4.5 Switching waveforms of synchronous signals (SYNC OUT)
WF1945B
4-61
„
When the oscillation mode is SWEEP
• STATE: Low level while sweeping from the start value to the stop value or stopped. Otherwise,
high level.
• PHASE: For squarewaves (variable duty), the same waveform as that for FUNCTION OUT.
Otherwise, high level while between 0 and 180 degrees of the waveform, and low level
while between 180 and 360 degrees.

When the oscillation mode is MODU
• STATE: STATE: Low level while executing modulation and between 180 and 360 degrees of the
modulated waves. Otherwise, high level.
• PHASE: For squarewaves (variable duty), the same waveform as that for FUNCTION OUT.
Otherwise, high level while between 0 and 180 degrees of the modulated waves, and low
level while between 180 and 360 degrees.
