    频率计

    频率计也叫频率计数器是用于测量频率的电子仪器。它们通常测量周期电子信号中的每秒振荡数或脉冲数。频率计易于使用,您只需打开计数器,然后施加信号到输入端。从数字逻辑信号到射频和微波信号,它们可用于测量多种信号。

    频率计的应用:

    • 测量发射器载波的频率
    • 测量电路振荡器的频率
    • 测量线路信号的频率
    • 需要测量稳定重复信号频率的任何应用

    频率计的工作原理

    频率计的工作原理主要包括信号输入、垂直系统、采样、频率计算和结果显示五个步骤。在信号输入后,频率计通过垂直系统对信号进行处理,然后进行采样。采样后的数据通过频率计算得到信号的频率,最终结果显示在屏幕上。

    频率计的应用条件

    • 频率必须稳定,不变化
    • 不得对信号进行调制,否则计数会不正确
    • 信号必须有足够的振幅 - 通常是信号超过电压的一半为宜
    • 信号不应过大导致输入过载

    频率计是一种易于使用的测试仪器,几乎不会出现故障,能够提供精确的结果。
