摘要 以FPGA为核心的高速高精度的频率测量,不同于常用测频法和测周期法。本文介绍的测频方法,不仅消除了直接测频方法中对测量频率需要采用分段测试的局限,而且在整个测试频段内能够保持高精度不变。又由于采用FPGA芯片来实现频率测量,因而具有高集成度,高速和高可靠性的特点。 The high precise measurement technique based on FPGA is different from frequency measurement or period measurement. This paper presents the way of frequency measurement not only eliminat ion of direct frequency measurement method for measuring frequency required by subparagraph Inter test, but also in the entire test frequency can be maintained within the same precision, because FPGA chip to achieve frequency measurement, Hence, it has high integration, high speed and high reliability features.
