Window Trigger
Windows trigger provides a high trigger level and a low trigger level. The instrument triggers
when the input signal passes through the high trigger level or the low trigger level.
There are two kinds of window types: Absolute and Relative. They have different trigger
level adjustment methods. Under Absolute window type, the lower and the upper trigger
levels can be adjusted respectively via the Level knob; under Relative window type,
adjust the Center value to set the window center; adjust the Delta value to set the window
range, the lower and the upper trigger levels always move together.
Horizontal Trigger Position
High Level
Low Level
If the lower and the upper trigger levels are both within the waveform amplitude
range, the oscilloscope will trigger on both rising and falling edge.
If the upper trigger level is within the waveform amplitude range while the lower
trigger level is out of the waveform amplitude range, the oscilloscope will trigger
on rising edge only.
If the lower trigger level is within the waveform amplitude range while the upper
trigger level is out of the waveform amplitude range, the oscilloscope will trigger
on falling edge only.
To set window trigger via Absolute window type:
1. Press the
Setup
button on the front panel to enter the TRIGGER function menu.
2. Press the
Type
softkey; then use the
Universal Knob
to select
Window
and push
down the knob to confirm.
3. Press the

the trigger source.
4. Press the Window
Type
softkey to select Absolute.
5. Press the
Lower Upper
softkey to select
Lower
or
Upper
trigger level; then turn the
Trigger Level Knob
to adjust the position. The trigger level values are displayed at
the upper right corner of the screen.
The Lower trigger level cannot be upper than the upper trigger level. In the trigger
state message box,
L1
means the upper trigger level while
L2
means the lower
trigger level.
