a Select the [Frequency] parameter and press Enter.
b Enter 100.000 and press Enter.
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.
