ABSTRACT:
Methods and apparatus are provided for testing an acoustic device that has multiple transducing elements adapted for conversion between acoustic and electrical signals. An electrical transmission signal is generated. The electrical transmission signal is transmitted to one of a first set of channels through a relay element in accordance with a state of the relay element. The electrical transmission signal is transmitted to one of a second set of channels through a multichannel switch of an adapter in accordance with a state of the multichannel switch. The electrical transmission signal is transmitted to a selected transducing element. An electrical received signal is received from the acoustic device in response to the electrical transmission signal.
