d) Waveform that gate oscillation is unavailable
DC cannot perform gate oscillation. Noise can perform gate oscillation, however, the action differs
from other waveforms.

P.4-101
e) Setting items necessary for gate oscillation
Set the oscillation start/stop phase [Phase] on the first page of the setting screen.
The stop level [StpLvl] on the second page of the setting screen is usually set as Off [Off].

P.4-101
The oscillation stop unit [OscStop] on the second page of the setting screen is usually set as 1 cycle
[Cycle].

P.4-100
A trigger (gate) is necessary for gate oscillation. See the next section.
f) Trigger (gate) setting for gate oscillation
Internal trigger oscillator, external signal, manual trigger operation, and remote trigger can be used
as a trigger (gate).
While a gate signal is On, the TRIG'D lamp above the TRIG key lights up.
Set the trigger source in the trigger [Trig] on the second page of the setting screen The trigger delay
is fixed to the minimum value.

Trigger source setting
A trigger source can be selected from internal [Int] or external [Ext].
When a trigger source is internal [Int], a trigger cycle can be set. At this time, the gate signal is
square waves with duty 50%.
When a trigger source is external [Ext], the polarity of a trigger can be set.
In addition, channel 2 can select the channel 1 trigger source [Ch1]. (WF1968 only) In this case, the
trigger source selected in channel 1 is shared.

How to use manual and remote triggers
Manual trigger operation and remote trigger operation is effective, regardless of the trigger source
setting.
The TRIG key can be used for manual trigger operation.
While the TRIG key is pressed, the gate signal is On. However, in case of the WF1968,
the TRIG key works for the channel whose 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.
