Method for realizing user interface and waveform combination and oscilloscope

The invention discloses a method for realizing user interface and waveform combination and an oscilloscope. User interface data represented by RGB values is converted into user interface pixel data ina central processing unit. The user interface pixel data is used for identifying an attribute of each pixel point on the display interface so that identification is performed according to a functional area where each pixel point on the display interface is located; and a programmable logic device receives the user interface pixel data and waveform pixel data, then clock alignment is performed, and then combination can be directly performed in the programmable logic device according to the attribute of each pixel point of the display interface so that the combination of the oscilloscope user interface and the waveform is realized in the programmable logic device in a hardware mode, the central processing unit is not required to participate in processing and is not limited by the performance of the central processi
