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 neighboring part, and displays them on the
screen. For the digital oscilloscope, it samples waveform continuously no matter
whether it is stably triggered, but only stable trigger can be stably displayed. The
trigger module ensures that every time base sweep or acquisition starts from the
user-defined trigger condition, namely every sweep is synchronous with the
acquisition and the waveforms acquired is overlapped so as to display the stable
waveforms.
Trigger settings should be based on the features of the input signal. To quickly
capture the desired waveform, you need to understand the signal under test. This
oscilloscope provides abundant trigger types that help you focus on the desired
waveform details.
