Abstract: Methods and devices are disclosed for testing an acoustic probe having transducing elements for converting between acoustic and electrical signals. An electrical signal is generated at a frequency with a testing device capable of generating electrical signals over a range of frequencies. The electrical signal is transmitted to at least some of the transducing elements to measure a complex impedance and thereby evaluate a performance of the transducing elements.
