Chapter 5 Trigger

Chapter 5 Trigger
To generate a trigger, you set a trigger condition according to the requirement; when
a waveform in the waveform stream meets this condition, the oscilloscope captures
this waveform as well as the neighbouring part immediately and then displays the
captured waveforms on the screen. The digital oscilloscope samples waveform data
continuously no matter whether it is stably triggered; but only a stable trigger can
guarantee stable waveform display. The trigger circuit guarantees that each time
sweep and sample start 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. The 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 waveform
details of interest.
