Window Trigger
The window trigger provides two trigger voltage levels, high and low. The oscilloscope triggers
when the input signal enters or exits the defined voltage window.
There are two kinds of window types: Absolute and Relative. They have different trigger level
adjustment methods.
• Absolute Window Trigger: The lower and the upper trigger levels can be adjusted via the
Level knob.
• Relative Window Trigger: Adjust the Center value to set the window center. Adjust the
Delta value to set the window height. The lower and the upper trigger levels will move
together.

 If the lower and the upper trigger levels are both within the waveform amplitude range, the
oscilloscope will trigger on both rising and falling edges. This will display two traces on the
screen.
 If the upper trigger level is within the waveform amplitude range while the lower trigger level
is outside of the waveform's amplitude range, the oscilloscope will trigger on the rising edge
only.
 If the lower trigger level is within the waveform amplitude range while the upper trigger level
is outside of the waveform's amplitude range, the oscilloscope will trigger on the falling edge
only.
Setting Window Trigger via Absolute window type:
1. Press the Setup button on the front panel to enter the TRIGGER menu.
