The trigger Mode and Conditioning... options are available in the Trigger dialog box
with all trigger types:
• Mode — Select Auto to automatically trigger when the specified trigger
condition has not occurred for some period of time. Select Trig'd to turn off
automatic triggering.
When triggers are not occurring, you can use the [Force] key to trigger on
anything, acquire, and display captured data.
• Conditioning... — These options include coupling (similar to analog input channel
coupling but affecting the trigger input only), holdoff, and external
(AUX TRIG IN) input options.
You can also open the Conditioning dialog box by choosing Trigger >
Conditioning... from the main menu.
