Abrégé

A trigger system and method for an oscilloscope, an oscilloscope, and a storage medium. The trigger system for an oscilloscope comprises: a reference trigger signal generation module (11) and a trigger control module (12) which are connected to each other, wherein the reference trigger signal generation module (11) is configured to generate N reference trigger signals according to an initial trigger signal; and the trigger control module (12) is configured to sequentially delay the N reference trigger signals to form N target trigger signals, wherein the maximum delay in the delays respectively corresponding to the N target trigger signals is less than a period T of the initial trigger signal. A signal to be sampled that is input into the oscilloscope is pre-sampled on the basis of each target trigger signal to acquire N pieces of pre-sampled data, a trigger position is determined according to the N pieces of pre-sampled data, and the trigger position is sent to a sampling module (13) of the oscilloscope, such that the sampling module (13) samples, on the basis of the trigger position, the signal to be sampled that is input into the oscilloscope, so as to acquire a sampled signal.

Abrégé

Disclosed are a color generation system, method, and apparatus for an object to be displayed, a display device, and a medium. The color generation system for the object to be displayed comprises a module for processing an object to be displayed, a color setting module, and a color generating module. The module for processing the object to be displayed is configured to preprocess a sampled object to be displayed and determine information of object to be displayed of the sampled object to be displayed according to the preprocessed sampled object to be displayed. The color setting module is configured to generate, on the basis of the information of object to be displayed, a color mapping table of the object to be displayed, and analyze the information of object to be displayed and color information in the color mapping table of the object to be displayed to obtain a subpixel information component of a display interface. The color generating module is configured to configure, on the display interface according to the subpixel information component of the display interface, a display color of the sampled object to be displayed.

Abrégé

A digital oscillograph comprises a locus intensity synthesizer (303) with a first intensity memory (310) and a second intensity memory (320), and the control process (400) which it executes comprises a judging step (420) for judging whether the time interval of a trigger signal is greater than one predetermined threshold, a first fluorescence processing step（430）which is executed when the time interval of the trigger signal is less than or equal to the predetermined threshold and a second fluorescence processing step (440) which is executed when the time interval of the trigger signal is greater than the predetermined threshold. The digital oscillograph can automatically select a dynamic fluorescence effect and pay attention to the long-term change situation of signals on condition of lower trigger rate. It can automatically select a static fluorescence effect and pay attention to the fast change situation of signals on condition of higher trigger rate. The digital oscillograph has a compact structure and a higher waveform capture rate.
