Spectrum analyzer method and device for moving cursor

The embodiment of the invention provides a spectrum analyzer method and device for moving a cursor. The method comprises the following steps that: detecting a pressing event in real time; when the initial position of the pressing event is in an area where the cursor belongs to, detecting whether the pressing event is a dragging operation or not, wherein the dragging operation means that the initial position of the pressing event is different from the end position of the pressing event; when a detection result shows that the pressing event is the dragging event, obtaining the coordinate of theend position of the pressing event; according to the coordinate of the end position of the pressing event, obtaining a measurement value corresponding to the coordinate; and drawing the cursor on theobtained measurement. By use of the scheme, the cursor can be efficiently and conveniently moved through the dragging operation. 本发明实施例提供了种频谱分析仪、移动光标的方法及装置，其中，该方法包括：实时检测按下事件，当所述按下事件的初始位置在光标的所属区域内时，检测所述按下事件是否为拖动操作，所述拖动操作是指按下事件的
