Oscilloscope signal display processing method and oscilloscope

The invention discloses an oscilloscope signal display processing method and an oscilloscope. The envelope line is extracted while the waveform image is drawn; the envelope line is stored in an internal storage unit; if the hardware configuration of the oscilloscope is not adjusted, the waveform image is directly displayed; if hardware configuration of the oscilloscope is adjusted, the envelope line stored in the internal storage unit is processed and is then displayed according to the adjusted configuration parameters; and thus, when the hardware configuration is changed, the envelope line ofthe last frame of waveform under the pre-stored old hardware configuration is processed and then displayed according to the new configuration parameters, the phenomenon that the oscilloscope displayscreen does not display the waveform for a long time after the hardware configuration of the oscilloscope is changed is avoided, and the user experience is improved. 本发明公开了一种示波器信号显示处理方法及示波器，由于在绘制波形图像的同时提取其包络线，并将包络线存储在内部存储单元中，若
