Figure 3-7 Signal afer reducing random noise
Example 6: Capture a Single signal
To capture a single event, it needs to gather some pre-test knowledge of the signal in
order to set up the trigger level and slope correctly. For example, if the event is derived
from TTL logic, a trigger level of 2 Volts should work on a rising edge.
Do these steps as followings:
1. Set the probe and the channel attenuations to 10X.
2. Press the key TRIG to show the Trigger menu.
3. Select Mode->Edge. Set Source to CH1 and Slope to Rising. Set Sweep to Single.
4. Adjust the Volts/Div and the time base in a proper range for the signal.
5. Drag the trigger level sign on the waveform display screen.
6. When the trigger conditions are met, data appears on the display representing the
data points that the Scope Meter obtained with one acquisition.
