To try validated trigger mode:
1. On the General Settings screen, select 100/64 (low-resolution) mode for Channels A and
B.
2. Click OK to save the change. A warning may appear listing channels for which the
clock range settings are invalid. Click OK to close the warning. The software will go into
“offline” mode allowing you to adjust the timing settings for the listed channels.
3. In Channel A’s properties screen, select Validated Trigger Input mode.
4. On the Validate tab, enter a Minimum duration and Duration of output pulse of 1
second each.
5. On the Triggering tab, select Retrigger N times, and set N=50.
6. Click OK.
7. Go “online” and click Program > Program all channels.
8. Now, depress the external trigger button (connected via BNC). If you hold the button
down for more than one second (the minimum duration), the output of Channel A will go
high. If you release the button before one second elapses, the output will remain low and
the channel will wait for another input pulse.
