4. BASIC OPERATION
c) Gate oscillation setting screen
1st page: Screen for the basic parameters
These are the common setting items that are common to all the oscillation modes.
Press the NEXT
key to display the
2nd page.
Indicates that the 1st
page is displayed.
Set the oscillation
mode to [Burst].
Oscillation start/stop
phase setting.
Oscillation start/stop phase [Phase]
This is the phase at which oscillation starts and stops.
2nd page: Screen for the gate oscillation settings
Press the NEXT
key to display the
1st page.
Indicates that the 2nd
page is displayed.
Set burst mode to [Gate].
Stop level
Trigger
Sync output Oscillation stop unit
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.

p.119
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..

p.121
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]..

p.120
Set [OscStop] (oscillation stop unit) on the 2nd page of the setting screen to [Cycle] (1 cycle)
normally..

p.120
A trigger (gate) is required for gate oscillation. Refer to the following item.
