A properties screen—the channel LED glows green and you can once again trigger the
channel.
10. On the Triggering tab, choose Retrigger N times, set N=5, then click Apply. Depress
and hold the external trigger button. As long as the trigger is depressed (i.e., the input
signal is high) the channel will continue to trigger until the limit is reached.
11. Click the Reset button on the Channel A properties screen.
12. Again on the Triggering tab, select Rising Input (Edge Trigger) then click Apply.
Depress and hold the external trigger button. The channel will trigger only once, no
matter how long you hold the button. Release the external trigger button and depress it
again, and the channel will be triggered once more (switch bounce may produce triggers
when the button is released).
13. On the Delay tab, check Inverted output, then click Apply. The output will be the
inverse of that described in Step 4.
14. On the Sweep tab, select the Sweep Delay Box, then set the sweep to 0.5 s per trigger. To
deselect, click the top radio button.
15. Click Apply. The time delay before the output pulse will increase with each trigger.
