The dashed line pulse in the following figure shows how increased transition time can affect the rising
edge and falling edge of the pulse. The shaded areas of the pulse show the changes in the slopes.
Notice that the pulse width interval is not affected. If the transition time is increased, the pulse would
not reach its programmed amplitude (100%).

Rise Time
The rise transition time for the pulse output.
Fall Time
The fall transition time for the pulse output.
Pulse Delay
The pulse delay is the time interval between the start of the rising pulse edge of the trigger output
pulse and the output pulse. You can set the rising or falling polarity of the trigger output pulse edge to
the output pulse. The pulse delay has a variable delay with respect to the trigger output.
