To capture a single event
To capture a single event, you need some knowledge of the signal in order to
set up the trigger level and slope. For example, if the event is derived from
TTL logic, a trigger level of 2 volts should work on a rising edge. The
following steps show you how to use the oscilloscope to capture a single
event.
1
Connect a signal to the oscilloscope.
2 Set up the trigger.
•
Press Source . Select a trigger source with the softkeys.
•
Press Slope/Coupling . Select a trigger slope with the softkeys.
•
Turn the Level knob to a point where you think the trigger should work.
3
Press Mode , then press the Single softkey.
4 Press Erase to clear previous measurements from the display.
5 Press Run .
Pressing the Run key arms the trigger circuit. When the trigger conditions
are met, data appears on the display representing the data points that the
oscilloscope obtained with one acquisition. Pressing the Run key again
rearms the trigger circuit and erases the display.
