Laser module and press E
b
Enter 1540.000 and press E
9 How to set the modulated power for the Tunable Laser module:
a
If power is not displayed in Watts, move to the [P
parameter and press the [Power Unit] softkey.
b
Move to <W>, using the cursor key, and press E
c
Move to the [P
d
Enter 500.000.
Change units to µW, if necessary, using the [Unit+] or
e
[Unit−] softkey.

10 How to set the modulation frequency for the Tunable Laser
module:
a
Select the [F
REQUENCY
b
Change units to kHz, if necessary, using the [Unit+] or
[Unit−] softkey.
c
Enter 100.000 and press E
11 For the Tunable Laser module, press the button beside the
Optical Output. The green LED should switch on to indicate that
the laser is now active.
You should notice that the power reading is approximately half the
value set on the Tunable Laser module. This is because the output is
modulated by a square wave with a 50% duty cycle.
