Apparatus and methods for interfacing acoustic testing apparatus with acoustic probes and systems
First Claim
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.

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.
