7 Select the qualifier time set softkey ( < or > ), then rotate the Entry
knob to set the pulse width qualifier time.
The qualifiers can be set as follows:
• 2 ns to 10 s for > or < qualifier (5 ns to 10 s for 350 MHz
bandwidth models).
• 10 ns to 10 s for >< qualifier, with minimum difference of 5 ns
between upper and lower settings.
Pulse width
trigger < qualifier
time set softkey
• When the less than (
<
) qualifier is selected, the Entry knob sets the
oscilloscope to trigger on a pulse width less than the time value
displayed on the softkey.
• When the time range (
><
) qualifier is selected, the Entry knob sets the
upper time range value.
Pulse width
trigger > qualifier
time set softkey
• When the greater than ( > ) qualifier is selected, the Entry knob sets the
oscilloscope to trigger on a pulse width greater than the time value
displayed on the softkey.
• When the time range ( >< ) qualifier is selected, the Entry knob sets the
lower time range value.
Video Trigger
Video triggering can be used to capture the complicated waveforms of
most standard analog video signals. The trigger circuitry detects the
vertical and horizontal interval of the waveform and produces triggers
based on the video trigger settings you have selected.
The oscilloscope's MegaZoom IV technology gives you bright, easily viewed
displays of any part of the video waveform. Analysis of video waveforms is
simplified by the oscilloscope's ability to trigger on any selected line of the
video signal.
