Holdoff Range 100ns ~ 10s

Pulse Width Trigger

Pulse Width Trigger Mode Trigger when (< , >, = , or ?); 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 overtime trigger): The oscilloscope triggers when a pulse continues longer than the time specified as the Pulse Width

Pulse Width Range 20ns ~ 10s

Slope Trigger

Slope Trigger Mode Trigger when (< , > , = , or ? ); 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.

Trigger Frequency Counter

Readout Resolution 6 digits

Accuracy (typical) 30ppm (including all frequency reference errors and 1 count errors)

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.
