The system uses STM32F103VCT6 MCU as the control core, and realizes a double-phase signal generator that can generate two channel rectangular wave or sine wave and the amplitude, frequency, duty ratio and phase difference are all adjustable. The entire system consists of STM32 system with TFT-LCD and keyboard input module and extern conditioning circuit. The system can realize the base function of signal generator with high precision so that it can be applied into basic electronic measure area.
