1 Getting Started
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 8163A/B Lightwave Multimeter or
8164A/B Lightwave Measurement System, the Keysight 81960A Tunable
Laser module, and the Keysight 81634B 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/HRL to
Diamond HMS-10/patchcord, 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 mW.
1 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 26 on page -59. 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.
