How to Set the Output Power of a CW Signal

How to Set Output Power

To set the output power to 555.000 µW:
Attenuator
If your tunable laser has an built-in optical attenuator, move to
[Power Mode], press Enter, move to <Automatic>, and press Enter.
1 Move to the power parameter, [P], and press [Pwr unit].
2 Move to <W> and press Enter.
3 Press Enter to start editing the output power value.
4 Enter 555.000, press [Unit+] or [Unit−], as required, to select µW as
the power units, and press Enter.

How to Set the Optical Output

To set the Optical Output of a Tunable Laser module with two optical
outputs:
1 Press [Details].
2 Move to [Optical Output] and press Enter.
3 Use the Modify Knob to move to one of the following:
– <High Power (2)>, a high power optical output, for example, for
use in tesing Erbium Doped Fiber Amplifiers (EDFAs), you see a
screen similar to Figure 63,
– <Low SSE (1)>, a lower power optical output with low Source
Spontaneous Emission (SSE), for example, for use in passive
component test, you see a screen similar to Figure 64,
– <Both (master:2)>, where both optical outputs can be enabled but
only the output of the high power optical output can be regulated,
and
– <Both (master:1)>, where both optical outputs can be enabled but
only the output of the low SSE optical output can be regulated.
