Abstract

The invention discloses a spectrometer-based peak searching system and method. The system comprises a data collecting unit, a data processing unit and a data display unit. The method comprises 1) obtaining n spectral data within a fixed frequency range and transmitting the spectral data to the data processing unit through the data collecting unit; 2) computing the left threshold value and the right threshold value of the n data; 3) in the data processing unit, from the first spectral datum of the n spectral data, sequentially comparing the data with the left threshold value, and when the value Xa of an ath spectral datum is greater than the left threshold value, from the value Xa of the ath spectral datum, sequentially comparing the data with the right threshold value; 4) from a bth spectral datum, repeating operations of the step 3); 5) comparing the maximum value within every peak range through comparison by the data processing unit. The spectrometer-based peak searching system and method can solve the technical problems of inaccurate peak searching, small searched peak quantity, incapability of accurately determining positions of peaks and influence of small protrusions on peak searching results.

Description

technical field [0001] The invention relates to the field of communication testing, in particular to a spectrum analyzer-based peak search system and method. Background technique [0002] The spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation degree, spectral purity, frequency stability and intermodulation distortion. It can be used to measure certain parameters of circuit systems such as amplifiers and filters. , is a multipurpose electronic measuring instrument. [0003] In the prior art, the one-dimensional golden section method is generally used to search for the peak value. This method is mainly: if the function f(x) has and only one maximum value is located on the interval (a,c), when a< When b<c, then f(b)>f(a) and f(b)>f(c). At this time, if a point x is selected on the interval (b,c), when f(b)>f(x), then f(b)>f(a) and f(b)>...
