Trigger
For trigger, you set certain trigger condition according to the requirement. When
a waveform in the waveform stream meets this condition, the oscilloscope
captures this waveform and the neighboring part and displays them on the
screen. Still, the digital oscilloscope displays waveform continuously no matter
whether it is stably triggered, but only stable trigger can ensure stable display.
The trigger circuit ensures that every time base sweep or acquisition starts from
the input signal and the user-defined trigger condition. Every sweep is
synchronous to the acquisition and the waveforms acquired overlap to display
stable waveform.
The following is the schematic diagram of the acquisition memory. As shown in
the figure below, the position of the trigger event is determined by the reference
time point and the delay setting.
Trigger setting should be based on the features of the input signal, thus you need
to have some knowledge of the signal under test to quickly capture the desired
waveform.
The oscilloscope provides abundant advanced trigger functions which can help
you to focus on the desired waveform details. These trigger types are edge, slope,
pulse, video, window, interval, dropout, runt, pattern and serial trigger. This
chapter will mainly introduce all these trigger functions mentioned above in
detail and tell you how to set the trigger conditions to capture the desired
waveform.
