A new system for bioimpedance spectroscopy is presented, which provides an alternative to commercial impedance analysers. Impedance analysers commonly have a limited number of operational modes and are often not well suited to specific applications. Because of its ability to combine an unlimited number of software processing procedures with the use of additional information channels, the system presented enables electrical impedance to be measured precisely. As it is based on digital storage oscilloscope architecture, hardware design is significantly simplified and specific signal detection algorithms may be incorporated.
