How to Set the Modulation Output Mode
5
Move to <
Modout
> and press [OK].
6
Move to either of the following two menu items, by using the cursor key:
–
<
FRQ&RDY
>, where the modulation signal is combined with the laser-
ready signal, so that the output is kept low when there is no optical signal
being output, for example, when the laser is turned off or when you set the
attenuator to the dark position, or
–
<
FRQ
>, where the modulation signal is output all the time regardless of
laser state.
7
Press [OK].
8
Press [Close] to return to the overview or detail screen.
How to Use Triggers
Some Tunable Laser modules allow you to trigger the instrument to perform tasks
and to output trigger signals to external measurement instruments.
How to Use Input Triggering
You can configure your Tunable Laser module to perform certain tasks when you
apply a trigger to the Input Trigger Connector.
C A U T I O N
A maximum of 5 V can be applied as an external voltage to the Input Trigger
connector, see page 217.
Take care not to use the Trigger Output connector or the Remote Interlock
connector for modulation. Do not apply an external voltage to these connectors.
To set your module’s Input Trigger Configuration:
1
See
“How to Set the Trigger Configuration” on page 62
for how to configure
the trigger connectors.
2
Move to the Tunable Laser channel and press [Menu].
