Pulse Width Trigger
Pulse Width Trigger modes
Trigger when < (Less than), > (Greater than), = (Equal), or
≠
(Not Equal);
Positive pulse or Negative pulse.
Pulse Width Trigger Point
Equal:
The oscilloscope triggers when the trailing edge of the pulse crosses the trigger level.
Not Equal:
If the pulse is narrower than the specified width, the trigger point is the trailing
edge. Otherwise, the oscilloscope triggers when a pulse continues longer than the time
specified as the Pulse Width.
Less than:
The trigger point is the trailing edge.
Greater than
(also called time-out trigger): The oscilloscope triggers when a pulse continues
longer than the time specified as the Pulse Width.
Pulse Width Range
Selectable from 33 ns to 10 s
Pulse Width Resolution
16.5 ns or 1 part per thousand, whichever is larger

Trigger Frequency Counter
Readout Resolution
6 digits
Accuracy, typical
±
51 ppm including all frequency reference errors and
±
1 count errors
Frequency Range
AC coupled, 10 Hz minimum to rated bandwidth.
Signal Source
Pulse Width/ Edge Trigger:
all available trigger sources.
Frequency Counter
measures trigger source at all times, including when the oscilloscope
acquisition is halted due to changes in the run status, or acquisition of a single shot event
has completed.
Pulse Width Trigger:
The oscilloscope counts pulses of significant magnitude inside the 250
ms measurement window that qualify as triggerable events, such as narrow pulses in a PWM
pulse train if set to < mode and the width is set to a relatively small time.
Edge Trigger:
The oscilloscope counts all edges of sufficient magnitude and correct polarity.
Video Trigger:
The Frequency Counter does not operate.
