1. A testing device comprising a sending unit, a receiving unit, a control unit, a timing circuit, and a display,
wherein the control unit comprises a memory portion and an arithmetic portion,
wherein the sending unit is configured to output a pulse signal for a probe to generate an ultrasonic wave,
wherein the receiving unit is configured to generate a first signal including a first analog data on the basis of an input signal input from the probe and outputting it to the control unit,
wherein the memory portion is configured to store the first analog data,
wherein the arithmetic portion is configured to generate an image signal output to the display on the basis of the first analog data stored in the memory portion, and
wherein the timing circuit is configured to generate a first timing signal and a second timing signal in response to an instruction from the control unit,
wherein the sending unit is configured to output the pulse signal on the basis of the first timing signal, and
wherein the receiving unit is configured to sample the signal input from the probe on the basis of the second timing signal and generating the first signal comprising the first analog data,
wherein the display is configured to display an image based on the image signal.
