In the test process, the PCB board with the accelerometer to be tested is horizontally fixed on the vibration table, and the software control system generates a sine wave excitation signal with a certain frequency, which is amplified by a power amplifier and then excited to generate a certain acceleration in the Z-axis direction, so that the cantilever beam of the accelerometer to be tested is deformed and the electromechanical conversion is realized.
