Tunable Lasers How to Set the Power

NOTE If you select <Both (master:2)> or <Both (master:1)> as the regulated
path, both channels output optical power. You can only view or set the
parameters for the primary optical output, for example, the high
power output for <Both (master:2)>.
The LED beside the primary optical output is lit constantly, while the
LED beside the secondary optical output flashes. For example, if you
select <Both (master:2)> as the regulated path, the LED beside Output
2, the High Power Output, is lit constantly and the LED beside Output
1, the Low SSE optical output, flashes.
How to Set the Optical Output
1 Move to [Output] and press Enter.
2 Move to your chosen optical output and press Enter.
How to Enable the Optical Output
3 Move to [State] and press Enter.
4 Move to <On>, by using the cursor key, and press Enter to enable the
output. The LED beside the optical output is lit constantly.
NOTE If you enable the laser output for a module with two optical outputs by
pressing the Active hardkey on the module’s front panel, you
automatically choose the optical output for that module. For example,
if you press the Active hardkey beside Output 1, the Low SSE optical
output, you choose <Low SSE> as the optical output, the LED beside
the Output 1 lights constantly, and you see the screen in Figure 64.
Furthermore, if you then proceed to press the A
CTIVE hardkey beside
Output 2, the High Power Output, you choose <Both (master:1)> as
the optical output, the LED beside the Output 2 flashes.
If you press the Active hardkey beside a flashing LED, you disable the
unregulated optical output. If you press the Active hardkey beside a
constantly lit LED, you disable both optical outputs.
How to Set Power and Attenuation
Attenuator If your tunable laser has an built-in optical attenuator, you can set the
laser output power and then set the attenuation.
1 Move to the Tunable Laser channel and press [Details].
2 Choose the Output 2, the high power output, for a Tunable Laser
module with two optical outputs, as described in “How to Set the
