ASTRO-MED Dash 8X - Trigger Setup and Data Capture Exercise

III. Trigger Setup and Data Capture:
In the Data Capture Settings section above, a ten second capture was set up with two seconds of pre-trigger (data before
the trigger). In this section, a trigger level of 8 Volts will be set with a rising slope so that as the signal rises and reaches 8
Volts, the data capture will be triggered.
