Example 3 - Measuring the Power of a Modulated
Signal
Function
This program performs the same sequence as the rst part of the sample session
given in chapter 1. That is, to measure the power of 1540nm signal, modulated
by a 100kHz square wave, at 500
Watts.
Requirements
The sample session is written for an HP 8168E/F Tunable Laser Source, and
an HP 8153A Lightwave Multimeter with an HP 81532A Power Sensor (It
is assumed that the power sensor is inserted in channel A). To perform the
sample session as described here, you also need a connector interface for the
multimeter (for example, an HP 81000AI), and a patchcord (if you are using
the HP 81000AI, then a Diamond HMS-10/HP/HRL to Diamond HMS-10/HP
patchcord, HP 81109AC).
Setting Up the Equipment
1. Make sure that all your connectors, and connector interfaces are clean.
2. Make sure that the Optical Output on the laser source is not A
ctive.
3. Connect the output of the laser source to the input of the power sensor (as
shown in the gure below). Make sure that the connector with the orange
strain-relief sleeve is connected to the tunable laser source (the orange sleeve
indicates an angled connector).
