Example 3: Capture a Single-Shot Signal
To capture a single event, you need to gather some pre-test knowledge of the signal
in order to correctly 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 the MENU button in the Trigger control area to display the menu.
·
Press Edge to select trigger mode
·
Press Slope
to select
Rising
·
Press Source to select
CH1
·
Press Mode to select
Single
·
Press Coupling to select
DC
·
Turn the vertical and horizontal SCALE knobs to adjust the Volts/Div and the Time
base in a proper range for the signal
·
Turn the LEVEL knob to adjust trigger level
3. Press RUN/STOP button to start capturing
When the trigger conditions are met, data appears on the display representing the
data points that the oscilloscope obtained with one acquisition. Press the RUN/STOP
button again rearms the trigger circuit and erases the display.
