Triggering the Oscilloscope 3
5000 Series Oscilloscope User’s Guide 103
To use Pulse Width triggering
Pulse Width (glitch) triggering sets the oscilloscope to trigger on
a positive or negative pulse of a specified width. If you want to
trigger on a specific timeout value, use Duration trigger in the
Trigger More menu.
1 Press the Pulse Width key in the Trigger section of the front
panel to display the Pulse Width trigger menu.
2 Press the Source softkey (or rotate the Entry knob on
mixed-signal oscilloscopes) to select a channel source for the
trigger.
The channel you select is shown in the upper-right corner of
the display next to the polarity symbol.
The source can be any channel available on your oscilloscope.
External trigger may also be specified as a source when using
a 2-channel oscilloscope.
Adjust the trigger level for the selected channel by turning
the Trigger Level knob. The value of the trigger level is
displayed in the upper-right corner of the display.
3 Press the pulse polarity softkey to select positive ( )or
negative ( ) polarity for the pulse width you want to
capture.
