1. A method for testing a multiplexing acoustic probe having a plurality of transducing elements adapted for conversion between acoustic and electrical signals and a switch matrix adapted for mapping a plurality of switch-matrix channels to the plurality of transducing elements, wherein the plurality of switch-matrix channels is smaller in number than the plurality of transducing elements, the method comprising:

  • communicating an instruction for the switch matrix to adopt a specified state;

    generating an electrical transmission signal;

    transmitting the electrical transmission signal to one of a plurality of adapter channels through a relay element in accordance with a state of the relay element;

    transmitting the electrical transmission signal from the one of the plurality of adapter channels to one of the plurality of switch-matrix channels;

    transmitting the electrical transmission signal from the one of the plurality of switch-matrix channels to a selected transducing element; and

    receiving an electrical received signal from the multiplexing acoustic in response to the electrical transmission signal.
