Specifications
DSO8000E Series HandHeld Oscilloscope User Manual 84
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
Alter 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 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.
Acquisition
Acquisition Modes
Normal, Peak Detect, and Average

Normal, Peak Detect
Upon single acquisition on all channels
simultaneously
Average
After N acquisitions on all channels
simultaneously, N can be set to 4, 8, 16, 32, 64
or 128
