Maximum Input Voltage

CAT I and CAT II: 300VRMS (10×)

CAT III: 150VRMS(1×);

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. Excursion above 300V should be of less than 100ms duration. RMS signal level including all DC components removed through AC coupling must be limited to 300V. If these values are exceeded, damage to the oscilloscope may occur.

Signal Formats and Field Rates, Video Trigger Type

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.
