Apparatus and methods for interfacing acoustic testing apparatus with acoustic probes and systems

A method for testing an acoustic device having a plurality of transducing elements adapted for conversion between acoustic and electrical signals, the method comprising:

• generating an electrical transmission signal;
• transmitting the electrical transmission signal to one of a first plurality of channels through a relay element in accordance with a state of the relay element;
• transmitting the electrical transmission signal from the one of the first plurality of channels to one of a second plurality of channels through a multichannel switch of an adapter in accordance with a state of the multichannel switch;
• transmitting the electrical transmission signal from the one of the second plurality of channels to a selected transducing element;
• and
• receiving an electrical received signal from the acoustic device in response to the electrical transmission signal, wherein the electrical received signal corresponds to an acoustic signal converted from the electrical transmission signal and reflected from a target.
