Abstract


This paper discusses the development of low-cost high-precision phase seized broadband frequency meter purpose and specific implementations . The frequency meter phase inspection broadband frequency measurement technology designed to overcome the counting error of ± 1 word , to achieve high-precision frequency measurement in a wide frequency range , and your costs lower level . This design uses a new type of phase coincidence points detection circuit to improve the accuracy of phase coincidence detection . Frequency standard external atomic frequency standard built - in high - voltage regulator control crystal , and reduce the cost of the instrument instead . Additional standard frequency calibration function to ensure high measurement accuracy can also use relatively high rate of aging high- voltage regulator controlled crystal oscillator case . The instrument phase coincidence points detection and counting part in the FPGA chip programming design , reduce system complexity and cost , improve reliability , and enhance the confidentiality , which can effectively protect the intellectual property of the developer . FPGA ALTERA 's Cyclone series FPGA chip , using EDA tools Quartus Ⅱ 6.0 development . Calculates and displays the work is mainly done by the MCU MCU optional 89C51 microcontroller ATMEL Corporation MCS-51 series LCD module with MCU control the display of the instrument display . Practice has proved that the frequency meter has the advantages of low-cost , high-precision , high integration and high reliability , with enterprise production and market-oriented promotion .
