| Abstract: | The advanced DASP (Data Alias-free Signal Processing) technology is applied to modern test instrument platform. By choosing sample point positions properly and improving signal processing arithmetic, the problem of high frequency signal reconstruction with less sample points is solved. The characteristics of anti-aliasing and eliminating aliasing frequency spectrum noise permit detecting signals with different amplitudes. The researches indicate that applying DASP technology in test instrument platform can extract high frequency signals with lower sampling rate effectively, and improve test precision and efficiency. |

| Keywords: | DASP technology test instrument platform non-uniform sampling pseudo-random signals with lower sampling |
