Trigger System
The trigger determines when the oscilloscope starts to acquire data and
display waveforms. Once the trigger is set correctly, it can convert an unstable
display into a meaningful waveform.
When the oscilloscope starts to acquire data, it first acquires enough data to
draw the waveform on the left side of the trigger point. The oscilloscope
continuously acquires data while waiting for the trigger condition to occur.
When a trigger is detected, the oscilloscope continuously acquires enough
data to draw a waveform on the right of the trigger point.
The trigger mode of this series of oscilloscopes is edge trigging.
The edge trigging mode is to trigger on the trigger electrical level of the edge of
the input signal, that is, trigger on the rising and falling edges of the input
signal.
Entering the edge trigging, the trigger setting information is displayed at the
