Abstract: According to definition of narrow signal-noise ratio and analysis of measurement method,it is found that spectrum of the signal and data acquiring have the function with the measurement precision.This paper compared the double axis synchronous data acquiring,single axis identical voltage data acquiring and single axis identical interval data acquiring with each other,and found that the last one can obtain the highest test precision.
