cursor measurement menu. In the bottom menu, select Window as the Main or
Extension to make the cursor line appear in the main window or magnifier window.
How to Set the Trigger/Decoding 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 rotary control and 2 menu buttons.
Trigger Level
: The rotary control that set the trigger level; push the rotary
control 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 three trigger types: single trigger, logic trigger and bus
trigger. Each type of trigger has different sub menus.
Press Trigger
Menu
panel button, then bottom menu Trigger Type, select Single,
Logic or Bus Trigger on the popup right menus, turn the M rotary control to
choose different trigger types.
Single trigger
: Use a trigger level to capture stable waveforms in two channels
simultaneously.
Logic trigger
: Trigger the signal according to the condition of logic relationship.
Bus trigger
: Set bus timing trigger.
The
Single Trigger, Logic Trigger
and
Bus Trigger
menus are described
respectively as follows:
Single Trigger
Single trigger has eight types: edge trigger, video trigger, pulse trigger, slope trigger,
runt trigger, windows trigger, timeout trigger and Nth edge trigger.
Edge Trigger
: It occurs when the trigger input passes through a specified voltage
level with the specified slope.
