4.9 Setting and Operation of Burst
WF1967/WF1968 4-92

When [Sync] is selected
Signals with TTL level that are rising at the reference phase of waveform are output from the
synchronization/sub-output terminal.

When [BrstSync] is selected
Signals with TTL level that synchronize with the burst oscillation are output from the
synchronization/sub-output terminal. It is low during oscillation and high while oscillation is
stopped, as show in the following figure.
When a signal under burst is observed with the oscilloscope etc., it can be used as a trigger signal of
the oscilloscope.

When [Off] is selected
The output will be low level. This helps to reduce interference from the common GND of externally
connected devices or the synchronization output signal.
i) How to use stop level
The level while oscillation is stopped is usually set by oscillation start/stop phase. It is also possible
to set by the ratio to the full scale of the amplitude independently.
Set the stop level [StpLvl] as On [On] on the second page of the setting screen, and set the level
with % value.
