Waveform signal generator

The invention discloses a waveform signal generator, which belongs to the technical field of electronics and comprises a shell. A waveform generation device, a rotation driving device and a signal acquisition device are arranged in the shell. At least one round high-frequency trigger ring is arranged on the upper portion of the waveform generation device and composed of trigger blocks which are evenly distributed, the trigger blocks are permanent magnets or magnetic steel, and the polarities of every two adjacent trigger blocks in the same direction are different. The signal acquisition deviceis provided with a Hall sensor used for acquiring a signal of a magnetic field so as to form a periodic waveform signal. The generator has the beneficial effects that the frequency and the amplitudeof an output signal can be adjusted conveniently, a negative voltage signal can be generated, and operation, transformation, maintenance and repair are facilitated. 本发明公开了一种波形信号发生器，属于电子技术领域，包括壳体，其内部设有波形发生装置、转动驱动装置和信号采集装置。波形发生装
