4.9 Setting and Operation of Burst
WF1967/WF1968 4-104
The TRIG key can be used for manual trigger operation.
However, in the case of WF1968, the TRIG key only works on the channel side where the display is
active. For the channel where the display is active,

P.4-20
When only manual trigger operation and remote trigger operation are used for a trigger, set the
trigger source as external [Ext]. Moreover, we will recommend that the polarity is set as [Off] to
avoid malfunctions caused by exogenous noise.
g) To start triggered gate oscillation
→ Trigger
When the trigger is accepted and the internal gate signal is On, oscillation starts.
Internal trigger oscillator, external signal, manual trigger operation, and remote trigger can be used
as a trigger.
h)
To output a burst synchronization signal → Synchronous output setting
set synchronization output [SubOut] on the third page of the setting screen. Select from following
table.
Modulation function on and internal modulation Modulation function off or external modulation
Waveform reference phase synchronization[Sync] Waveform reference phase synchronization[Sync]
Burst synchronization [BrstSync] Burst synchronization[BrstSync]
Internal modulation synchronization [ModSync] -
Internal modulation waveform [ModFctn] Sub waveform [SubFctn]
Output disabled [Off] Output disabled [Off]

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 synchronized with the gate 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. Note that it is different from a gate signal.
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 synchronization output
signal.
i) To oscillate
in half cycle → Oscillation stop unit as half cycle
When you want to stop oscillation every half cycle, set the oscillation stop unit [OscStop] as half
cycle [HalfCycle] on the second page of the setting screen. Usually, set to 1 cycle [Cycle]. When it
is set to 1 cycle [Cycle], the oscillation has an integer cycle.
