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 displays waveform continuously no matter whether
it is stably triggered, but only stable trigger can ensures stable display. The trigger
module guarantees that each time base sweep or sample starts when the input
signal meets the trigger condition defined by users; namely each sweep and sample
are synchronous and the waveforms acquired overlap to display a 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 types which can
help you to focus on the desired waveform details.
