Embodiment Construction

[0021] A digital oscilloscope and a waveform processing method thereof according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] figure 1 It is an explanatory diagram of the structure of the digital oscilloscope 100 according to the exemplary embodiment of the present invention.

[0023] refer to figure 1 , the digital oscilloscope 100 includes a measurement part 101 , a display control part 102 , a display part 104 , a trigger 105 and a central controller 106 .

[0024] The measuring component 101 receives the digital signal to be measured, and samples the digital signal. While outputting the measured digital signal to the flip-flop 105 , the measuring component 101 also outputs digital sampling signals corresponding to multiple sampled digital waveforms. It should be clear that the multiple waveforms are obtained from the same digital signal under test for multiple acquisitions successively,...

Abstract

The invention discloses a digital oscilloscope and a waveform processing method. The digital oscilloscope comprises a waveform acquisition part used for generating digital sampling signals of a plurality of digital waveforms according to the sequence of digital signals to be tested, and a display control part used for overlaying the plurality of digital waveforms according to the digital sampling signals of the digital waveforms, wherein the newest digital waveform is displayed in a first display attribute, and rest digital waveforms are displayed in a second display attribute. According to the digital oscilloscope, the newest digital waveform is displayed in the first display attribute, the rest digital waveforms are displayed in the second display attribute, therefore, a user can distinguish that which waveform is newest, and the digital oscilloscope is more convenient for use.

Description

technical field [0001] The application relates to digital oscilloscope technology, in particular to a digital oscilloscope and a waveform processing method. Background technique [0002] The display system of a traditional analog oscilloscope uses a cathode ray tube (Cathode RayTube, CRT). Because CRT has a good fluorescent effect, that is, the activation effect of phosphor powder, it will make the displayed waveform track from bright to dark over time, so that it can reflect the characteristics of two aspects of the waveform, one is the change of the track itself One is the frequency of trajectory recurrence. [0003] Most of the current display systems of digital oscilloscopes use liquid crystal display (LCD) screens. The screen is like a two-dimensional pixel array, and the position of each pixel can be uniquely determined by a row address and a column address. By controlling the "on" or "off" of each pixel, the pixels on the LCD display can be "bright" or "off" immedia...
