Biological test system data processing

A test system comprises:

• a test container array including a plurality of test containers;
• a plurality of electrodes integrated into the test container array, wherein a set of electrodes of the plurality of electrodes is integrated into a test container of the test container array;
• a plurality of drive-sense circuits coupled to the plurality of electrodes, wherein a set of drive-sense circuits of the plurality of drive-sense circuits is coupled to the set of electrodes, and wherein, 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, wherein an electrode signal of the set of electrode signals includes a transmit signal component having a unique frequency;
• and
• generate a set of sensed signals, wherein a sensed signal of the set of sensed signals includes a set of unique frequencies, wherein a first unique frequency of the set of unique frequencies corresponds to a first transmit signal component received by a drive-sense circuit of the set of drive-sense circuits from a first other drive-sense circuit of the set of drive-sense circuits;
• and
• a processing module operably coupled to:
• interpret the set of sensed signals as a plurality of impedance values, wherein the set of unique frequencies correspond to a set of impedance values of the plurality of impedance values;
• and
• generate an impedance map based on the plurality of impedance values and with respect to positioning of the set of test container electrodes, wherein the impedance map is representative of electrical characteristics of the content.
