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.
Trigger Control
The oscilloscope provides two trigger types: single trigger, alternate
trigger. Each type of trigger has different sub menus.
Single trigger: Use a trigger level to capture stable waveforms in
two channels simultaneously.
Alternate trigger: Trigger on non-synchronized signals.
The Single Trigger, Alternate Trigger menus are described
respectively as follows:
Single Trigger
Single trigger has two types: edge trigger, video trigger.
Edge Trigger: It occurs when the trigger input passes through a
specified voltage level with the specified slope.
Video Trigger: Trigger on fields or lines for standard video signal.
The two trigger modes in Single Trigger are described respectively
as follows:
