Abstract
A test system includes a test container array including a plurality of test containers, and a plurality of electrodes integrated into the test container array. The test system further includes a plurality of drive-sense circuits coupled to the plurality of electrodes. When enabled, and when the test container contains a content, the set of drive-sense circuits transmit a set of electrode signals on the set of electrodes and generate a set of sensed signals. The test system further includes a processing module that includes a bandpass filter circuit operable to convert a sensed signal of the set of sensed signals to a filtered signal of a set of filtered signals and a frequency interpreter operable to convert the set of filtered signals into a set of impedance values, where the set of impedance values are representative of electrical characteristics of the content.
