Hewlett-Packard to Agilent Technologies Transition

This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-

Packard’s former test and measurement, semiconductor products and chemical analysis

businesses are now part of Agilent Technologies. To reduce potential confusion, the only

change to product numbers and names has been in the company name prefix: where a

product name/number was HP XXXX the current name/number is now Agilent XXXX. For

example, model number HP8648 is now model number Agilent 8648.

HP 16555A.

Features

Some of the main features of the HP 16555A/D are as follows:

•64 data channels

•4 clock/data channels

•1016K memory depth per channel for the HP 16555A, 2032K memory depth per

channel for the HP 16555D

•110 MHz maximum state acquisition speed

•500 MHz maximum timing acquisition speed

•Expandable to 204 channels

Service Strategy

The service strategy for this instrument is the replacement of defective assemblies.

This service guide contains information for finding a defective assembly by testing

and servicing the HP 16555A/D state and timing analyzer modules.

This module can be returned to Hewlett-Packard for all service work, including

troubleshooting. Contact your nearest Hewlett-Packard Sales Office for more details.

In This Book

This book is the service guide for the HP 16555A/D 110-MHz State/500-MHz Timing Logic

Analyzer module. Place this service guide in the 3-ring binder supplied with your

HP 16500B Logic Analysis System Service Manual or HP 16500C Logic Analysis System

Service Manual.

This service guide is divided into eight chapters.

Chapter 1 contains information about the module and includes accessories for the module,

specifications and characteristics of the module, and a list of the equipment required for

servicing the module.

Chapter 2 tells how to prepare the module for use.

Chapter 3 gives instructions on how to test the performance of the module.

Chapter 4 contains calibration instructions for the module.

Chapter 5 contains self-tests and flowcharts for troubleshooting the module.

Chapter 6 tells how to replace the module and assemblies of the module and how to return

them to Hewlett-Packard.

Chapter 7 lists replaceable parts, shows an exploded view, and gives ordering information.

Chapter 8 explains how the analyzer works and what the self-tests are checking.

Operating System

With HP 16500B Mainframe

The HP 16555D Logic Analyzer requires operating system version v3.10 or higher.

For the HP 16555A, the version of the operating system software depends on the

programmable logic device that is the CPU interface. To verify the version of the

programmable device, first locate the device, which is at the front of the HP 16555A board. If

the programmable device has part number 16555-80001, then the device requires operating

system version v2.xx, and the maximum state acquisition speed is 100 MHz. If the device has

part number 16555-80002 or higher, then the device requires operating system v3.00 or

higher, and the maximum state acquisition speed is 110 MHz for single-clock, single-edge

clocking mode. You should always use the latest release, and must use version numbers that

are compatible with your device.

With HP 16500C Mainframe

The HP 16555A/D Logic Analyzer requires operating system version v1.00 or higher.
