Getting Started

This chapter provides information to help get you started so that your HP 70902A IF section

is serviced prop erly.

This chapter answers the questions \What is servicing?" and \When is servicing needed?". It

then describes the procedures used to return your HP 70902A IF section to Hewlett-Packard

for servicing if you choose not to p erform the servicing yourself.

Getting Started 1-1

What is servicing?

Servicing includes:

adjusting

troubleshooting

repairing

testing

All areas of servicing are explained in this service guide. This service guide is used to:

describe all adjustment procedures

illustrate module-level blo ck diagrams and interconnect diagrams

illustrate the pro cedures for removal and replacement of ma jor assemblies

explain module verication testing

In this service guide, when we refer to testing, we are referring to module verication tests.

Module verication tests should not be confused with verication of operation tests or

performance tests.

Module

Verication Tests

Module verication tests are used, during service, to test modules so

that when assembled into a system, the system meets the system's

specications.

Verication of

Operation Tests

Verication of op eration tests are used to v

instrument and to verify that the instrument meets approximately 80% of

its measurement related sp ecications.

For information related to verication of operation tests, refer to the

HP 70000 Modular Spectrum Analyzer Instal lation and Verication

Performance Tests

Manual

Performance tests are used to verify the proper operation of a complete

.

modular measurement system (MMS) to full system sp ecications.

For information related to performance tests, refer to the documen

for the HP 11990A p erformance test software.

When is servicing needed?

Servicing is needed:

if error messages are displayed on your HP 70000 Series display

to perform repairs or adjustments or b oth

to verify the correct operation of your HP 70902A IF section

or, if applicable, when upgrading rmware

erify the proper operation of an

tation

If you determine that your HP 70902A IF section needs servicing, you can p erform the

servicing yourself or, you can return your HP 70902A IF section to a Hewlett-Packard service

center.

1-2 Getting Started

If you want Hewlett-Packard to service your HP 70902A IF section

Before calling Hewlett-Packard or returning your HP 70902A IF section for service, please

read your warranty information. Warranty information is printed at the front of this service

guide.

In any correspondence or telephone conversations, refer to the HP 70902A IF section by

its full mo del number and full serial number. With this information, the Hewlett-Packard

representative can determine whether your unit is still within its warranty period.

Determining your HP 70902A IF section's serial number

When a mo dule is manufactured by Hewlett-Packard, it is given a unique serial number. This

serial number is attached to a label on the front frame or front panel of the module. A serial

number lab el is in two parts. (Refer to Figure 1-1.) The rst part makes up the serial number

prex and consists of four digits and a letter. The second part makes up the serial number

sux and consists of the last ve digits on the serial number label. The serial number prex is

the same for all identical mo dules; it only changes when a change in the electrical or physical

functionality is made. The serial number sux, however, changes sequentially and is dierent

for each module.

Getting Started 1-3

Returning your HP 70902A IF section for service

Hewlett-Packard has sales and service oces around the world to provide complete supp ort

for your HP 70902A IF section.To obtain servicing information or to order replacement parts,

contact the nearest Hewlett-Packard sales and service oce listed in Table 1-2.

Use the following pro cedure to return your HP 70902A IF section to Hewlett-Packard for

service:

1. Fill out a service tag (available at the end of this service guide) and attach it to the

instrument. Please b e as specic as possible about the nature of the problem. Send a copy

of any or all of the following information:

any error messages that appeared on the HP 70000 Series display

a completed Performance Test Record

any other specic data on the p erformance of the HP 70902A IF section

Caution

Damage can result if the original packaging materials are not used. Packaging

materials should be anti-static and should cushion the HP 70902A IF section

on all sides.

Never use styrene pellets in any shape as packaging materials. They do not

adequately cushion the instrument or prevent it from moving in the shipping

container. Styrene pellets can also cause equipment damage by generating

static electricityor by lodging in fan motors.

2. Place the HP 70902A IF section in its original pac

kaging materials (see Table 1-1 ).

If the original packaging materials are not available, you can contact a Hewlett-Packard

sales and service oce to obtain information on pac

kaging materials or you may use an

alternative packing material referred to as \bubble-pack". One of the companies that

makes bubble-pack is Sealed Air Corporation of Commerce, California, 90001.

3. Surround the HP 70902A IF section with at least 3 to 4 inc

hes of its original packing

material or bubble-pack to prevent the HP 70902A IF section from moving in its shipping

container.

4. Place the HP 70902A IF section, after wrapping it with packing material, in its original

shipping container or a strong shipping container that is made of double-walled corrugated

cardboard with 159 kg (350 lb) bursting strength.

The shipping container must be both large enough and strong enough to accommodate an

HP 70902A IF section and allow at least 3 to 4 inches on all sides for packing material.

5. Seal the shipping container securely with strong nylon adhesive tape.

6. Mark the shipping container \FRAGILE, HANDLE WITH CARE" to help ensure careful

handling.

7. Retain copies of all shipping pap ers.
