Figure 1-20 The Trigger/Output Button

1.Press Trigger Button, choose internal/external or manual Trigger (Manual Trigger can only be used in Sweep and N-Cycle Burst)

z The default setting for Trigger is “Internal”. In this mode, when the Sweep or Burst Mode is also selected, the Generator will continuously generate burst. At this time, press Trigger button, the instrument will shift from the “Automatic” Trigger mode into “Manual” Trigger mode.

z When the generator uses the” External” Trigger Mode, if the Sweep or the Burst Mode is selected, the signal will be continuously generated. At this time, press Trigger button, the instrument state will not change, and it will show the information “The instrument has already been triggered”.

z Every time you press the Trigger button, “Manual” Trigger will start a sweep or generate a burst. Press the button again, and the generator will be triggered again.

2.Press Output Button, activate or deactivate the output signal.
