Abstract

The invention provides a display method for waveform of digital oscillograph and the digital oscillograph. It includes: wave form data collecting process or device to make the display data of display buffer before changing the horizontal timebase set as the data source of display data in changing the horizontal timebase; the waveform data zoom process or device is to zoom the display data on screen last time; waveform display process or device is to copy the zoomed data to the waveform display buffer in the state of digital oscillograph system stop and display it on screen. The invention is to display and treat the waveform data in changing the horizontal timebase by combining the collect data and waveform display of digital oscillograph to reflect the waveform data in time of changing the horizontal timebase.

Description

technical field [0001] The invention relates to digital oscilloscope technology, in particular to the waveform display processing technology of the digital oscilloscope when changing the system horizontal time base, specifically a digital oscilloscope waveform display method and the digital oscilloscope. Background technique [0002] In the prior art, the overall architecture of a digital oscilloscope generally includes (as shown in FIG. 1 ): an analog front end, an analog-to-digital converter, a control processor with a CPU, memory and logic circuits, a man-machine interface, a display, and a power supply. Among them, the analog front-end collects the measured signal through the probe, and transmits the collected analog signal to the analog-to-digital converter. The analog-to-digital converter converts the analog signal into a digital signal and transmits it to the control processor. Under the control of the control processor, Display digital signals. [0003] The digital ...
