Abstract

The invention discloses a frequency measuring machine and a method for measuring the frequency of a signal, wherein the frequency measuring machine is used for carrying out frequency division processing on an input radio-frequency signal through an arranged frequency divider; thus, a frequency-divided signal with lower frequency is obtained; therefore, an analog-digital collection module is enabled to be capable of collecting the frequency-divided signal; thus, the frequency measuring machine is enabled to be capable of being applied to the frequency measurement of a radio-frequency signal with higher frequency; in addition, in a frequency calculation module, the further digital detection and shaping filtering treatment is carried out on a complex signal through a digital detection unit; the pulse edge of an obtained detected signal is enabled to be steeper; the recognition and the processing of a sampling unit on each effective pulse are convenient; the frequency measurement precision of the frequency measuring mechanism is increased.

Description

technical field [0001] The invention relates to the technical field of signal frequency measurement, in particular to a frequency measuring machine and a method for measuring signal frequency. Background technique [0002] Signal frequency measurement (frequency measurement) is one of the most basic measurements in electronics. Common frequency measurement technologies in the prior art mainly include multi-channel frequency measurement technology, frequency discrimination method frequency measurement technology, and interferometer phase comparison method. Technology and digital calculation method frequency measurement technology, among them, due to the low frequency measurement accuracy of multi-channel frequency measurement technology and frequency discrimination method frequency measurement technology, and the large volume of the instrument used in the interferometer comparison method, the digital calculation method Frequency technology has become a widely used frequency m...
