频率计的基本原理是用一个频率稳定度高的频率源作为基准时钟，对比测量其他信号的频率。通常情况下计算每秒内待测信号的脉冲个数，此时我们称闸门时间为1秒。闸门时间也可以大于或小于一秒。闸门时间越长，得到的频率值就越准确，但闸门时间越长则没测一次频率的间隔就越长。闸门时间越短，测的频率值刷新就越快，但测得的频率精度就受影响。本文数字频率计是用数字显示被测信号频率的仪器，被测信号可以是正弦波，方波或其它周期性变化的信号。如配以适当的传感器，可以对多种物理量进行测试，比如机械振动的频率，转速，声音的频率以及产品的计件等等。因此，数字频率计是一种应用很广泛的仪器.(The basic principle is the frequency with a frequency stability of high frequency source as a benchmark, compared to other signal measurement clock frequency. Usually calculated per pulse signal to the gate, we say the number 1 SEC. Time, Gate time can also is greater or less than a second. The longer gate, the more accurate were frequency value, but the gate is no longer a frequency measurement of interval is longer. Gate time is shorter, measurement of frequency value refresh the sooner, but the measurement accuracy frequency. Article. Digital frequency is measured by using digital display signal frequency instrument, the signal can be sine wave, square or other periodic change of signal. If using appropriate sensor, to test, such as the variation of mechanical vibration frequency, speed, and the voice of the frequency of product piece etc. Therefore, digital frequency is a kind of very wide application of instrument.)
