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

500W

atts

.

Requirements

The

sample

session

is

written

for

an

(It

is

assumed

that

the

power

sensor

is

inserted

in

channel

A).

T

o

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

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
