Getting Started
A Sample Session
1.5 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 HP 8163A Lightwave
Multimeter or HP 8164A Lightwave Measurement System, the
HP 81689A Tunable Laser module, and the HP 81532A 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/HP/HRL to Diamond HMS-10/
HP patchcord, HP 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
µ
W.
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 1-17. 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.
