Vector network analyzer for entity key touch control

Abstract

The invention provides a vector network analyzer for entity key touch. The vector network analyzer adopts a full-screen touch screen; a touch area of the full-screen touch screen is independently arranged on the right side of the full-screen touch screen. For the realization of the touch area, a keyboard value response event is triggered by sending a keyboard button event to trigger a simulation keyboard API function Keybd _ event (), or a non-keyboard value response event of touch keys is realized through data transmission among a server, a receiving end and a sending end. According to the invention, the physical key touch of the vector network analyzer can be realized, and the requirement of one button for realizing multiple functions can be met by setting the virtual key value of the sending key, so that the burden of a user on interface design is reduced; and on the basis, the touch key panel can be displayed or hidden as required, so that more humanized design is realized, and meanwhile, the panels with the same size can be more flexibly suitable for different requirements.

Description

technical field [0001] The invention relates to a vector network analyzer, in particular to a touch-sensitive vector network analyzer with physical keys. Background technique [0002] Physical buttons are also called physical buttons. Physical buttons are physical buttons that need to be pressed; for example, the panel buttons of a vector network analyzer are basically physical buttons. [0003] At present, the vector network analyzers on the market are basically the display + physical key area: due to the limitation of the size of the meter, the display for users to view and edit is relatively small, and it is difficult for users to observe the changes of graphics, and the operation on graphics is also difficult. It is inconvenient; because the graphic display area is relatively small, the overall graphic display is relatively small. Since the graphic display is relatively small, the user needs to be more careful to observe the trace changes on the graphic, and it is also d...

Problems solved by technology

[0003] At present, the vector network analyzers on the market are basically display + physical button area: due to the limitation of the size of the instrument, the real display for users to view and edit is relatively small, and it is also difficult for users to observe changes in graphics, and operations on graphics are also difficult. Inconvenient; because the graphic display area is relatively small, the overall graphic display is relatively small. Since the graphic display is relatively small, the user must carefully observe the trace changes on the graphic, and it is also difficult for the user to drag the mark on the interface.

In the prior art, it is also possible to enlarge the screen through computer remote login, but it is inconvenient to operate
