4. BASIC OPERATION
4.9.5 Triggeredgateoscillation
Triggered gate oscillation is gate oscillation that switches the gate on/off each time a trigger is
received.
The settings and manipulations are done on the Oscillator setting screen. “Oscillator” is
displayed at the top left of the Oscillator setting screen. When another screen is displayed,
press the
MENU
MENU key to display the top menu, then select [Oscillator] and press the
ENTER
ENTER key.
a) Triggeredgateoscillationexample
The following example is for oscillation start/stop phase = 30°, oscillation stop unit = 1 cycle, stop
level: off.
After the gate signal becomes off, oscillation stops once the oscillation start/stop phase is reached.
Gate on
Gate off
Internal gate signal

b) Settingtheoscillationmodetotriggeredgateoscillation
Set [Mode] (oscillation mode) to [Burst]
on the oscillator setting screen. The
oscilla-tion mode is switched to the
burst oscilla-tion mode as a result. In
the burst oscilla-tion mode, the setting
screen consists of two pages, which
can be toggled with the
NEXT
NEXT key.
Next, set [BrstMode] (burst mode) on
the 2nd page of the burst oscillation
mode setting screen to [TrigGate]
(triggered gate oscillation).
Select [Burst] in
[Mode] and then
press the ENTER
key.
Select [TrigGate] in
[BrstMode] and then
press the ENTER
key.
