The pulse width and pulse duty cycle are correlative. Once a parameter is changed, the other will
be automatically changed. The pulse duty cycle is limited by the "Minimum Pulse Width" and
"Pulse Period".

Leading/Trailing Edge Time
The leading (rising) edge time is defined as the time required for the pulse amplitude to rise from
10% threshold to 90% threshold; while the trailing (falling) edge time is defined as the time
required for the pulse amplitude to fall from 90% threshold to 10% threshold as shown in the
figure above.
The range of the leading/trailing edge time is limited by the pulse width currently specified as
shown in the formula below. The edge time will be automatically adjusted to match the specified
pulse width if the value currently set exceeds the limit value.
Leading/Trailing Edge Time ≤ 0.625 × Pulse Width
