedance spectroscopy. Impedance spectroscopy has shown an increasing potential in quite heterogeneous tasks, including inspection applications. These require a high throughput, so the goal of this investigation is the potential speed-up by applying multi-tone instead of a sweep of single sine waves measurement. An architecture has been conceived and a first implementation on PCB and desktop equipment level has been achieved. First experiments showed a bandwidth up to 90 MHz of the system.
