摘要

A new frequency standard comparison system is proposed based on the group quantization phase processing. By shortening the width of phase coincidence fuzzy area and capturing the best group phase coincidences, we reduce the randomness of the counting gate and improve the measurement precision of the comparison system. The method is based on the Field programmable gate array (FPGA), which not only retains the advantage using phase synchronization detection technology to overcome the +/- 1-word counting error, but also accelerates the system response time, simplifies the measurement equipment, and reduces the development cost and power consumption. The experimental results show that the method is reasonable and scientific, and the comparison accuracy of the system can reach the E-12 level, obviously superior to the measurement accuracy of the traditional frequency standard comparison method, which has a wide application and popularization value.
