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.
