Abstract： In order to improve the accuracy, integration and flexibility of the system, a pulse signal parameter measurement system based on system-on-a-programmable-chip(SOPC) is designed. The system realizes the frequency measurement by using the equal precision frequency measurement method， and the duty cycle and rise time measurement are realized by using the equivalent pulse counting method. The designed measurement system is programmable in hardware and software. After testing and verification, the system can realize the measurement of pulse signal frequency, duty cycle, amplitude and rise time. The measurement results have high accuracy, and the time measurement accuracy can reach 1 ns.
