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 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.
