BASIC OPERATION
IM FG410-01EN
Gated single-shot one-way sweep
Gated single-shot shuttle sweep
k) To set trigger condition for single-shot sweep and gated single-shot sweep
The trigger can be selected from internal trigger oscillator, external signal, manual trigger
manipulation, and remote trigger manipulation.
Upon receipt of a trigger, the TRIG’D lamp next to the MAN TRIG key lights.
The trigger condition is set with [Trig] (trigger) on the 2nd page of the setting screen.
■ Trigger source setting
The trigger source can be chosen from [Int] (internal) and [Ext] (external).
When the trigger source is [Int] (internal), the trigger period can be set.
When the trigger source is [Ext] (external), the trigger polarity can be set.
If the trigger source is set to [Ext] (external), a TTL level trigger signal is input to the
external trigger input terminal (TRIG IN).
Sweeping can be started and stopped independently of the trigger source setting through
input of a logic signal to the multi-I/O connector.

Usage of manual trigger and remote trigger

and the stop phase setting is the oscillation stop phase.
