4.2 Capturing a Single-Shot 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 3.3V COMS logic, a trigger level of 1.2 or higher Volts should work on a rising edge.
Do these steps as follows:
1. Set the probe and the channel attenuations to X 10.
2. Set up the trigger in the Trigger Menu, or in the Trigger Setting window.
1) Adjust the Trigger Mode to Edge.
2) Set the Trigger Sweep to Single.
3) Set the Trigger Source to CH1.
4) Set the Trigger Slope to “+” which means you select the rising edge.
5) Adjust the Volts/Div and the time base in a proper range for the signal.
