Abstract
Systems, apparatuses, and method of measuring hydrophone impedance are provided herein. A sensor can convert an acoustic wave received via a liquid medium into an electric signal. A signal encoder can be coupled with the sensor to receive the electric signal. A test signal generator can be coupled in series with the sensor and the signal encoder and can generate a test signal. The test signal can measure an impedance of the sensor. A switch component can be coupled in series with the sensor, the signal encoder, and the test signal generator. The switch component can route the test signal to a first terminal of the sensor and through a second terminal of sensor during a first operational state. The switch component can route the test signal to the second terminal of the sensor and through the first terminal of sensor during a second operational state.
