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.
