Abstract: An organic and inorganic material test system includes at least one test container, a first and second set of electrodes embedded in the at least one test container, a set of transmit circuits coupled to the first set of electrodes, and a set of differential drive-sense circuits (DDSCs) coupled to the second set of electrodes. A first transmit circuit coupled to a first electrode is operable to produce a first transmit signal at a first frequency for transmission through contents of a first test container. A first DDSC coupled to a second electrode of the first test container includes a pair of drive-sense circuits (DSCs) and an output operational amplifier. The pair of DSCs are operable to generate receive signals at the first frequency. The output operational amplifier compares receive signals to produce a signal representative of the contents with respect to positioning of the first and second electrodes.

Abstract: A method includes selecting, by a processing module, a drive-sense circuit to be a transmit drive-sense circuit at different times. At each time of the different times, the method further includes providing, by the processing module, a reference signal having a first frequency to the selected transmit drive-sense circuit, transmitting, by the selected transmit drive-sense circuit, an electrode signal to a corresponding selected test container electrode of a test container of a test container array of a test system and generating, by other drive-sense circuits, a set of sensed signals. The test container contains a content. The method further includes interpreting a plurality of sets of sensed signals as a plurality of impedance values and generating an impedance map based on the plurality of impedance values and with respect to positioning of the set of test container electrodes. The impedance map is representative of electrical characteristics of the content.
