3.3 Basic operation
WF1946B
3-27
If the phase of the squarewaves (fixed duty) or squarewaves (variable duty) is changed,
multiple pulses may be output in one cycle, as shown below.
If the duty of the squarewaves (variable duty) is changed, multiple pulses may be output in one
cycle, as shown below.
If the pulse width is larger than 75 ns after the duty is changed, it is possible to suppress the output of
multiple pulses in one cycle. Therefore, set DUTY-VALID to CYCLE.
Note, however, that this setting cannot be made if the oscillation mode is SWEEP or MODU.

If DUTY-VALID is set to CYCLE, the set duty will be reflected in the subsequent cycles.
Even though DUTY-VALID is set to CYCLE, extra pulses may be output if the frequency or phase is
changed.
Operation when DUTY-VALID: IMMED
Operation when DUTY-VALID: CYCLE
The setting will be reflected at the same time that the duty changes
Duty change
The setting will be reflected in the subsequent cycles
