Installation and Operation Verification

of the Optical Spectrum Analyzer

The HP 71450B/1B/2B Optical Spectrum Analyzer Systems

The HP 71450B/1B/2B are precongured systems that include either an HP 70950B, HP

70951B, or HP 70952B optical spectrum analyzer mo dule, an HP 70004A, and an optical

spectrum analyzer keypad. The HP 70950B/1B/2B optical spectrum analyzer modules may

be installed either in an existing HP 70004A display or in an HP 70001A mainframe.

iii

The HP 70950B/1B/2B Optical Spectrum Analyzer Modules

The HP 70950B, HP 70951B, and HP 70952B are 4/8-width mo dules that must be inserted

into either an HP 70004A or an HP 70001A mainframe. An optical sp ectrum analyzer keypad

is shipped with b oth the mo dules. If you are using a mono chrome display (or no displayat

all), certain features (such as color) will not be available.

iv

The Optical Spectrum Analyzer Keypad

The optical spectrum analyzer keypad provides front-panel keys that serve the same purpose

as some of the softkeys. This allows you easy access to frequently-used functions without

losing your p osition in a softkey menu and saves you steps when making measurements.

This keypad may only be used with the HP 70004A. However, even if this keypad is not

installed, all of the optical spectrum analyzer's functions are accessible using the softkeys.

The keypad is already installed when you receive an HP 70950B, HP 70951B, or HP 70952B.

Installation instructions for the optical spectrum analyzer keypad are provided in Chapter 1.

The optical spectrum analyzer keypad is not the only keypad that will work with the optical

spectrum analyzer. If you haveakeypad from another product installed and press one of its

eys, the

The Operation Verification Tests

The operation verication tests are designed to giveyou a high level of condence that the

optical spectrum analyzer is op erating correctly and meets its specications. The op eration

verication tests consist of:

Automated Tests - The op eration verication test disks are shipp ed with the optical

spectrum analyzer. You will need a computer system with the HP BASIC op erating system

and test equipment to p erform the operation verication tests on the optical sp ectrum

analyzer.

Manual Operation and Verication Tests - These tests can be performed if you do not have

the specic equipment required to perform the automated version.

Manual Operational Checks - These tests verify the functionality of instrument mo des on

the HP 70951B optical spectrum analyzer mo dule.

Locate the eight HP-MSIB address switches on

top of the mo dule. These switches are factory

preset to row address 0 and column address 23.

Each device that communicates over the

HP-MSIB bus must have a unique 8-bit binary

HP-MSIB address. This address is determined

by the eight address switches. The three most

signicant bits (MSB) determine the row

address. The ve least signicant bits (LSB)

determine the column address. This manual

refers to the decimal equivalent of the binary

If You Have a Problem During Installation

Introduction

This chapter will help you correct problems you may encounter during installation of the

optical spectrum analyzer. The problem or symptom is listed at the top of each page. Most

problems have a brief description or explanation, followed byachecklist of items that could

be causing the problem. Using the checklist of possible solutions will help you correct the

problem. If the problem is internal to the optical spectrum analyzer, the checklist will also

help to identify the faulty module, display, or mainframe.

What to Expect When You Turn on the Optical Spectrum Analyzer

Each time the optical sp ectrum analyzer is turned on, the following actions take place:

1. The module self-test pro cedure turns on all the LEDs, except the STATUS LEDs. The

STATUS LEDs will turn on one second later. Refer to Figure 2-1.

This description identies the optical spectrum analyzer mo dule LEDs that light.

Depending on the display or mainframe used, their LEDs will also light during turn on.

2. After the preliminary self-test, all optical spectrum analyzer mo dule front-panel LEDs are

turned o.

3. The display's model number is briey displayed on screen.

4. The system begins running an instrument INITIALIZING routine.

5. At the b eginning of the INITIALIZING routine, the ACT LED lights and remains lit.

6. At the end of the INITIALIZING routine, the MEASURE LED lights as the optical

spectrum analyzer sweeps across the display. If the mo dule is an HP 70951B, the

MONOCHROMATOR INPUT LED will also light.

The HP-IB LEDs on the front panel of the optical sp ectrum analyzer are turned on then o,

one at a time, during the optical sp ectrum analyzer's self-test. The four HP-IB LEDs are:

service request (SRQ), talk (TLK), listen (LSN), and remote (RMT). Refer to Figure 2-7 for

the location of each of the HP-IB LEDs. The HP-IB LEDs reveal the status of the optical

spectrum analyzer module when it is b eing controlled by a computer.

requested computer service. Check for error messages on the display.

TLK

LSN

RMT

The talk (TLK) and listen (LSN) LEDs light when a controller has addressed the

optical spectrum analyzer to talk or listen over the HP-IB. The remote (RMT) LED

lights if the remote enable (REN) line is asserted and the optical sp ectrum analyzer

is addressed byacontroller.

If the TLK, LSN, or RMT LEDs remain on after the self-test:

Check that no HP-IB address conicts with other equipment on the HP-IB bus.

Two instruments on the HP-IB bus that have the same HP-IB address will cause an error.

Remove the HP-IB bus from the optical sp ectrum analyzer.

The display HP-MSIB fault indicator light and the mainframe I/O CHECK status indicator

light indicate the status of the HP-MSIB. If either of the lights are on, there is a problem with

the HP-MSIB. Refer to Figure 2-8 for the lo cation of the HP-MSIB indicator light on the

display and the lo cation of the I/O CHECK indicator light on the mainframe.

Verify that the power to all mainframes and stand-alone display instruments is on.

Check that all HP-MSIB cables are securely connected and ensure that they are connected

serially to form a lo op.

Checkfortwo mo dules in the system with the same HP-MSIB address. Refer to \Step 3.

Check the System's HP-MSIB Addresses." in Chapter 1 for instructions.

Check for a faulty mainframe or stand-alone displayby removing all of the HP-MSIB cables

and noting the state of the indicator light as each cable is removed.

If the Optical Spectrum Analyzer Needs to be Returned for Service

When an instrument is returned to a Hewlett-Packard service oce for servicing, it must be

adequately packaged and have a complete description of the failure symptoms attached.

When describing the failure, please be as specic as possible about the nature of the problem.

Include copies of additional failure information (such as instrument failure settings, data

related to instrument failure, and error messages) along with the instrument being returned.

Please notify the service oce before returning your instrument for service. Any sp ecial

arrangements for the instrument can be discussed at this time. This will help the HP service

oce repair and return your instrument as quickly as possible.

Repackaging an instrument requires original shipping containers and materials or their

equivalents. Hewlett-Packard oces can provide packaging materials identical to the original

materials.

Caution

Packaging materials not specied can result in instrument damage. Never

use styrene pellets to package electronic instruments. The pellets do not

adequately cushion the instrument, do not prevent all instrumentmovement,

Serial Number and Option Labels

Serial Number Labels

A serial-number lab el is attached to the front frame of the optical spectrum analyzer

module. The serial number is divided into two parts. The rst four digits and letter are the

serial-number prex; the last ve digits are the sux. Refer to Figure 3-1.

The prex is the same for all identical mo dules; the prex changes only when a signicant

modication is made to the pro duct. The sux, however, is assigned sequentially and is

dierent for each module.

Option Labels

If the optical sp ectrum analyzer mo dule is ordered with an option, a lab el indicating the

option will be attached to the front frame of the mo dule. For example, if you have an optical

spectrum analyzer module with a built-in current source, a label on the module's front frame

will show \Option 001." Refer to Figure 3-1 for the lo cation of the lab el.

have:

A minimum of 2.5 to 4 megabytes of RAM (depending on the display conguration used).

An HP-IB interface.

A 3.5 inch double-sided exible disk drive.

A hard disk drive with 4 megabytes available space.

1. Connect the optical spectrum analyzer to the computer port.

There are two possible congurations:

If the computer has an HP 98624A HP-IB interface:

Connect your optical sp ectrum analyzer to the port labeled HP-IB SELECT CODE 8.

Check that the address switch on the HP 98624A HP-IB interface matches the HP-IB

controller device address.

Step 2. Install the Software on an SRM or HFS Hard Disk

Note

For best results, install the op eration verication software on, and run the

tests from, a hard disk drive. If you want to run the tests from a exible disk

drive, see \Optional: Running the Operation Verication Tests from a Flexible

Disk Drive".

SRM is an acronym for shared resource manager; HFS is an acronym for hierarchical le

structure. This step is a general pro cedure for installing the op eration verication software

on an SRM or HFS hard disk system. For detailed information on creating directories and

copying les, refer to the appropriate SRM or HFS hard disk manuals.

Caution

Make backup copies of all write-protected disks. If the program data on an

individual disk should become altered, it cannot b e ordered separately.The

entire set of disks must be ordered to replace any one. Before making backup

copies of write-protected disks, initialize the backup disks:

For example:

":,700,0",2,3.

If you do not have an optical attenuator or a p olarization controller available as part of your

test equipment, you can still perform the wavelength accuracy and the resolution bandwidth

accuracy tests. The optical attenuator and the polarization controller are optional equipment

for these two tests. This procedure will showyou how to edit the TSCRIPT MS le so that

you may perform the wavelength accuracy and the resolution bandwidth accuracy tests

without the optical attenuator and the polarization controller.

Precision Resistor and RC Network

If you have an optical sp ectrum analyzer with an Option 001 (the current source option) and

you want to perform the current source operation verication test, you will need a precision

resistor and RC network. The schematic diagram and parts list for building the network are

provided. Test points are designated on the schematic diagram; these test points are referred

to in the current source's op eration verication test description in Chapter 6.

Operation Verification Test Descriptions

Introduction

Operation verication tests are designed to giveyou a high condence level that your optical

spectrum analyzer is working properly. These tests are also designed to be completed in the

least time possible.

All op eration verication tests are automated and are designed to be controlled bya

computer. However, three of the op eration verication tests also havemanual versions of the

test. These manual op eration verication tests are designed to b e used if you do not havethe

specic test equipment required for the automated version of the test.

The operation verication test descriptions and pro cedures describe the operation verication

tests for the HP 70950B/1B/2B. However, the input of the monochromator for the HP

70950B/2B and for the HP 70951B are labeled dierently. In this chapter, the term

input

refers to both the HP 70950B/2B's OPTICAL INPUT and to the HP 70951B's

MONOCHROMATOR INPUT.

Unless otherwise specied, optical connections should b e made with 9/125m patchcords

using FC/PC or Diamond HMS 10 physical contact connector interfaces. To prevent damage

to your optical sp ectrum analyzer and ensure accurate measurements, clean all connectors and

optical input bers before beginning the operation verication tests.

Note

To minimize interconnection changes, the HP 8157A optical attenuator and

the HP 11896A polarization controller are listed as standard equipment for all

tests. However, they are included in a test setup illustration only when they

are required by that test. If you haveveried model numbers and addresses

for the optical attenuator and polarization controller in \Step 7. Verify the

Test Equipment" in Chapter 4, the program will include them in the setup

directions.

Automated Test Procedures

Each automated operation verication test in this section summarizes the purpose of the

test, lists the equipment required to p erform the test, explains how the equipment is set up,

describes the test, and suggests the assemblies or items to check if the instrument fails the

operation verication test.

The measured results of the automated op eration verication tests are compared with the

specications for the optical sp ectrum analyzer. The operation verication software records

whether the measured results of the test meets the specications. Refer to \Specications and

Characteristics" in the Reference manual for the specications.

A list of test equipment required to perform these operation verication tests is located

in \Recommended Test Equipment" in Chapter 5 and in the equipmentlistofeachtest

description. The computer and its peripheral equipment are not listed in \Recommended

Test Equipment" in Chapter 5 or in the equipment list of each test. For details regarding

the computer, refer to \Step 1. Set up the Hardware for Operation Verication Testing" in

Chapter 4.

Description

The 1300 nm DFB laser and the 1550 nm DFB laser should have their wavelengths measured

and calibrated byawavemeter to the nearest tenth of a nanometer.

The wavelength measured on the optical spectrum analyzer in both rst and second order

operation is compared to the known wavelength of the HeNe laser (632.8 nm).

Then, with the 1300 nm DFB laser's OPTICAL OUTPUT connected to the optical input of

the optical spectrum analyzer under test, the optical sp ectrum analyzer under test is set to

automatic grating order. The center wavelength is set to the calibrated wavelength of the

1300 nm DFB laser. The dierence between the measured wavelength and the calibrated

wavelength of the 1300 nm DFB laser is compared to the sp ecication.

If the 1550 nm DFB laser is selected, the test is repeated for this source.
