Table 6: Pulse Width Trigger Specifications
Characteristics Description
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 s pecified as
the Pulse Width.
Less than: The trigger point is the trailing edge.
Greater than (also called time-out trigger): The oscilloscope triggers w hen a pulse continues
longer than the time specified as the Pulse Width.
Pulse Width Range
Selectablefrom33nsto10s
Pulse Width Resolution 16.5 ns or 1 part per thousand, whichever is larger
Equal Guardband t > 330 ns: ±5% ≤ guardband < ±(5.1% + 16.5 ns)
t ≤ 330 ns: guardband = ±16.5 ns
Not Equal Guardband t > 330 ns: ±5% ≤ guardband < ±(5.1% + 16.5 ns)
165 ns < t ≤ 330 ns: guardband = -16.5 ns ÷ +33 ns
t ≤ 165 ns: guardband = ±16.5 ns
Table 7: Trigger Frequency Counter Specifications
Characteristics Description
Readout Resolution 6 digits
Accuracy (typical) ±51 parts per million including all frequency reference errors and ±1 count errors
Frequency Range
AC coupled, 10 Hz minimum to rated bandwidth
Signal Source
Pulse Width or Edge Trigger modes: all available trigger sources
The Frequency Counter measures trigger source at all times in Pulse Width or Edge m odes,
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 mode: 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 i s set to a relatively small time.
Edge Trigger mode: The oscilloscope counts all edges of sufficient magnitude and correct polarity.
Video Trigger mode: The Frequency Counter does not operate.
