To Set Rising/Falling Edge (Pulse)
The rising edge time is defined as the duration of the pulse amplitude rising from
10% to 90% threshold, while falling edge time is defined as the duration of the pulse
amplitude moving down from 90% to 10% threshold (as shown in the figure below).
The setting range of rising/falling edge time is limited by the currently specified pulse
width limit (as shown in the formula below). DG800 will automatically adjust the
edge time to match the specified pulse width if the value currently set exceeds the
limit value.
Rising/Falling Edge Time ≤ 0.625 × Pulse Width
Tap the RisEdge or FallEdge parameter input field. Use the numeric keypad to
input the desired value and then select the desired unit from the pop-up menu.

The pulse width units available are sec, msec, μsec, and nsec.

The rising and falling edge time are independent of each other, and users can
set them separately.
You can also use the arrow keys and the knob to set the parameter value: press
down the knob to enter the editing mode, use the arrow keys to move the cursor to
select the digit to be edited, and then rotate the knob to modify the value. Besides,
you can use the knob to switch between different parameters.
