Duty
Variable range selectable Normal, extended (selectable)
Normal range Duty can be changed in range with little jitter and no pulse loss.
The higher the frequency, the narrower the duty setting range.
Extended range With 2.5 ns rms or less typ. jitter, duty can be changed always in
maximum range. In the case of a pulse width of 8.4 ns or less, loss
may occur; on average, it is equal to the set duty.
Setting range
Normal range 0.0100% to 99.9900% (0.0001% resolution)
