b) Select the "Select" mode, then set the specified line and the specified field to trigger
the signal. Assuming that the "Field" is set to 8, you can select any field from 1 to 8,
and each field can choose any line from 1 to 100.
15.5.6 Window Trigger
The window trigger is similar to the edge trigger, except that it provides an upper and a lower trigger
level. The instrument triggers when the input signal passes through the upper level or the lower level.
There are two kinds of window types: Absolute and Relative. They have different trigger level
adjustment methods. Under the Absolute window type, the lower and the upper trigger levels can be
adjusted separately. The relative window provides adjustment for the Center value to set the window
center and the Delta value to set the window range. In this mode, the lower and the upper trigger
levels always 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.
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 the 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 the falling edge only.
To set window trigger via the Absolute window type
Refer to "Adjust Upper/Lower Level" in the section "Slope Trigger".
