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 overtime trigger): The oscilloscope triggers
when a pulse continues longer than the time specified as the Pulse Width.
Pulse Width Range Selectable from 20ns to 10s
Slope Trigger
Slope Trigger Mode
Trigger when < (Less than), > (Greater than), = (Equal), or ≠ (Not Equal);
Positive slope or Negative slope
Slope Trigger Point
Equal: The oscilloscope triggers when the waveform slope is equal to the
set slope.
Not Equal: The oscilloscope triggers when the waveform slope is not
equal to the set slope.
Less than: The oscilloscope triggers when the waveform slope is less
than the set slope .
Greater than: The oscilloscope triggers when the waveform slope is
greater than the set slope .
Time Range Selectable from 20ns to 10s
Overtime Trigger The leading edge: Rising edge or Falling edge; Time Setting: 20-10s
Swap Trigger
CH1 Internal Trigger: Edge, Pulse Width, Video, Slope
CH2 Internal Trigger: Edge, Pulse Width, Video, Slope
Trigger Frequency
Counter
Readout Resolution 6 digits
Accuracy (typical) ± 30ppm (including all frequency reference errors and ± 1 count errors)
Frequency Range AC coupled, from 4Hz 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, including
when the oscilloscope acquisition pauses 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 1 s 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 mode: The oscilloscope counts all edges of sufficient
magnitude and correct polarity.
Video Trigger mode: The Frequency Counter does not work .
