Embodiment Construction
[0047] The technical solution of the present invention will be described in detail below in combination with specific embodiments and accompanying drawings, so as to make it more clear.
[0048] Such as figure 1 As shown, the embodiment of the present invention provides an oscilloscope waveform zoom-in display method, which may include the following steps:
[0049] Step S101: After receiving the waveform zoom-in instruction, obtain the horizontal coordinates of the target zoom-in point moving in the horizontal direction of the display interface;
[0050] This step is mainly to receive the waveform zoom-in instruction, and obtain the horizontal coordinates of the target zoom-in point moving in the horizontal direction of the display interface according to the received waveform zoom-in instruction.
[0051] Before this step, you can set the trigger source, trigger level, horizontal time base and sampling rate of the oscilloscope. Among them, the sampling rate of the oscillosco...

The invention relates to an oscilloscope waveform amplification display method and system, a computer storage medium and equipment, and relates to the technical field of oscilloscopes, wherein the method includes acquiring the level of a target zoom point moving in the horizontal direction of a display interface after receiving a waveform zoom instruction. Coordinates, according to the horizontal coordinates of the target zoom-in point and the horizontal coordinates of the trigger point of the waveform of the current display interface, calculate the horizontal position difference between the target zoom-in point and the trigger point, wherein the trigger point is the waveform Amplify the symmetrical point, calculate the position coordinates of the new trigger point for waveform amplification according to the horizontal position difference, read the corresponding waveform data from the memory according to the new trigger point, and use the target zoom point as the symmetrical point to read The acquired waveforms are expanded and displayed on the display interface. The above-mentioned solution overcomes the problem that multiple operations or adjustments are required when the waveform is enlarged and displayed in the oscilloscope in the traditional technology, and reduces the operation complexity of the oscilloscope.
Description
technical field [0001] The invention relates to the technical field of oscilloscopes, in particular to a method and system for amplifying and displaying waveforms of an oscilloscope, a computer storage medium and equipment. Background technique [0002] An oscilloscope is an electronic measuring instrument with a wide range of uses. The oscilloscope can transform electrical signals into observable images, and can also obtain waveform curves of various signal amplitudes changing with time. [0003] When zooming in and displaying a waveform with an oscilloscope, the waveform is generally enlarged and expanded with a fixed trigger point. The fixed trigger point is the enlarged symmetrical point used as a symmetric reference during the waveform zoom-in process of the oscilloscope, and then moves the waveform to the target. The waveform appears on the display interface; or move the waveform to the display interface first, zoom in on the waveform with a fixed trigger point, and th...
