STEVAL-IME013V1(Ultrasound Pulser Waveform Demo)output waveforms has the sharp burrs.

I try to generate pulses using STEVAL-IME013V1.The power supply information is as follows:VDD=+5V DCVSS=-5V DCHVM=+10V DCHVM_CW=-10V DCActually the board can generate the preset waveforms by the power supply.Show as the figure.But I am curious at the...

AcousticSL Software Library AcousticSL_Handler_t Struct Reference clarification
