Abstract

The invention relates to an oscilloscope with a rotatable display screen, which includes a data acquisition unit, a drawing processing unit, a central processing unit and a touch display unit, wherein the data acquisition unit is for external signal input, and the input signal Processing a set of digital waveform data, the drawing processing unit is connected with the central processing unit and the data acquisition unit, and has a waveform processing unit, the waveform processing unit is controlled by the central processing unit to enable a first coordinate waveform processing module and one of the second coordinate waveform processing modules, which process the digital waveform data into the waveform display interface corresponding to the first or second coordinate, and then display it on the touch display unit; in this way, the waveform display interface switches coordinates again to perform When rotating, it can be achieved by switching the first and second coordinate waveform processing modules through the hardware circuit, without the coordinate conversion operation of the software, and the update rate is improved.

Description

technical field

[0001] The invention relates to a portable measuring instrument, in particular to a portable digital oscilloscope with display screen rotation function. Background technique

[0002] An oscilloscope is an instrument used to measure electronic signal waveforms. It is widely used in testing and researching electronic signals and characteristic curves of electronic components.

[0003] The internal circuits of existing oscilloscopes are mainly as Figure 10 shown, which contains:

[0004] A data acquisition unit 70, which has a group of signal input ports 71 for external signal input, and after signal amplification, sampling and analog-to-digital conversion, a group of digital waveform data is obtained and output;

[0005] A drawing processing unit 80 is connected with the data acquisition unit 70, and after receiving the digital waveform data, processes the digital waveform data into a waveform display screen output;

[0006] A central processing unit 90 is c...
