Maximum Input Voltage

CAT I and CAT II: 300 VRMS (10×), Installation Category;
CAT III: 150 VRMS (1×);
Installation Category II: derate at 20 dB/decade above 100 kHz to 13 V peak AC at 3 MHz and above. For non-sinusoidal waveforms, peak value must be less than 450 V. Excursion above 300 V should be of less than 100 ms duration. RMS signal level including all DC components removed through AC coupling must be limited to 300 V. If these values are exceeded, damage to the oscilloscope may occur.

Holdoff Range

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

20 ns to 10 s

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.
