摘　　要：针对现有测频技术存在问题 ,提出一种新的测频方法 ,它是在测频测周的基础上 ,利用软件同步技术、测频测周双分界点及改变闸门时间的方法进行频率测量 ,从而大大提高准确度 。Considering some problems in current frequency measurement methods,a novel method for frequency measurement is presented. Based on the integration of frequency and period measuring method, this method utilizes software syntonization, two switch points and the lock gate period changed, and so it can to develop measurement accuracy and broad measurement range.

关 键 词：测频测周 频率测量 软件同步
