Installation Category II: derate at 20dB/decade above 100kHz to 13V peak AC at 3MHz* and above. For non-sinusoidal waveforms, peak value must be less than 450V.

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.
