Trigger Polarity
Each pulse generator can be individually configured for rising or falling
edge triggering. Even if multiple pulse generators are using the same
trigger, each can have different polarities.
Figure 3-2 shows the output of a pulse generator configured to look for a
rising edge trigger and output a high pulse with a microsecond width and
delay.
