A Sample Session

This sample session shows you how to measure the power of a modulated signal
at a single wavelength.
The sample session is written for the Agilent 8163A Lightwave Multimeter or
Agilent 8164A Lightwave Measurement System, the Agilent 81689A Tunable
Laser module, and the Agilent 81632A Power Sensor. To perform the sample
session as described here, you also need a patchcord (if you are using the
81000AI Connector interface, then a Diamond HMS-10/Agilent/HRL to
Diamond HMS-10/Agilent patchcord, Agilent 81109AC).
How to Measure the Power of a
Modulated Signal
We want to measure the power of a 1540 nm signal, modulated by a 100 kHz
square wave, at 500 µW.
1 Make sure that all your connectors, and connector interfaces are clean.
2 Make sure that the Optical Output of the Laser Source is not active.
3 Connect the output of the Laser Source to the input of the Power Sensor
module, as shown in Figure 27. You must connect the correct fiber end
connector for your Tunable Laser module:
a For straight contact connectors, use a straight contact fiber end connector
with a black sleeve.
b For angled contact connectors with a green sign beside the Tunable Laser
module's optical output connector, use an angled contact fiber end
connector with a green sleeve.
