| Abstract: | Frequency spectrum measures of circuit network are studied in this paper by means of varied-frequency pseudo-random code instead of the traditional sweep signal. The pseudo-random codes are generated by the Electronic Design Automatic (EDA) technique. The high speed ADC and FIFO techniques are investigated for data acquisition and storage. A Single Chip Microcomputer (SCM) is adopted to control the signal generation,acquisition and communication with the computer. The Labview is used for signal process and graphics display to make up a measure system with high performance for data acquisition and frequency spectrum analysis. |
