The Research of Pulse Signal Parameter Measuring Instrument Based on FPGA and STM32
Using the principle of measurement accuracy, combined with EDA technology and microcomputer control technology, we designed the pulse signal measuring instrument. The accuracy of frequency the measurement method not only has high measurement accuracy, but also in the frequency measurement accuracy of the frequency bandwidth can be kept constant.As a result of the front-end circuit and good isolation circuit and other technical measures, and In a wide range of frequencies in the range of frequency and amplitude, period, duty cycle and other parameters were measured accurately, and can be preset by adjusting the gate time measurement accuracy. After experimental verification and data measurement, results show that our scheme is feasible and can achieve higher measurement accuracy in a wide bandwidth.
