Chapter 5 To Trigger the Oscilloscope
As for trigger, you set certain trigger condition according to the requirement and
when a waveform in the waveform stream meets this condition, the oscilloscope
captures this waveform as well as the neighbouring part and displays them on the
screen. For digital oscilloscope, it samples waveform continuously no matter whether
it is stably triggered, but only stable trigger can ensure stable display. The trigger
module ensures that every time base sweep or acquisition starts from the
user-defined trigger condition, namely every sweep is synchronous to the acquisition
and the waveforms acquired overlap to display stable waveform.
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. This oscilloscope provides abundant advanced trigger functions which can
help you to focus on the desired waveform details.
