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 highmeasurement accuracy, butalso in the frequency measurement accuracy of the frequency bandwidth can be keptconstant.As a result of the front-end circuit and good isolation circuit and other technical measures, and In a wide rangeof frequencies in the range of frequency and amplitude, period, duty cycle and other parameters were measuredaccurately, and can be preset by adjusting the gate time measurement accuracy. After experimental verification and datameasurement, results show that our scheme is feasible and can achieve highermeasurement accuracy in a widebandwidth.
