Key points
Trigger When. The pulse width of the source must be ≥5 ns for the oscilloscope
to detect the pulse.
When options Details
=
≠
Triggers the oscilloscope when the signal pulse width is equal to or not
equal to the specified pulse width within a ± 5% tolerance
<
>
Triggers the oscilloscope when the source signal pulse width is less than
or greater than the specified pulse width
Refer to the Application Examples chapter for an example of triggering on
aberrant pulses. See Triggering on a specific pulse width on page 42.
Trigger frequency readout
The oscilloscope counts the rate at which triggerable events occur to determine
trigger frequency and displays the frequency in the lower right corner of the
screen.
NOTE. The trigger frequency readout shows the frequency of events the
oscilloscope might consider to be a trigger, and may be less than the frequency of
the input signal in Pulse Width trigger mode.
