Referring to fig. 1, the present application discloses a digital oscilloscope 1, where the digital oscilloscope 1 mainly includes a display 11, a first response unit 12, a second response unit 13, and a driving configuration unit 14, which are respectively described below.

The first response unit 12 is in signal connection with the display 11 for causing one or more configuration items to be displayed on the interface in response to a first input by a user at the interface. It should be noted that the display 11 has a human-computer interaction function, and a user may perform human-computer interaction with the display 11 by operating the control panel, or may perform human-computer interaction in a screen touch manner, so as to implement an input operation on an interface of the display 11.
The second response unit 13 is in signal connection with the display 11 and the first response unit 12, and is configured to respond to a second input of the user on the interface, set each configuration item, and generate configuration information. Similarly, the user can perform human-computer interaction by operating the control panel or the screen touch mode to realize the operation of the second input.
The configuration driving unit 14 is in signal connection with the display 11 and the second response unit 13, and is configured to configure a part of the windows in the associated multiple windows according to the configuration information generated by the second response unit 13, and display the configured windows in real time through the interface, and display the non-configured windows in an overlapping manner.
It should be noted that, in this embodiment, the first response unit 12, the second response unit 13, and the driving configuration unit 14 are all functional components of the digital oscilloscope 1, and may be a processor implementing corresponding functions, or a programmable logic device (FPGA) implementing corresponding functions, and are not limited specifically here.
In this embodiment, a toolbar (or menu bar) may be formed on the interface of the display 11, and the user may trigger the toolbar through a key or touch operation (e.g., an operation of a first input), so that the first response unit 12 controls the display 11 to display one or more configuration items on the interface in response to the first input, for example, to display one or more configuration items in a drop-down list of the toolbar.
In a particular embodiment, referring to fig. 2, the one or more configuration items of the interface display include one or more of a horizontal configuration item, a vertical configuration item, and a grid configuration item. Wherein, the horizontal configuration item may contain some setting functions in the horizontal direction, such as one or more of Tdiv setting, delay setting, min/max setting, and horizontal ruler grid number setting; the vertical configuration items may include some setting functions in the vertical direction, such as one or more of Vdiv setting, offset setting, min/max setting, vertical ruler grid number setting; the grid configuration items may include some setting functions related to grid display, such as one or more of a numeric display type setting, a grid movement type setting, a start coordinate point setting, a long-wide pixel setting.
In the horizontal arrangement item, Tdiv denotes an amount of time expressed by each grid on the horizontal scale, delay denotes an amount of time delayed, min/max in the horizontal direction denotes a minimum/maximum value of time, and the number of grids on the horizontal scale denotes a total number of the grids on the horizontal scale. In the vertical arrangement item, Vdiv refers to the amount of voltage indicated by each cell on the vertical scale, offset refers to the amount of voltage offset, min/max in the vertical direction refers to the minimum/maximum value of voltage, and the number of cells on the vertical scale refers to the total number of cells on the vertical scale.
It should be noted that, in the grid configuration project, the configuration information may be generated through some settings, such as: the method comprises the steps of setting information whether a selected horizontal scale and a vertical scale generated through a numerical value display type label numerical values or only label maximum values, minimum values and central values, setting information whether the selected horizontal scale generated through a grid movement type moves along with an interface trigger position and/or whether the selected vertical scale moves along with an offset central position of an activation channel and selecting information whether the numerical values are fixed to move, setting information of coordinates of a selected initial coordinate point generated through an initial coordinate point, and setting information of selected length pixel values and width pixel values generated through long and wide pixels.
In this embodiment, it can be seen from fig. 3 that the configuration driving unit 14 comprises a frame management module 141, and the frame management module 141 is configured to manage a plurality of frames associated with the configuration information, where the plurality of frames include a menu frame, a grid frame, and a waveform frame.
In one embodiment, see fig. 4, the menu frame is used to form a first display area on the interface (such as a right area, a left area, an upper area, a lower area, or a combination of areas of the interface), and the measurement status of the signal is displayed in the first display area through a plurality of status bars. The grid window is used for forming a second display area (such as the central area or the right area of the interface) on the interface, and the gear of the signal is displayed through the horizontal scale and/or the vertical scale. The waveform window is used for forming a third display area on the interface, the third display area is overlapped with the second display area of the grid window, and the waveform of the signal is displayed in the third display area. To fully utilize the interface resources, the first display area and the second display area may be combined into a complete interface for the display 11. It should be noted that the menu window, the grid window, and the waveform window are independent of each other, and each of them realizes different display functions for different display contents, but can be displayed in a superimposed manner on the interface, and what is finally presented to the user is the display contents after being superimposed.
Further, referring to fig. 3, the configuration driving unit 14 further includes a display configuration module 142 and a display driving module 143. The display configuration module 142 is configured to manage a plurality of configuration items, where the plurality of configuration items include a horizontal configuration item, a vertical configuration item, and a grid configuration item; specifically, the display configuration module 142 is configured to convert the configuration information in real time, and reset the display parameters of the grid window, the waveform window, or the menu window for configuration. The display driving module 143 is configured to drive and display a display area corresponding to the configured window on the interface by using the display parameter, and superimpose and display a display area corresponding to an unconfigured window on the interface.
For example, the frame management module 141 configuring the driving unit 14 generates display layers of a menu frame, a mesh frame, and a waveform frame, which are displayed in superposition on the interface of the display 11. When a user needs to configure a part of the form, a first input operation may be performed in a first display area corresponding to the menu form, and the first response unit 12 retrieves parameters of horizontal configuration, vertical configuration, and grid configuration in the display configuration module 142, and generates horizontal configuration items, vertical configuration items, and grid configuration items in the first display area. Then, the operation of the second input may be performed on the displayed respective configuration items, providing a setting operation for the respective setting options in each configuration item. The second response unit 13 generates corresponding configuration information when setting a setting option in a configuration item, and sends the generated configuration information to the display configuration module 142 in real time, and the display configuration module 142 performs real-time conversion on the configuration information and resets the display parameters of the corresponding window. If the configuration information of each time quantum of the generated horizontal scale is set through Tdiv, adjusting each grid display parameter of the horizontal scale on the grid window, and correspondingly adjusting the display width of the signal waveform in the waveform window in the horizontal direction to adapt to the adjustment of the horizontal scale; if the configuration information generated by setting the grid movement type selects the vertical scale to move along with the offset center position of the activation channel and selects a fixed numerical value to move, adjusting the movement mode of the vertical scale on the grid window; for example, the configuration information of the selected length pixel value and the width pixel value generated by the length-width pixel setting may be used to scale the size of the second display area corresponding to the grid window, and simultaneously scale the first display area corresponding to the menu window to be suitable for the display areas other than the second display area, and scale the third display area corresponding to the waveform window to be suitable for the second display area. Finally, the display driving module 143 drives and displays the display areas (e.g., the second display area and the third display area) corresponding to the configured frames in real time, and superimposes and displays the display areas (e.g., the first display area) corresponding to the non-configured frames.
For example, 50ms and 10ms are respectively selected by Tdiv setting and delay setting in the horizontal configuration item; respectively selecting 10mv and 5mv through Vddiv and offset settings in a vertical configuration item; the horizontal scale and the vertical scale are marked with numerical values by the numerical value display type setting in the grid configuration item, so that the grid window can be configured in real time to form the grid as shown in fig. 7. In addition, on the basis of real-time configuration of the grid window in fig. 7, the horizontal scale may be selected to move along with the interface trigger position through the grid movement type setting in the grid configuration item, and the vertical scale is selected to move along with the offset center position of the activation channel, so that when the user touches the display on the interface and causes sliding, the moved grid as shown in fig. 8 may be formed.
Those skilled in the art can understand that the digital oscilloscope claimed in the present application can collect configuration information generated by a user during an input operation through a menu window in a window management module, and can timely deliver the configuration information to a display configuration unit, so that the configuration information is fed back to a grid window and a waveform window to complete a function of driving display in real time, which is beneficial to operations such as scaling, moving, numerical value display and the like on a grid or signal waveform on an interface, thereby achieving a better human-computer interaction effect and improving the user experience of the digital oscilloscope.
