Use the input box to set parameters such as the span, center frequency, start frequency, and stop frequency of the spectrum analyzer. This parameter setting method is not intuitive, and requires a certain estimation of the relevant parameters of the signal of interest. In order to accurately select the desired signal interval.

In addition, the embodiments of the present invention set the parameters of the spectrum analyzer based on the effective use of the peripheral mouse of the PC, which is fast and efficient and can greatly improve the usability of the spectrum analyzer.

During specific implementation, the relevant parameters of the spectrum analyzer are set through the actions on the spectrum analyzer display screen presented by the mouse on the PC, and the mouse actions can include:

Select the area, that is, click the mouse to select the starting area, drag it to the desired ending area, and then release the mouse;

Move the area, that is, click the mouse to determine the moving point, and drag to the desired stop point, and then release the mouse.

Use the above-mentioned mouse operations to complete the setting of parameters such as the reference level, center frequency, start frequency, and stop frequency of the spectrum analyzer.

In one embodiment, step 201 obtains the operation data of the mouse on the display screen of the spectrum analyzer, which may include: obtaining the coordinate data of the area selected by the mouse on the display screen of the spectrum analyzer; Operating the data and setting the parameters of the spectrum analyzer may include: according to the coordinate data of the area selected by the mouse on the display screen of the spectrum analyzer, modify the horizontal axis span or vertical axis span on the display screen of the spectrum analyzer to obtain the modified spectrum The reference level and scale value on the display screen of the analyzer; the modified reference level and scale value on the display screen of the spectrum analyzer are set to the spectrum analyzer.

In this example, by operating the mouse on the selected area on the display screen of the spectrum analyzer, you can set the span of the horizontal axis or the span of the vertical axis on the display screen of the spectrum analyzer, and then obtain the reference level and Scale the value and set to the spectrum analyzer. After setting these parameters to the spectrum analyzer, it may further include: receiving data collected by the spectrum analyzer according to the set parameters.

An example is given to illustrate the above process of setting the span. As shown in Figure 3, in this example, focus on the signal within a certain span (signal 1 in Figure 3), which is completed by selecting the area with the mouse.

Figure 3 and Figure 4 show the horizontal and vertical span settings, while the vertical axis span (reference level, scale) setting in the horizontal direction is similar to the operation shown in Figure 3 and Figure 4 .

In one embodiment, step 201 obtains the operation data of the mouse on the display screen of the spectrum analyzer, which may include: obtaining the coordinate data of the moving area of the mouse on the display screen of the spectrum analyzer; Operating the data and setting the parameters of the spectrum analyzer may include: according to the coordinate data of the mouse moving area on the display screen of the spectrum analyzer, modify the signal position displayed on the display screen of the spectrum analyzer to obtain the modified display screen of the spectrum analyzer Center frequency, start frequency, stop frequency, reference level and scale value on the screen; set the center frequency, start frequency, stop frequency, reference level and scale value on the modified spectrum analyzer display screen to spectrum analysis instrument.

In this example, by operating the mouse on the moving area on the display screen of the spectrum analyzer, the signal position displayed on the display screen of the spectrum analyzer can be set, and then the center frequency, start frequency, Stop frequency, reference level and scale value and set to spectrum analyzer. After setting these parameters to the spectrum analyzer, it may further include: receiving data collected by the spectrum analyzer according to the set parameters.

Give an example to illustrate the above-mentioned process of setting the displayed signal position on the display screen of the spectrum analyzer. This process can be considered as the position change of the "spectrum display window" (display screen of the spectrum analyzer). The span (horizontal axis and vertical axis) on the screen remains unchanged, but the center frequency, start frequency, stop frequency, reference level and scale value have changed. This operation can be understood as setting the position of the "spectrum display window", without changing the size of the "spectrum display window", but only modifying the position of the "spectrum display window" on the frequency band. As shown in Figure 5, the operation of the moving region by the mouse is completed, and the coordinate data of the moving region of the mouse on the display screen of the spectrum analyzer is obtained after the operation (the coordinate data indicates the position information of the "spectrum display window"), according to the Coordinate data modify the signal position displayed on the display screen of the spectrum analyzer, obtain the center frequency, start frequency, stop frequency, reference level and scale value on the display screen of the modified spectrum analyzer and set them to the instrument end (lower computer) , the lower computer will collect data according to the setting and send it back to the PC upper computer, and get the display signal position setting results shown in Figure 6. The part of the rectangular mark in Figure 5 is the moving fixed point, based on which it moves to the right and down (pointed by the arrow in Figure 5). Figure 5 is the final display result of the movement.

In this example, by operating the mouse on the selected area on the display screen of the spectrum analyzer, the size of the display screen of the spectrum analyzer can be set, and then the center frequency, start frequency, stop frequency, and reference frequency on the display screen of the spectrum analyzer can be obtained. Level and scale values and set to the spectrum analyzer. After setting these parameters to the spectrum analyzer, it may further include: receiving data collected by the spectrum analyzer according to the set parameters.

An example is given to illustrate the setting process of the size of the display screen of the above-mentioned spectrum analyzer. This process can be considered as setting the "spectrum display window" (that is, the display screen of the spectrum analyzer), specifically modifying the size of the "spectrum display window" within a certain frequency band. As shown in Figure 7, the operation of the selected area by the mouse is completed, and the coordinate data of the area selected by the mouse is obtained after the operation (the coordinate data indicates the size information of the "spectrum display window"), and the display screen of the spectrum analyzer is modified according to the coordinate data size, get the center frequency, start frequency, stop frequency, reference level and scale value on the modified spectrum analyzer display screen and set them to the instrument end (lower computer), and the lower computer will collect data according to the settings and transmit Go back to the PC host computer to get the size setting result of the spectrum analyzer display screen shown in Figure 8. It can be seen that there are three relatively large signals in Figure 7, and these signals are selected through the selected area operation of the mouse, and Figure 8 shows the display status of these three signals in a new window.
