A controllable high-power electromagnetic seismic source system for shallow earthquake is composed of main controller and exciting unit. Under the control of industrial control PC, the DDS generates pulse signals, which can trigger counter and waveform storage to release digital waveforms. Going through D / A converter and filter, they are output to power amplifier for driving exciter to generate vibration and send it in ground. The earthquake signal is picked up by sensor and then compared with the predefined waveforms stored in PC, so forming a closed control loop. Its advantages are high saefty, high repeatability of signals, and wide frequency sweep range (5-1400 Hz).
