Waveform acquisition is crucial in the design of acoustic emission instruments for research fields. It can be said that with waveforms, everything is possible. Waveforms can be used to extract acoustic emission parameters, and waveforms can be used for FFT and wavelet transforms. The DS2AE series All information AE system achieves multi-channel synchronous acquisition of acoustic emission waveforms. This feature is different from conventional acoustic emission instruments.

     1) DS2AE series AE system: does not set the acquisition length, continuously collects waveforms, and automatically stops when the specified acquisition time is reached. The waveform data of all channels is automatically aligned according to time.

    2) Conventional acoustic emission instrument: Set the acquisition length after triggering, collect each channel separately after triggering, and manually adjust the alignment according to the arrival time.
