Title:
TRIGGER SYSTEM AND METHOD FOR OSCILLOSCOPE, OSCILLOSCOPE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/105059
Kind Code:
A1
Abstract:
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.
