How to Set the Trigger System

Trigger determines when DSO starts to acquire data and display waveform. Once
trigger is set correctly, it can convert the unstable display to meaningful waveform.
When DSO starts to acquire data, it will collect enough data to draw waveform on
left of trigger point. DSO continues to acquire data while waiting for trigger
condition to occur. Once it detects a trigger it will acquire enough data continuously
to draw the waveform on right of trigger point.
Trigger control area consists of 1 knob and 2 menu buttons.
Trigger Level: The knob that set the trigger level; push the knob and the level will be
set as the vertical mid point values of the amplitude of the trigger signal.
Force: Force to create a trigger signal and the function is mainly used in "Normal"
and "Single" mode.
Trigger Menu: The button that activates the trigger control menu.
