Abstract: The groundwork and approach in its implementation of low frequency comprehensive test instrument were presented. The instrument uses touch monitor to finish the signal distortion, phase difference measurement and weak signal detection. The instrument designed base on the virtual instrumentation idea, and it has he characteristics of simple operating, easy carrying and accurate measuring.
Key words: Data acquisition, Distortion, Phase, Weak signal
