| 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.

| 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 |

| 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. |
