5 To Trigger the Oscilloscope
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 circuit
ensures that every time base sweep or acquisition starts from the input signal and
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.
