Optical spectrum analyser

This chapter describes the different steps in carrying out a spectrum analysis of

an optical signal by an MTS equipped with a WDM 507x module:

❏

OSA configuration test

❏

Display of spectrum and results of the WDM analysis

Configuration of the instrument

After connecting the fiber to be tested to the optical connector, you must select

the OSA module (see "Instrument Set up" on page 3-11), then setup this module.

OSA test setup

To setup the MTS

e

 for an OSA test on a fiber, press the 

SET-UP

 button then the

<Test setup> key. The different measurement parameters are displayed. 
You may :

1.

either choose the default values by pressing the key <Auto Mode>.

Auto Mode Configuration

:

•

Sweep : Continue

•

High Sensitivity: No

•

Resolution : Full

•

Channel Detection: First sweep

•

Signal Threshold: Auto

•

Statistic Mode: No

•

SNR Methode : Left & Right.

•

S <-> N Distance: Auto

•

Noise Acq. BW: 0.100 nm.

•

Start Screen: Auto

2.

or define your own configuration.

The parameter to be modified must be chosen by using the direction arrow 

keys «

↓

» and «

↑

». The screen will then display the possible options: use the 

direction arrow keys 

←

 and 

→

 to make a choice.

The different parameters proposed are described below.
