How to Set the Trigger Configuration
The trigger level at the external trigger connectors is by default active high,
this means when a trigger rises above the high TTL level (rising edge), a
trigger is accepted.
You can select three modes of triggering from the trigger configuration
menu:
• <None>, which you should choose if you do not want to use triggering.
• <Default>, which you should choose if you want to enable the trigger
connectors.
• <Pass Through>, which you should choose if you want an input trigger to
automatically generate an output trigger. This allows you to trigger another
instrument almost simultaneously.
• <Feedback>, which you should choose if you want an output trigger to
automatically generate an input trigger. For example, using this mode, you
could trigger each step of a wavelength sweep with just one externally
generated input trigger.
To change the triggering mode:
1 Press the Config hardkey.
2 Move to the <Trigger> menu option and press Enter. You see a box displaying
the available triggering modes.
