| Abstract: | To satisfy the non-linear distortion measurement for wide band frequency especially in low frequency, the comparison of base band restraint and harmonic analysis method that were used in non-linear distortion measurement usually was put forward in this paper. Some principles of measuring were given. The suitable application of the two methods was analyzed. It was showed that using Agilent 89441A VSA to measure the non-linear distortion could overcome the disadvantages of some traditional spectrum analyzers and audio analyzers. |
