To
capture a single event
To
capture a single event, you need some previous 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 I
source
1.
Select a trigger source with the softkeys.
• Press I
slope/coupling
1.
Select a trigger slope with the
softkeys.
• Turn the Level knob to a point where you think the trigger should
work.
3 Press I
Mode
1,
then
press
the
single
softkey.
4 Press I
Erase
I to clear previous measurements from
the
display.
5 Press
I Run
1.
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.
