Using the Trigger

Using the Trigger

The trigger can be used to start capturing data after a specified digital event occurs.

Two types of triggers are supported: Trigger on Edge and Trigger on Pulse Width.

The trigger can be used to trigger on an event from any channel. To move the event trigger to a different channel, first remove it using the steps at the bottom of this page, and then add it to a different channel. 

Trigger on Edge

To trigger on an edge (high to low, or low to high digital transition), click the +Trigger button on the desired channel and select the positive or negative edge.

If desired, you can also require other channels to be either high or low during a previously selected edge. After selecting an edge, note that other channels will display a button with an "X" (indicates "don't care").

To require a high or low, click this button and select high or low.

Trigger on Pulse Width

You can also trigger on a pulse width condition where a particular channel is high or low for a specified amount of time.

To add a pulse width trigger, click the +Trigger button on the desired channel and select the positive or negative edge. Next, enter the desired time range to search for.

If desired, you can also require other channels to be either high or low during a previously selected pulse. After selecting an edge, note that other channels will display a button with an "X" (indicates "don't care"). To require a high or low, click this button and select high or low.

Start Searching for the Trigger

After setting the trigger, you can click the Start or Start Simulation button to begin searching for the trigger. If and when the trigger condition is identified, data collection will start.

Skipping the Trigger

You can skip the trigger by clicking "skip trigger" if you would like to force the capture to begin without the trigger condition being met.

Stopping the Capture

If the trigger condition is identified, data collection will start. You can stop the capture at any point in time by clicking "Stop". This will stop the recording and will keep any data that has already been recorded.

Searching with a Trigger

After data have been collected, you can search for events within the data using the trigger. The trigger can be added or modified after data have been collected.

After the trigger has been set up (see above) and data have been collected, left and right arrows will appear next to the trigger button on the channel used for the edge or pulse width condition. Click these arrows to advance to sections of the data that satisfy the trigger condition.

Turning Off the Trigger

To remove the trigger, deselect the trigger type button, or use the reset button.
