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.

|
|
|
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 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.
