Trigger Position (POSITION), Trigger Delay (DELAY), Trigger Hold-Off (Holdoff)
These items are the same as those of the edge trigger.
• The instrument may not trigger properly if the spacing between signals or the time detection width is less
than 1 ns.
• Under standard operating conditions, the time accuracy immediately after calibration is as follows:
CH1 to CH4: ±(0.002% of setting + 450 ps)
LOGIC: ±(0.002% of setting + 1 ns)
Window Trigger [ENHANCED]
Window refers to a range set by upper level and lower level. The instrument triggers when the waveform moves
from inside (IN) the window to outside (OUT) the window or from outside (OUT) to the inside (IN) or when the
relationship between the time that the waveform stays in the IN or OUT condition and the specified reference
time meets the selected time condition. When the time condition is timeout, the instrument triggers when a
timeout occurs.

Trigger Source (Source)
Select the trigger source from the following: CH1 to CH4. (The selectable settings vary depending on the model.)
Configure the trigger slope, HF rejection, noise rejection, and trigger level settings for the selected trigger source.
Polarity (Polarity)
Select the polarity from the following. The polarity varies depending on the time condition.
• Without a time condition
When the trigger source level enters the specified range (window)
When the trigger source level goes outside of the specified range (window)
• With a time condition
When the trigger source level remains inside the specified range (window)
When the trigger source level remains outside the specified range (window)
