Oscillation start/stop phase [Phase]
This is the phase at which oscillation starts and stops.

Sync output
Stop level [StpLvl]
This is the signal level during oscillation stop. The level can be set to either off or on. Normally, it
is set to off..

p.120
Trigger [Trig]
This is the trigger condition (gate condition). Internal and external can be chosen as the trigger
source..

p.119
Oscillation stop unit [OscStop]
This is the oscillation stop unit. One cycle and 0.5 cycles can be chosen from. Normally, 1 cycle is
set..

p.120
Sync output [SyncOut]
This is the output signal from the sync/sub-output terminal. Waveform reference phase
synchronization and burst synchronization can be chosen from.

d) Waveformsforwhichautoburstisnotpossible
Gate oscillation is not possible for DC.
Gate oscillation can be done for noise, but the operation differs from that of other waveforms..

e) Settingitemsrequiredforgateoscillation
On the 1st page of the setting screen, set [Phase] (oscillation start/stop phase).
Normally, set [StepLvl] (stop level) on the 2nd page of the setting screen to [Off]..

Set [OscStop] (oscillation stop unit) on the 2nd page of the setting screen to [Cycle] (1 cycle)
normally..
