Leading edge time, trailing edge time
Setting range 15.0 ns to 58.8 Ms (3 digits or 0.1 ns resolution)
Leading edge time and trailing edge time independently settable
Minimum setting value Largest of either 0.01% of period or 15 ns
Pulse width, leading edge time, trailing edge time limits
The pulse width time, leading edge time, trailing edge time, and period are mutually constrained
by the following equations.
The duty is converted from pulse width time / period.
(leading edge time + trailing edge time)
