Problems solved by technology

[0006] 1. Two cursors must be opened and the difference calculated;
[0007] 2. You must find the required position by yourself, which will cause the problem of inaccurate position positioning and affect the measurement accuracy;
[0008] 3. The statistical data within the dwell time must be calculated after collecting all the data, which is troublesome to operate;
[0009] 4. In order to obtain accurate data, the details must be enlarged, that is, to adjust the horizontal axis setting, which is difficult to operate

Abstract

The invention provides a method for achieving a cursor for frequency hopping signal time-frequency characteristic measurement. The method comprises the steps that firstly, the transverse axis position of the cursor is obtained from a user interface; secondly, the point where the cursor is located is found according to an array of the obtained transverse axis position and transverse axis data points in track data, and a target frequency is determined; thirdly, array index numbers of needed points are found forwards and backwards; fourthly, the time-frequency characteristic of a frequency hopping signal is calculated according to the found index numbers; fifthly, the time-frequency characteristic is sent to the interface. By means of the scheme, on the basis of a carrier frequency measurement function of a modulation domain analyzer, the stay time of the frequency of the current cursor of the frequency hopping signal, the current frequency mean variance and other common frequency parameters and the hopping time that the current frequency hops into another frequency can be directly measured as long as the cursor is put within the frequency hopping band needing observation. The operation is greatly simplified for a user, the measurement information can be accurately given, and the calculation amount is reduced for the user.

Description

technical field [0001] The invention belongs to the technical field of realizing a cursor for measuring the time-frequency characteristic of a frequency-hopping signal, and in particular relates to a method for realizing a cursor for measuring the time-frequency characteristic of a frequency-hopping signal. Background technique [0002] Frequency hopping signals are more and more widely used in the field of communication, how to measure the stability of frequency hopping signals becomes very important. In the modulation domain, the time-frequency characteristics of the frequency-hopping signal can be observed most intuitively and effectively. However, the existing software is very troublesome to measure the time-frequency characteristics of the frequency hopping signal, and some characteristics cannot be measured. Therefore, based on the carrier frequency measurement of the existing modulation domain analyzer, a simple and efficient time-frequency measurement of the frequenc...
