Signal Formats and Field Rates

Supports NTSC, PAL and SECAM broadcast systems for any field or any line

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)

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.
