DSO4000 Series Digital Storage Oscilloscope
Trigger when < (Less than), > (Greater than), = (Equal), or ≠ (Not Equal);
Positive slope or Negative slope
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.
Selectable from 20ns to 10s
The leading edge: Rising edge or Falling edge; Time Setting: 20-10s
Internal Trigger: Edge, Pulse Width, Video, Slope
Internal Trigger: Edge, Pulse Width, Video, Slope
6 digits
± 30ppm (including all frequency reference errors and ± 1 count errors)
AC coupled, from 4Hz minimum to rated bandwidth
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 1s 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.
