The trigger of the oscilloscope can synchronize the horizontal scanning of the signal at the correct position and make the signal characteristic clear.Trigger control buttons stabilize repeated waveforms and capture single waveforms.
Most of the oscilloscope for users to use only edge-triggered way, if you have other triggered ability is very useful in some applications, especially for the new design product fault search, advanced triggered concerns events can be separated and find out you are concerned about abnormal problem, thus the most efficient use of sampling rate and depth of the storage.
Today there are many oscilloscopes with advanced triggering capabilities.Trigger ability mainly around three aspects: (1) the vertical direction of the amplitude, example transient spike trigger, over pulse or short pulse trigger, etc.; (2) the horizontal direction and time related trigger, such as pulse width, narrow pulse, establish/hold time and other set time width trigger form; (3) the combination ability of extension and conventional trigger function. For example, for video signal or other signals that are difficult to capture, trigger conditions are set through the combination of time and amplitude to trigger. The improvement of the triggering ability CAN greatly improve the flexibility of the testing process and simplify the work. In particular, the triggering ability of the oscilloscope to the data bus is greatly improved, such as CAN, I2C, etc.
