Problems solved by technology
[0007] For the existing automatic cursor tracking method, if the user expects to visually observe other waveform characteristics, the tracked measurement item needs to be set as the last measurement item, so additional operations such as resetting the measurement item are required, and the steps are cumbersome
It can be seen that when users want to pay attention to multiple waveform characteristics of the measured signal, the existing digital oscilloscopes cannot provide a simple and easy-to-use operation method to track multiple measurement items, that is, they cannot Mark the measurement boundaries of multiple measurement items

The invention provides an oscilloscope with an automatic cursor tracing function, which is used for displaying acquired waveform data on a display interface in a waveform display manner. The oscilloscope comprises a measurement unit, a control key and a display control unit, wherein the measurement unit is used for measuring the waveform data for multiple times according to a plurality of measurement items set by a user to acquire a measurement boundary of each measurement item; the control key is used for selecting one of the measurement items and generating measurement item selection information corresponding to the selected measurement item; and the display control unit is used for acquiring the measurement boundary of the corresponding measurement item according to the measurement item selection information, and marking a cursor on the display interface according to the acquired measurement boundary. According to the oscilloscope, the control key can be used for selecting the measurement item traced by the cursor; the display control unit acquires the measurement boundary of the corresponding measurement item according to the selection of the different measurement items by the user; the cursor marking the measurement boundary can conduct tracing switching among the different measurement items; the measurement items are not required to be reconfigured as that in the prior art; and the oscilloscope is simple and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of test and measurement, in particular to an oscilloscope with automatic cursor tracking function. Background technique [0002] An oscilloscope is a commonly used electronic measurement tool. In the process of using an oscilloscope, users often need to pay attention to various waveform characteristics of the measured signal. Modern oscilloscopes can provide a variety of built-in measurement functions. By setting different measurement items, such as: amplitude, period, rise time, duty cycle etc., to assist the user in measuring and analyzing the waveform characteristics of the signal under test. Specifically, the oscilloscope converts the measured signal into waveform data, and then measures the waveform data according to the measurement items set by the user to obtain the measurement boundary of each measurement item. Finally, according to the measurement boundary, the waveform data is obtained. The measu...
