When the ultrasonic probe is used, the spatial position of the probe is regulated under the microscope so that the probe tip contacts with the electrode of the ultrasonic transducer, thereby establishing electrical connection between the probe and the ultrasonic transducer, the probe is connected with a transmitting/receiving amplifier through a cable, and then the transmitting/receiving amplifier is connected to output to a signal acquisition device (such as an oscilloscope).

When measuring echo, firstly, the transmitting/receiving amplifier transmits ultrasonic excitation signals, excitation signals are applied to the electrodes of the ultrasonic transducer through the cable and the probe, so that the ultrasonic transducer is excited to transmit ultrasonic waves, the ultrasonic waves propagate in a medium and are reflected by the reflecting surface to form echo, the echo propagates back to the ultrasonic transducer through the medium, the ultrasonic transducer receives the echo and converts the echo into electric signals, the electric signals are transmitted to the transmitting/receiving amplifier through the probe and the cable for signal processing (such as signal amplification, filtering and the like), and finally, the electric signals are collected by the signal collecting device for measurement and analysis.
