Integration of a variety of waveform generator function, adjustable amplitude, frequency parameters, to meet the different requirements. The circuit has perfect protection function, high safety and reliability. At the same time, the device also has analog signal position control input port, easy to integrate with other digital and analog control signals. Operation mode transformation can also be controlled through the external interface. The upper computer communication software can set parameters such as voltage and displacement. It can be used in the field of high reliability system such as tilt, pitch, yaw / differential drive.
