How to Use Output Triggering
You can configure your Tunable Laser module to output a trigger when the
instrument performs certain tasks.
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 Tunable Laser 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 80 .
Figure 80 Output Trigger Mode
4 Move to one of the following, by using the cursor key:
• <Disabled>, the output trigger mode is disabled.
•<Modulation>, the output trigger connector outputs a TTL signal at the fre-
quency of the internal modulation. This signal is output whether the laser is
switched on or off.
•<Step Finished>, a trigger is output after every step of a sweep finishes.
•<Sweep Finished>, a trigger is output after a sweep cycle finishes.
•<Sweep Started>, a trigger is output after a sweep cycle starts.
5 Press Enter.
If you choose <Step Finished> and a <Continuous> sweep, the
wavelength interval between hardware triggers is set by the [Step]
parameter, although, the sweep is not stepped.
