Level (Level), HF Rejection (HF Rejection), Noise Rejection (Noise Rejection)
Set these items for the trigger source.
These items are the same as those of the edge trigger.
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)
Rise/Fall Time Trigger [ENHANCED]
The instrument triggers when the relationship between the trigger source’s rising or falling times and the
specified reference times meets the selected time condition.

Trigger Source (Source)
Select the trigger source from the following: CH1 to CH4. (The selectable settings vary depending on the model.)
Configure the polarity, HF rejection, noise rejection, and trigger level settings for the selected trigger source.
Polarity (Polarity)
Select which trigger source polarity will cause the comparison of the pulse width with the reference times. The
trigger source polarity is based on the trigger level.
When the trigger level passes through the lower limit and then reaches the upper limit (rising)
When the trigger level passes through the upper limit and then reaches the lower limit (falling)
When a rising or falling edge is detected
