Trigger Output Trigger output, ON or OFF
If this parameter is ON, B2900 sends an output trigger when it
changes the trigger state for the action specified by the Ch,
Layer, and Action parameters. See
Figure 6-8 on page 6-28.
Also see “DIO Configuration dialog box” on page 4-46 for
details on setting the trigger output timing.

present setting of the trigger output terminal. In the default
setting, it is the EXT1 terminal. It can be changed by the
following commands.
• Between initial state and arm layer
:ARM[:ACQ|:TRAN]:TOUT:SIGN
• Between arm layer and trigger layer
:TRIG[:ACQ|:TRAN]:TOUT:SIGN
• Between trigger layer and transient action
