General Safety Considerations
WARNING
These servicing instructions are for use by qualied personnel only.To
avoid electrical shock, do not perform any servicing unless you are
qualied to do so.
The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the instrument from all voltage sources while it is
being opened.
The power cord is connected to internal capacitors that may remain live
for ve seconds after disconnecting the plug from its power supply.
This is a Safety Class 1 Product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact.
Any interruption of the protective conductor inside or outside of the
instrument is likely to make the instrument dangerous. Intentional
interruption is prohibited.
For continued protection against re hazard, replace fuse only with
same type and ratings, (type nA/nV). The use of other fuses or materials
is prohibited.
WARNING
Before this instrument is switched on, make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside
or outside the instrument, or disconnection of the protective earth
terminal can result in personal injury.
Before this instrument is switched on, make sure its primary power
circuitry has been adapted to the voltage of the ac power source

Getting Started
This chapter provides information to help get you started so that your color display is serviced
properly.
This chapter answers the questions \What Is Servicing?" and \When Is Servicing Needed?".
It then describes the procedures used to return your color display to Hewlett-Packard for
servicing.
Getting Started 1-1

What Is Servicing?
Servicing includes testing, adjusting, calibrating, troubleshooting, and repairing.
There are dierent categories of testing available. These categories are module verication
tests, system verication of operation tests, and system performance tests.
Module
Verication Tests
Module verication tests are used to test modules so that when assembled
into a system, the system meets the system's specications. These sets of
tests are used during servicing.
System
Verication of
Operation Tests
System verication of operation tests are used to verify the proper
operation of an instrument and to verify that the instrument meets
approximately 80% of its measurement related specications. These sets of
tests are subsets of system performance tests.
System
Performance
Tests
System performance tests are used to verify the proper operation of a
complete modular measurement system (MMS) to full system specications.
This service guide provides information related to testing, adjusting, calibrating,
troubleshooting, and repairing your color display; it also provides information on module
verication tests. These sets of tests are used during servicing.
For information related to system verication of operation tests
, refer to the HP 70000 Modular
Spectrum Analyzer Installation and Verication Manual , and for information related to
system performance tests, refer to the documentation for HP 11990A system performance test
software.
When Is Servicing Needed?
Servicing is needed:
if error messages are displayed on your HP 70000 Series display
if an ERROR LED or FAULT LED is on
to perform repairs or adjustments or both
to verify the correct operation of your color display
or, if applicable, when upgrading rmware
If you determine that your color display needs servicing, you can perform the servicing
yourself or, you can return your color display to a Hewlett-Packard service center.
1-2 Getting Started

If You Want Hewlett-Packard to Service Your Color Display
Before calling Hewlett-Packard or returning your color display 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 color display by its full model
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 Color Display's Serial Number
When a module 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 label 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 modules; it only changes when a change in the electrical or physical
functionallity is made. The serial number sux, however, changes sequentially and is dierent
for each module.
