How to Use Triggers
Some Laser Source modules allow you to output trigger signals to external
measurement instruments.
How to Use Output Triggering
You can configure the output trigger connector to output a TTL signal at
the frequency of the internal modulation of a Agilent 8163A/B Series Laser
Source module.
To set your module’s Output Trigger Configuration:
1 See “How to Set the Trigger Configuration” on page 69 for how to configure the
trigger connectors.
2 Move to the Laser Source channel and press [Menu].
3 Move to <Output Trigger Mode>, by using the cursor key, and press Enter. You
will see the screen in Figure 62 .

on or off.
