| Abstract: | Frequency response analysis has a wide usage as a method of system analysis. A frequency response analyzer based on LabVIEW is introduced in this paper. Compared with the traditional spectrum analyzer, it has many advantages such as a higher ratio of performance to price, wide usage, easy upgrade in performance, etc. The software and hardware structures of a frequency response analyzer are given, and its program realization is expounded in detail. Comparison with standard instrument has been carried out. Ex... |
