6.11 Activating a Width (Pulse<T, Pulse>T, T1<PLS<T2, and Time Out) Trigger (ENHANCED)
Status of Each Channel
• The status (H, L, and X) is the same as A->B(N) trigger when Window is OFF. See
section 6.8.
• The status (IN, OUT, and X) is the same as the window trigger when Window is ON.
For a description of window triggers, see section 6.13.
Setting the Trigger Level
Selectable range: Eight divisions of the screen.
Resolution:
0.01 divisions: For example, the resolution for 2 mV/div is 0.02 mV.
Setting the Hysteresis
Sets a width to the trigger level so that triggers are not activated by small changes in the
trigger signal.
:
Approximately 0.3 divisions* of hysteresis around the trigger level.
:
Approximately one division* of hysteresis around the trigger level.
*
The value above is an approximate value. It is not strictly warranted.
Setting the Trigger Coupling
You can select from the following.
AC: Uses a signal that is obtained by removing the DC component from the trigger
source signal.
DC: Uses the trigger source signal as-is.
Turning the HF Rejection ON and OFF
Specify 15 kHz or 20 MHz if you wish to use a signal that is obtained by removing the
high frequency components (frequency components greater than 15 kHz or 20 MHz)
from the trigger source signal as the trigger source.
Setting the Determination: Time
The selectable range is 1 ns to 1 s, and the resolution is 1 ns.
Relationship with Window
When Window is turned ON, a trigger is also activated on the time over which the
parallel pattern of the window condition (IN, OUT, or X) of each channel is met or not
met. For details on the window trigger, see section 6.13, “Setting the Window Trigger.”
Setting the Hold Off
See section 6.4, “Setting the Hold Off Time.”
Notes on Setting the Width Trigger
The trigger may not operate correctly if the interval between pulses or the pulse width of
the signal is less than 2 ns. The time accuracy of the pulse width under standard
operating conditions after calibration is
±
(0.5% of s 1 ns). However, the setting
for T1<PLS<T2 is the T2 value.
