How to set the Trigger System

Trigger is to determine when DSO starts to acquire data and waveform display.
Once trigger to be set correctly then it will convert the unstable display to
meaning waveform.
When DSO start to acquire data it will acquire enough data to form waveform on
left of trigger point. DSO continues to acquire data when it waits for trigger
condition happen. Once it detect out the trigger it will acquire enough data
continuously to form the waveform on right of trigger point.
Trigger control area consists of 1 knob and 3 menu keys.
TRIG LEVEL: The knob that set the trigger level; press the knob and the level
will be cleaned to Zero.
50%: The instant execute button setting the trigger level to the vertical midpoint
between the peaks 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.
Trigger Control
The oscilloscope provides two trigger types: single trigger and alternate trigger.
Single trigger: Use a trigger level to capture stable waveforms in two channels
Alternate trigger: Trigger on non-synchronized signals.
The Single Trigger and Alternate Trigger menus are described respectively as
follows:

Single trigger

Single trigger has four modes: edge trigger, video trigger, pulse trigger and slope
trigger.
It happens when a specified
Edge Trigger:
in the specified slope direction.
Video Trigger: Carry out field or line video trigger on the standard video signal.
Use this trigger type to catch pulses with certain pulse width.
Pulse Trigger:
Slope Trigger: The oscilloscope begins to trigger according to the signal rising or
falling speed.
The four trigger modes in Single Trigger are described respectively as follows:
1. Edge Trigger
An edge trigger occurs on trigger threshold value of input signal. Select Edge trigger
mode to trigger on rising edge, falling edge or rising & falling edge.
