Problems solved by technology
[0006] It can be seen that in the current cursor measurement operation, it is first necessary to switch the cursor line through a specific physical button or virtual button for selection, and then move the cursor line to the observation position by rotating the physical button or touching and sliding. There are many steps in this operation mode, and there is a problem of low operation efficiency
In addition, the display position of the cursor measurement information limits the user's visual observation range, and it is necessary to pause, rotate or slide to observe the current cursor measurement information, which is not conducive to the simultaneous realization of the adjustment process and the observation process, resulting in a poor user experience

The invention discloses a cursor touch control method and a cursor touch control device, and a digital oscilloscope, wherein, the cursor touch control device comprises a display unit, a contact detection unit, a cursor enable unit, a trajectory capture unit and a cursor adjustment unit, the cursor touch control device comprises a display unit, a contact detection unit, a cursor enable unit, a track capture unit and a cursor adjustment unit. As the display unit provides the display capability of the cursor on the touch screen, the corresponding display effect is formed between the cursor line and the information tag, which is convenient for the user to observe the measurement information on the cursor line and the corresponding information tag in real time. As the cursor enabling unit provides the selection condition of the cursor, the user can quickly select the cursor line and the corresponding information label, thus avoiding the situation that the user can select by using the entitykey or the virtual key in the past operation, and improving the operation efficiency of the user; As the cursor adjustment unit provides the convenient function of drag the cursor to adjust the position, the user can directly drag the cursor on the touch screen to realize the cursor measuring operation, and the effect of quickly adjust the position of the cursor is facilitated.
Description
technical field [0001] The invention relates to oscilloscope technology, in particular to a cursor touch method, a cursor touch device, and a digital oscilloscope. Background technique [0002] A digital oscilloscope is an electronic measuring instrument with a wide range of uses. It is an indispensable tool for the design, manufacture and maintenance of electronic equipment. It is known as the eyes of engineers, and it can quickly and accurately solve measurement challenges in various occasions. Digital oscilloscopes are increasingly popular because of their unique advantages such as waveform triggering, storage, display, measurement, and waveform data analysis and processing. The digital oscilloscope can convert various analog signals into digital signals, and display the voltage, current, frequency, phase difference, amplitude modulation and other parameters intuitively and vividly on the display through waveform, numerical and other display means, which can greatly facil...
